Caffeine pills for increased motivation -
Summary Curcumin is the active ingredient in turmeric. It has been shown to increase dopamine levels in mice and may have antidepressant effects. Oregano oil has various antioxidant and antibacterial properties that are likely due to its active ingredient, carvacrol One study showed that ingesting carvacrol promoted dopamine production and provided antidepressant effects in mice as a result Another study in mice found that oregano extract supplements inhibited the deterioration of dopamine and induced positive behavioral effects While these animal studies are encouraging, more human studies are warranted to determine whether oregano oil provides similar effects in people.
Summary Oregano oil supplements have been proven to increase levels of dopamine and produce antidepressant effects in mice. Human-based research is lacking. Magnesium plays a vital role in keeping your body and mind healthy. Magnesium and its antidepressant qualities are still not fully understood, but there is evidence that magnesium deficiency may contribute to decreased dopamine levels and an increased risk of depression 29 , Currently, research on the effects of magnesium supplements on dopamine levels is limited to animal studies.
Summary Most research is limited to animal studies, but magnesium deficiency may contribute to low dopamine levels. Taking a magnesium supplement can help. Green tea has long been touted for its antioxidant properties and nutrient content.
It also contains the amino acid L-theanine, which directly affects your brain Multiple studies have shown that L-theanine increases dopamine production, thus causing an antidepressant effect and enhancing cognitive function 32 , 33 , Additionally, studies suggest that both green tea extract and frequent consumption of green tea as a beverage can increase dopamine production and are associated with lower rates of depressive symptoms 35 , Summary Green tea contains the amino acid L-theanine, which has been shown to increase dopamine levels.
Vitamin D has many roles in your body, including the regulation of certain neurotransmitters like dopamine One study showed decreased dopamine levels in vitamin-D-deprived mice and improved levels when supplementing with vitamin D3 Preliminary animal studies show promise, but human studies are needed to better understand the relationship between vitamin D and dopamine in people.
Summary While animal studies show promise, human studies are needed to see if vitamin D supplements increase dopamine levels in those with vitamin D deficiency. Fish oil supplements primarily contain two types of omega-3 fatty acids : eicosapentaenoic acid EPA and docosahexaenoic acid DHA.
Many studies have discovered that fish oil supplements have antidepressant effects and are linked to improved mental health when taken regularly 39 , 40 , Summary Fish oil supplements may increase dopamine levels in the brain and prevent and treat depressive symptoms.
Studies have found that caffeine can boost cognitive performance, including by enhancing the release of neurotransmitters, such as dopamine 43 , 44 , However, your body can develop a tolerance to caffeine, meaning it learns how to process increased amounts.
Therefore, you may need to consume more caffeine than you did before to experience the same effects Summary Caffeine is linked to increased dopamine levels by enhancing dopamine receptors in your brain.
Over time, you may develop a greater tolerance for caffeine and may need to increase your consumption to have the same effects. Ginseng has been used in traditional Chinese medicine since ancient times.
Studies have shown that ginseng may enhance brain skills, including mood, behavior and memory 47 , It has also been suggested that certain components in ginseng, such as ginsenosides, are responsible for the increase of dopamine in the brain and for beneficial effects on mental health, including cognitive function and attention One study on the effects of Korean red ginseng on attention deficit hyperactivity disorder ADHD in children observed that lower levels of dopamine were associated with symptoms of ADHD.
The children involved in the study received 2, mg of Korean red ginseng daily for eight weeks. At the end of the study, the results showed that ginseng improved attention in children with ADHD However, further studies are needed to draw definite conclusions about the extent to which ginseng enhances dopamine production and brain function in humans.
Summary Many animal and test-tube studies have shown an increase in dopamine levels after supplementing with ginseng. Ginseng may increase dopamine levels in humans, especially those with ADHD, but more research is needed.
Berberine is an active component present in and extracted from certain plants and herbs. It has been used in traditional Chinese medicine for years and has recently gained popularity as a natural supplement.
Several animal studies show that berberine increases dopamine levels and may help fight depression and anxiety 54 , 55 , 56 , Currently, there is no research on the effects of berberine supplements on dopamine in humans.
