Both caffeinated and Guaranna energy drinks contain high concentrations of sugars, the effects of which have been functioh researched.

With regard to mood, cognitivf studies reported mixed interactive effects of glucose and caffeine, 11 Guaranx, 14 3 did not report any andd Guarana and cognitive function, 41012 and 1 cogintive not assess mood.

Finally, the interactive effects of glucose and caffeine on memory tasks have cognitice more consistent.

Guatana is one of the most common ingredients in energy drinks, dietary supplements, and noncaffeinated energy drinks.

One study reported no interactive effect of the substances on attention and memory performance, 11 while the other reported that taurine attenuated caffeine-induced decreases in selective attention reaction time. The combination also did not influence sleep-deprivation-induced impairments in movement efficiency or accuracy on a fine motor task, but it should be noted that caffeine alone also did not improve performance on the motor task.

Nevertheless, it is premature to draw definitive conclusions on the basis of only 2 controlled studies. L -theanine is an amino acid that is structurally related to glutamate yet is purported to produce relaxant effects.

In addition to being a common ingredient in energy drinks, L -theanine occurs naturally in tea. Thus, comparatively more controlled studies have assessed the mood and cognitive effects of L -theanine than the effects of some other energy drink ingredients.

Ginseng Panax ginseng is a botanical ingredient that has been used for centuries in Chinese medicine. The mood and cognitive effects of acute ginseng administration have been investigated in several studies.

With regard to mood effects, the largest effect sizes were seen for maintaining energy during cognitively demanding tasks. There has been only 1 study of ginseng in combination with caffeine administered in the form of guarana.

In general, there were no interactions between the substances on measures of mood, attention, or memory, although the combination did produce a prolonged decrease in errors on 1 of 2 working memory tasks.

However, despite the overall lack of interactions between the 2 substances, this does not rule out the possibility of interactive effects, since the caffeine content of the guaraná extract was very low. Thus, future studies must investigate interactions between ginseng and doses of caffeine comparable to those present in energy drinks.

A number of energy drink ingredients have been studied in isolation for mood and performance effects. Although these ingredients have not been studied in combination with caffeine, some of them show promising effects alone and deserve further study in combination with caffeine.

Guarana is a plant native to South America, where it has a long history of use for its supposed stimulatory properties. The first study reported no effects of any treatments on mood, attention, memory, or other psychomotor tasks in healthy young adults.

While it may be presumed that the effects of guarana in combination with caffeine might be similar to the effects of an equivalent dose of caffeine, some researchers have suggested that other chemicals present in guarana are responsible for its observed behavioral effects; this is because the caffeine levels of the guarana doses studied were too low to produce the reported effects.

A recent review 42 concluded that the cognitive effects of caffeine-containing herbal extracts such as guarana often differ from those of caffeine, suggesting an involvement of other plant chemicals. Thus, studies of the other active components of guarana in combination with caffeine are warranted.

Tyrosine is a precursor of catecholamine hormones and neurotransmitters, including adrenaline, noradrenaline, and dopamine, which are integrally involved in regulating mood and behavior.

Phenylalanine is a tyrosine precursor. The majority of research studies with tyrosine have focused on its beneficial effects under stressful conditions.

Reactions to acute stress involve activation of the peripheral and central nervous systems and the release of catecholamines, which depletes catecholamine stores, causing mood and cognitive impairments. This is surprising, given the evidence that tyrosine improves mood and cognition in fatigued and acutely stressed individuals, the target consumers of energy products.

Gingko biloba is used in traditional medical systems. Most research into the effects of Gingko biloba extract on mood and cognition has focused on its long-term use and potential protective effect against cognitive decline. The results of these clinical studies have been mixed, with some positive findings 62— 66 and some negative findings 67— 69 reported.

Similarly, reviews and meta-analyses have drawn different conclusions, with some supporting 7071 and others opposing 72— 74 the efficacy of gingko in counteracting age- and disease-related cognitive decline.

Discrepancies between studies reporting positive and negative findings for gingko may be explained by differences in treatment duration and subject populations: studies reporting null effects were conducted over shorter periods maximum 6 years follow-up in subjects who, in some cases, were already cognitively impaired.

They found that those who reported use of gingko showed reduced global cognitive decline compared with those who used no treatments. However, the results should be interpreted with caution, since the study employed a retrospective cohort design and other confounding variables could have influenced the findings.

The acute and short-term effects of gingko on mood and cognitive performance in young healthy subjects have been investigated in several controlled studies. As for its effects on mood, gingko was reported to improve well-being 75 but not subjective alertness.

In summary, the long-term use of gingko has failed to show clear effects on cognitive decline, and the acute and short-term effects of gingko administration on mood and performance have been inconsistent.