Therefore, more research is needed before recommendations can be made. Summary Many studies show that berberine increases dopamine levels in the brains of mice. However, further research is needed to fully understand the effects of berberine and dopamine levels in humans.
Generally, the risk associated with taking the above supplements is relatively low. They all have good safety profiles and low toxicity levels in low-to-moderate dosages. The primary possible side effects of some of these supplements are related to digestive symptoms, such as gas, diarrhea, nausea or stomach pain.
Headaches, dizziness and heart palpitations have also been reported with certain supplements, including ginkgo, ginseng and caffeine 58 , 59 , Dopamine is an important chemical in your body that influences many brain-related functions, such as mood, motivation and memory.
Generally, your body regulates dopamine levels well on its own, but some medical conditions and diet and lifestyle choices can lower your levels. Along with eating a balanced diet , many possible supplements may help boost dopamine levels , including probiotics, fish oil, vitamin D, magnesium, ginkgo and ginseng.
Each of the supplements on this list has a good safety profile when used properly. However, some supplements may interfere with certain prescription or over-the-counter medications.

Information from the second question of the manipulation check was evaluated qualitatively. Previous research suggests that male and female students may differ in their use of caffeine for NE Franke et al. We therefore concluded that in spite of the randomization error under-representation of men in condition B the randomization process was successful overall.
The group mean responses to the question about what percentage of university students in Germany used caffeine pills for NE on at least one occasion were as follows: group A fivefold overestimate of prevalence, i.
This finding is illustrated in Figure 1. Thirty-one participants Descriptive statistics for all variables are summarized in Table 1. The low variance inflation factor of 1. The structural model with regression weights for relationships between variables bootstrapped CI s in Table 2 and determination coefficients for variables is displayed in Figure 2A.
TABLE 2. FIGURE 2. The Prototype Willingness Model Gibbons et al. for paths and the illustration of experimental effects B. We therefore concluded that provision of experimentally manipulated information about peer behavior did not produce group mean differences in any of the investigated variables.
This means that in our sample provision of information about prevalence of use of caffeine pills for NE decreased the predictive value of attitude to use of caffeine for NE on willingness to do so. Testing predictions derived from a theory of behavior minimizes the risk of reporting random effects and overestimating relationships; it is thus a suitable strategy for uncovering the psychological mechanisms underlying behavior and behavior change Zelli et al.
On the basis of this result and previous findings on the effects of peer pressure Sattler et al. Interestingly, in this investigation attitude was a much weaker predictor of intention than in other investigations of problematic consumption behavior e.
The most likely explanation for this is that we chose to measure a very specific intention, i. In particular, we recommend research into the conceptual relationship between willingness and intention empirical data from many studies based on the PWM suggest that the two constructs are fairly highly correlated, c.
Todd et al. We think that willingness to engage in a given behavior may be much more sensitive to changes in motivational predictors e. A fundamental assumption of the PWM is that willingness is the basis of socially reactive, i. Structural equation modeling modeling enabled us to estimate correlations between the PWM variable past behavior and the residual variance in willingness and intention with respect to the relevant behavior.
These unidentified variables have a considerable impact on willingness and intention to use specific neuroenhancers and perhaps NE more generally.
Candidates for these thus far unidentified variables might be found in the psychological roots of NE behavior and perhaps in the goals at which NE is directed.
The PWM variable past behavior was linked to social norm and attitude but had almost no relationship with user prototype. In the terminology of the PWM the basis for socially reactive use of caffeine pills to improve academic performance seems to be the strong influence of attitude on willingness; user prototype appears to play little role in socially reactive NE in this instance.
This may be due to our choice of example neuroenhancer, namely caffeine pills. If we assume that university students are better educated than the general population we might expect them to be more resistant to social influences and generally less prone to unplanned, socially reactive behavior and hence that user prototype would be a stronger predictor of NE behavior in other samples and in relation to other substances.
We suggest that receiving new information about peer prevalence might weaken the association between attitude to a given behavior and willingness to engage in it. This finding reinforces our main contention, shared by other authors Wolff and Brand, ; Wolff et al. The limitations of this research should be acknowledged.
First of all, psychological theories such as the PWM are intended to predict behavior. We have neither predicted a temporal relationship e. We experimentally manipulated one variable information about prevalence and were thus able to make causal inferences related to this manipulation providing information about prevalence reduced the influence of attitude to NE on willingness to engage in it.
We are, however, unable to draw conclusions about the validity of theoretical assumptions about the causal relationships between other variables e. Longitudinal studies are needed to draw conclusions about the consequences of changes in motivational determinants.
Another limitation of our study is that our analyses were based on data from an ad hoc sample of university students which may not have been representative of the population. Although, we are optimistic that our findings are valid further studies are needed to corroborate our findings and interpretation.
We hope that future research will be theoretically informed, seeking to address research questions derived from and relevant to psychological theory. By taking this kind of approach we have shown that information about the prevalence of a behavior amongst peers — in this case use of NE to improve academic performance — might have a deterrent effect via attitude to NE and willingness to engage in NE.
The approach described in this study might be particularly useful for the designers of public health campaigns. RB developed this research question. HK conducted the empirical part of the study as a part of her bachelor thesis.

Nootropics are agents proven to bolster cognitive function and enhance brain efficiency. They primarily affect neurotransmitters like dopamine and serotonin when it comes to motivation. Dopamine, the neurotransmitter linked to pleasure and rewards, significantly influences our levels of motivation by governing mood, attention, and focus. Nootropics can either spur dopamine release or inhibit its uptake in synapses, thus enhancing motivation and drive.Caffeine pills for increased motivation -

Abstract Background TeaCrine® is the synthetic version to naturally occurring theacrine 1, 3, 7, 9-tetramethyluric acid found in the leaves of Camellia kucha tea plants. Methods Twelve resistance-trained men participated in a randomized, double-blind, cross-over designed study.
Results There were no differences between groups for 1RM, RTF, and power in the bench press and squat exercises. Background The ergogenic properties of caffeine have spurred the production of caffeine products and caffeine-like compounds.
Procedures This study utilized a randomized, double-blind, cross-over design and consisted of eight separate laboratory visits. Exercise protocol All exercises were performed using a kg Olympic bar with proper technique in accordance to Baechle et al. Results Descriptive characteristics Descriptive characteristics of the participants at baseline are provided in Table 1.
Table 1 Descriptive variables and caffeine intake Full size table. Full size image. Table 2 Resistance and rowing performance in each treatment condition Full size table. Table 3 Power and velocity for 1 RM and RTF bench press and squat for each treatment Full size table.
Discussion The present study is the first to examine the efficacy of TeaCrine®, a caffeine-like compound, on maximal muscular strength, endurance, and power performance in resistance trained-men.
Strength Bench press 1RM was 2. Power Peak and mean power and velocity were not significantly different between any of the treatment groups. Rowing There were no significant differences in rowing time trial performance across treatments, disagreeing with previous literature, which has reported increased performance from caffeine consumption [ 39 , 40 ].

About this article. Cite this article Cesareo, K. In the past few years, research on the PWM has accumulated in health psychology and a meta-analysis was published very recently Todd et al.
It is important to note that the meta-analysis did not test the full set of relationships involving PWM variables; it focused on the postulated correlations between prototypes, willingness and intentions and thus corroborated the postulated processes of the social reactive path.
Most importantly the meta-analysis revealed that although willingness and intention are sometimes highly correlated they also act as independent predictors of risk behavior. Willingness explained an additional 4. The postulated correlations between variables in the reasoned pathway have been tested in several other PWM-related studies e.
Astonishingly, however, there is a dearth of empirical analyses of the full set of PWM variables using, e. Neuroenhancement research e. The PWM is a comprehensive psychological theory of behavior that integrates all these variables.
The PWM postulates two interacting pathways of behavioral regulation: the reasoned action path, in which attitudes and norms predict intention the most proximal predictor of behavior and the social reactive path, which integrates information from prototypes, attitudes, and norms to form another proximal predictor of behavior, i.
The PWM thus represents an integrative psychological framework for the study of NE behavior. Use of drugs for NE carries health risks Schermer et al. A third group received no information about prevalence and served as a control group condition C.
We investigated use of caffeine pills specifically. Caffeine is available in over-the-counter products and in higher doses as a prescription drug. Our second research question was based on the assumption that university students would have some sort of subjective perception of the prevalence of NE in their peer group and that this perception would shape their thinking about NE.
We explored whether experimentally manipulating information about the prevalence of use of caffeine pills for NE amongst peers high prevalence; low prevalence; no prevalence information would influence the behavioral determinants specified in the PWM attitude, subjective norm, user prototype, willingness, and intention and the associations between these variables and willingness or intention to engage in the target behavior.
This study was conducted online as a factorial survey experiment Jasso, The Questback EFS The questionnaire was presented in German i. The access link was distributed via Facebook and email thus creating a convenience sample drawn from the target population, university students in Germany.
Data collection started in March and ended 3 weeks later in April The study was carried out in accordance with the recommendations of the ethical committee of the University of Potsdam February All participants gave written, informed consent in accordance with the Declaration of Helsinki.
Four hundred and thirty-six university students clicked on the link giving access to our survey. Of these Forty-nine students did not consent to having their data saved and analyzed on the last page, so the responses of participants One year-old participant did not provide information about gender.
When they clicked through to the second page of the online questionnaire participants were randomly assigned to one of the three experimental conditions. Participants in condition A fivefold overestimation of prevalence; Franke et al.
The descriptive facet of this PWM variable was captured using three statements see Hammer and Vogel, to which participants responded using a six-point, i.
Higher values represented a more positive attitude toward use of caffeine pills for NE. The mean score from these five items was used for statistical analyses.
Participants were asked to imagine what a typical user of caffeine pills — perhaps a fellow student from their university — might be like see Gibbons et al. Participants were asked to read two hypothetical scenarios and rate their willingness to use NE in each see Gibbons et al.
You have the option of taking caffeine pills to dispel your fatigue and thus revise more effectively. Participants were asked to provide their age and gender, and state whether they were currently enrolled as a university student.
Participants were also asked whether they thought there was anything suspicious, wrong, or strange about the questionnaire, and in particular if they thought they had been manipulated by the ways in which we gave or asked for information earlier in the questionnaire.
The last page of the questionnaire provided full information about the goals and procedure for the study. This included a statement of the actual estimated prevalence of use of caffeine pills for NE among university students i.
Participants had to tick response boxes to indicate that they had read and understood this information and consented to the confidential storage and analysis of their data for scientific use by the Division of Sport and Exercise Psychology of the University of Potsdam.
SPSS Structural equation modeling SEM with Amos A SEM multigroup moderation approach Byrne, was used to investigate experimentally induced alterations in the relative predictive power of PWM predictors of willingness and intention Lowry and Gaskin, These tests were carried out with a program created by Gaskin which calculates z -scores based on critical ratio tests of the multigroup model and unstandardized estimates.
Information from the second question of the manipulation check was evaluated qualitatively. Previous research suggests that male and female students may differ in their use of caffeine for NE Franke et al.

| Motivation And Well-Being | Additionally, one study in people with irritable bowel syndrome IBS found that those who received probiotic supplements had a reduction in depressive symptoms, compared to those who received a placebo While probiotic research is rapidly evolving, further studies are needed to fully understand the effect of probiotics on mood and dopamine production. You can add probiotics to your diet by consuming fermented food products, such as yogurt or kefir , or taking a dietary supplement. Summary Probiotics are important not only for digestive health but also for many functions in your body. Mucuna pruriens is a type of tropical bean native to parts of Africa, India and Southern China The most significant compound found in Mucuna pruriens is an amino acid called levodopa L-dopa. L-dopa is needed for your brain to produce dopamine For example, one study found that taking 5 grams of Mucuna pruriens powder for three months increased dopamine levels in infertile men Another study found that Mucuna pruriens had an antidepressant effect in mice due to an increase in dopamine production Summary Mucuna pruriens has been shown to be effective in increasing dopamine levels in both humans and animals and may have an antidepressant effect. Ginkgo biloba is a plant native to China that has been used for hundreds of years as a remedy for various health conditions. Although research is inconsistent, ginkgo supplements may improve mental performance, brain function and mood in certain people. Some studies have found that supplementing with Ginkgo biloba in the long term increased dopamine levels in rats, which helped improve cognitive function, memory and motivation 18 , 19 , One test-tube study showed that Ginkgo biloba extract appeared to increase dopamine secretion by reducing oxidative stress These preliminary animal and test-tube studies are promising. However, further research is needed before scientists can determine if Ginkgo biloba also increases dopamine levels in humans. Summary Ginkgo biloba supplements have been shown to increase dopamine levels in animal and test-tube studies. However, further research is needed to conclude whether ginkgo is successful in increasing levels in humans. Curcumin is the active ingredient in turmeric. Curcumin comes in capsule, tea, extract and powdered forms. One small, controlled study found that taking 1 gram of curcumin had similar effects as that of Prozac on improving mood in people with major depressive disorder MDD There is also evidence that curcumin increases dopamine levels in mice 24 , Summary Curcumin is the active ingredient in turmeric. It has been shown to increase dopamine levels in mice and may have antidepressant effects. Oregano oil has various antioxidant and antibacterial properties that are likely due to its active ingredient, carvacrol One study showed that ingesting carvacrol promoted dopamine production and provided antidepressant effects in mice as a result Another study in mice found that oregano extract supplements inhibited the deterioration of dopamine and induced positive behavioral effects While these animal studies are encouraging, more human studies are warranted to determine whether oregano oil provides similar effects in people. Summary Oregano oil supplements have been proven to increase levels of dopamine and produce antidepressant effects in mice. Human-based research is lacking. Magnesium plays a vital role in keeping your body and mind healthy. Magnesium and its antidepressant qualities are still not fully understood, but there is evidence that magnesium deficiency may contribute to decreased dopamine levels and an increased risk of depression 29 , Currently, research on the effects of magnesium supplements on dopamine levels is limited to animal studies. Summary Most research is limited to animal studies, but magnesium deficiency may contribute to low dopamine levels. Taking a magnesium supplement can help. Green tea has long been touted for its antioxidant properties and nutrient content. It also contains the amino acid L-theanine, which directly affects your brain Multiple studies have shown that L-theanine increases dopamine production, thus causing an antidepressant effect and enhancing cognitive function 32 , 33 , Additionally, studies suggest that both green tea extract and frequent consumption of green tea as a beverage can increase dopamine production and are associated with lower rates of depressive symptoms 35 , Summary Green tea contains the amino acid L-theanine, which has been shown to increase dopamine levels. Vitamin D has many roles in your body, including the regulation of certain neurotransmitters like dopamine One study showed decreased dopamine levels in vitamin-D-deprived mice and improved levels when supplementing with vitamin D3 Preliminary animal studies show promise, but human studies are needed to better understand the relationship between vitamin D and dopamine in people. Summary While animal studies show promise, human studies are needed to see if vitamin D supplements increase dopamine levels in those with vitamin D deficiency. Fish oil supplements primarily contain two types of omega-3 fatty acids : eicosapentaenoic acid EPA and docosahexaenoic acid DHA. Most importantly the meta-analysis revealed that although willingness and intention are sometimes highly correlated they also act as independent predictors of risk behavior. Willingness explained an additional 4. The postulated correlations between variables in the reasoned pathway have been tested in several other PWM-related studies e. Astonishingly, however, there is a dearth of empirical analyses of the full set of PWM variables using, e. Neuroenhancement research e. The PWM is a comprehensive psychological theory of behavior that integrates all these variables. The PWM postulates two interacting pathways of behavioral regulation: the reasoned action path, in which attitudes and norms predict intention the most proximal predictor of behavior and the social reactive path, which integrates information from prototypes, attitudes, and norms to form another proximal predictor of behavior, i. The PWM thus represents an integrative psychological framework for the study of NE behavior. Use of drugs for NE carries health risks Schermer et al. A third group received no information about prevalence and served as a control group condition C. We investigated use of caffeine pills specifically. Caffeine is available in over-the-counter products and in higher doses as a prescription drug. Our second research question was based on the assumption that university students would have some sort of subjective perception of the prevalence of NE in their peer group and that this perception would shape their thinking about NE. We explored whether experimentally manipulating information about the prevalence of use of caffeine pills for NE amongst peers high prevalence; low prevalence; no prevalence information would influence the behavioral determinants specified in the PWM attitude, subjective norm, user prototype, willingness, and intention and the associations between these variables and willingness or intention to engage in the target behavior. This study was conducted online as a factorial survey experiment Jasso, The Questback EFS The questionnaire was presented in German i. The access link was distributed via Facebook and email thus creating a convenience sample drawn from the target population, university students in Germany. Data collection started in March and ended 3 weeks later in April The study was carried out in accordance with the recommendations of the ethical committee of the University of Potsdam February All participants gave written, informed consent in accordance with the Declaration of Helsinki. Four hundred and thirty-six university students clicked on the link giving access to our survey. Of these Forty-nine students did not consent to having their data saved and analyzed on the last page, so the responses of participants One year-old participant did not provide information about gender. When they clicked through to the second page of the online questionnaire participants were randomly assigned to one of the three experimental conditions. Participants in condition A fivefold overestimation of prevalence; Franke et al. The descriptive facet of this PWM variable was captured using three statements see Hammer and Vogel, to which participants responded using a six-point, i. Higher values represented a more positive attitude toward use of caffeine pills for NE. The mean score from these five items was used for statistical analyses. Participants were asked to imagine what a typical user of caffeine pills — perhaps a fellow student from their university — might be like see Gibbons et al. Participants were asked to read two hypothetical scenarios and rate their willingness to use NE in each see Gibbons et al. You have the option of taking caffeine pills to dispel your fatigue and thus revise more effectively. Participants were asked to provide their age and gender, and state whether they were currently enrolled as a university student. Participants were also asked whether they thought there was anything suspicious, wrong, or strange about the questionnaire, and in particular if they thought they had been manipulated by the ways in which we gave or asked for information earlier in the questionnaire. The last page of the questionnaire provided full information about the goals and procedure for the study. This included a statement of the actual estimated prevalence of use of caffeine pills for NE among university students i. Participants had to tick response boxes to indicate that they had read and understood this information and consented to the confidential storage and analysis of their data for scientific use by the Division of Sport and Exercise Psychology of the University of Potsdam. SPSS Structural equation modeling SEM with Amos A SEM multigroup moderation approach Byrne, was used to investigate experimentally induced alterations in the relative predictive power of PWM predictors of willingness and intention Lowry and Gaskin, These tests were carried out with a program created by Gaskin which calculates z -scores based on critical ratio tests of the multigroup model and unstandardized estimates. Information from the second question of the manipulation check was evaluated qualitatively. Previous research suggests that male and female students may differ in their use of caffeine for NE Franke et al. We therefore concluded that in spite of the randomization error under-representation of men in condition B the randomization process was successful overall. The group mean responses to the question about what percentage of university students in Germany used caffeine pills for NE on at least one occasion were as follows: group A fivefold overestimate of prevalence, i. This finding is illustrated in Figure 1. Thirty-one participants Descriptive statistics for all variables are summarized in Table 1. The low variance inflation factor of 1. The structural model with regression weights for relationships between variables bootstrapped CI s in Table 2 and determination coefficients for variables is displayed in Figure 2A. TABLE 2. FIGURE 2. The Prototype Willingness Model Gibbons et al. for paths and the illustration of experimental effects B. We therefore concluded that provision of experimentally manipulated information about peer behavior did not produce group mean differences in any of the investigated variables. This means that in our sample provision of information about prevalence of use of caffeine pills for NE decreased the predictive value of attitude to use of caffeine for NE on willingness to do so. Testing predictions derived from a theory of behavior minimizes the risk of reporting random effects and overestimating relationships; it is thus a suitable strategy for uncovering the psychological mechanisms underlying behavior and behavior change Zelli et al. On the basis of this result and previous findings on the effects of peer pressure Sattler et al. Interestingly, in this investigation attitude was a much weaker predictor of intention than in other investigations of problematic consumption behavior e. The most likely explanation for this is that we chose to measure a very specific intention, i. In particular, we recommend research into the conceptual relationship between willingness and intention empirical data from many studies based on the PWM suggest that the two constructs are fairly highly correlated, c. Todd et al. We think that willingness to engage in a given behavior may be much more sensitive to changes in motivational predictors e. A fundamental assumption of the PWM is that willingness is the basis of socially reactive, i. Structural equation modeling modeling enabled us to estimate correlations between the PWM variable past behavior and the residual variance in willingness and intention with respect to the relevant behavior. These unidentified variables have a considerable impact on willingness and intention to use specific neuroenhancers and perhaps NE more generally. Candidates for these thus far unidentified variables might be found in the psychological roots of NE behavior and perhaps in the goals at which NE is directed. The PWM variable past behavior was linked to social norm and attitude but had almost no relationship with user prototype. In the terminology of the PWM the basis for socially reactive use of caffeine pills to improve academic performance seems to be the strong influence of attitude on willingness; user prototype appears to play little role in socially reactive NE in this instance. This may be due to our choice of example neuroenhancer, namely caffeine pills. If we assume that university students are better educated than the general population we might expect them to be more resistant to social influences and generally less prone to unplanned, socially reactive behavior and hence that user prototype would be a stronger predictor of NE behavior in other samples and in relation to other substances. We suggest that receiving new information about peer prevalence might weaken the association between attitude to a given behavior and willingness to engage in it. This finding reinforces our main contention, shared by other authors Wolff and Brand, ; Wolff et al. The limitations of this research should be acknowledged. First of all, psychological theories such as the PWM are intended to predict behavior. We have neither predicted a temporal relationship e. We experimentally manipulated one variable information about prevalence and were thus able to make causal inferences related to this manipulation providing information about prevalence reduced the influence of attitude to NE on willingness to engage in it. We are, however, unable to draw conclusions about the validity of theoretical assumptions about the causal relationships between other variables e. Longitudinal studies are needed to draw conclusions about the consequences of changes in motivational determinants. Another limitation of our study is that our analyses were based on data from an ad hoc sample of university students which may not have been representative of the population. Although, we are optimistic that our findings are valid further studies are needed to corroborate our findings and interpretation. We hope that future research will be theoretically informed, seeking to address research questions derived from and relevant to psychological theory. By taking this kind of approach we have shown that information about the prevalence of a behavior amongst peers — in this case use of NE to improve academic performance — might have a deterrent effect via attitude to NE and willingness to engage in NE. The approach described in this study might be particularly useful for the designers of public health campaigns. RB developed this research question. HK conducted the empirical part of the study as a part of her bachelor thesis. RB and HK jointly re-analyzed the data, adjusted and broadened the chain of arguments, and then cooperatively wrote this report. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. The reviewer Christopher Fullerton and handling Editor declared their shared affiliation, and the handling Editor states that the process nevertheless met the standards of a fair and objective review.

There is a wide variation in how sensitive people are to the effects of caffeine and how fast they metabolize it. These factors can make it difficult to say precisely how much caffeine is too much for one person to consume. Certain conditions tend to make people more sensitive to caffeine, as can other medications. The FDA has cited that mg of caffeine is safe for healthy adults, but they have not set a recommended level for children. Many still discourage the consumption of caffeine and other stimulants by children or adolescents including the American Academy of Pediatrics. People who should avoid or limit caffeine include:. Although it is rare, it is possible for someone to overdose on caffeine pills. A toxic dose of caffeine is considered to be five or more grams. Caffeine pills and other over-the-counter supplements, which are typically used to combat fatigue, generally contain mg caffeine per tablet. Ingesting too many caffeine pills may cause fatal caffeine intoxication. Symptoms of caffeine overdose may include:. It may not be possible to become addicted to caffeine pills, but once someone develops a dependency on caffeine, they can experience withdrawal symptoms. Suddenly stopping consuming caffeine pills, after taking them regularly, can cause individuals to experience symptoms of caffeine withdrawal such as:. Individuals who consume caffeine pills daily but want to cut back should do so gradually. It is never a good idea to stop medications suddenly as it can send the body into a state of shock. Unlike opioid or alcohol withdrawal, caffeine withdrawal is not considered to be particularly dangerous. However, if someone is dependent on other substance in addition to caffeine, their caffeine dependence may influence the way they experience withdrawal from one or both substances. In these cases, the additional help of an inpatient treatment program may be required. While withdrawing from caffeine may not be dangerous, it can be unpleasant and talking to a healthcare professional can help you figure out how to cut back.