A recent review 87 of all placebo-controlled studies of gingko in both healthy and cognitively impaired individuals concluded that the most prominent effects of gingko were observed during complex tasks rather than simple ones, with the greatest effects observed during tests of fluid intelligence and attention.

Herbal extracts contain other phytochemicals, including other methylxanthines e. In placebo-controlled studies, 8990 theobromine produced few effects on mood and attention aside from increases in feeling the effects of drugs.

Theophylline, another methylxanthine present in herbal extracts, has been reported to improve memory speed, information processing, and attention in healthy adults 9293 and to improve attention in elderly subjects.

Energy drinks often contain vitamins e. These vitamins and minerals are essential for effective functioning of the nervous system, and deficiencies have been linked to cognitive deficits and mood disorders.

It is thought that vitamin and mineral supplements are most likely to benefit individuals who are deficient in a given micronutrient at the outset, and thus studies of vitamin and mineral supplements and their influence on mood and cognition must consider the baseline nutritional status of subjects.

When converted to phosphocreatine, creatine acts as a high-energy source during intense physical or mental exercise, and a limited number of studies have reported beneficial effects of acute or short-term creatine administration on cognitive performance.

Two studies reported that creatine improved mood, attention, and complex working memory after short periods of sleep deprivation,and others reported significant improvements in attention and memory performance in well-rested participants.

Citicoline is an intermediate component in the synthesis of phosphatidylcholine, the major phospholipid of cell membranes. It also activates the central cholinergic system, thereby inducing hormone release adrenocorticotrophic hormone, growth hormone, luteinizing hormoneand has been reported to increase brain levels of noradrenaline, dopamine, serotonin, and acetylcholine.

Studies have reported effects on brain activity and energy use that are consistent with increased mental alertness, but no effects on behavioral measures have been reported. L -arginine is involved in 2 important metabolic pathways: nitric oxide production and ammonia detoxification.

It also potently induces the secretion of insulin, growth hormone, and prolactin and the release of catecholamines. Tea Camellia sinensis is a plant native to China, where it has a long history of consumption for medicinal purposes.

The leaves of the plant may be processed in a variety of ways, producing, for example, black, green, or white tea. Green tea extract contains theanine, catechins, and flavonols in addition to caffeine. Tea has been found to benefit cardiovascular health, but its effects on mood and cognition have been less studied.

One study reported that a combination of green tea extract and L -theanine improved selective attention, memory performance, and brain correlates of alertness in individuals with mild cognitive impairment. A later review concluded that green tea consumption was associated with improved cognitive function in aged individuals but could not establish a definitive link.

The mood and cognitive effects of green tea extract in healthy individuals have not been assessed. Carnitine is an essential dietary nutrient that plays a vital role in energy production.

It has been shown to improve mood and cognitive function in individuals with cognitive impairment— and to improve symptoms of depression, but its effects on mood and cognition have not been evaluated in healthy individuals.

L -tryptophan L -Trp and 5-hydroxytryptophan 5-HTP are precursors of serotonin 5-HTa neurotransmitter that plays a central role in behavioral and emotional control.

L -Trp is the least abundant amino acid and must compete with other, more common large amino acids for transport across the blood-brain barrier. In comparison, 5-HTP more readily penetrates the brain,— where it is converted to serotonin, and thus dietary 5-HTP supplements may feasibly enhance brain serotonin levels.

The outbreak was thought to be due to a contaminant in a particular product, and L -Trp was subsequently reapproved inbut there is some evidence of genetic sensitivity to eosinophilia-myalgia syndrome associated with L -Trp.

12 Benefits of Guarana (Plus Side Effects)

Guarana is generally regarded as safe when not combined with other stimulatory agents, such as ephedra. In the current study, the authors evaluated the effects of a multivitamin-guarana preparation on participants who performed a working memory task.

They recruited 20 subjects with an average age of 29 who were randomly assigned to receive Berocca® Performance a multivitamin with guarana , Berocca® Boost a multivitamin without guarana , or a placebo.

Thirty minutes after the treatment, the participants performed a cognitive assessment, and their mood ratings were analyzed immediately before and after the task. Some subjects underwent additional cognitive imaging analysis during the task. The results suggested that people who received the multivitamin containing guarana had significantly better performance, as well as self-rated contentment.

Everyone who received a multivitamin, regardless of whether or not it contained guarana, had increased brain activation in areas associated with attention and memory, with the effect being more significant in those who had taken the guarana preparation. The authors concluded that multivitamins with guarana may benefit both mood and cognitive enhancement.

They added that the results demonstrate that multivitamin preparations with and without guarana may help increase brain activation. More information is needed to confirm these findings.

Many other integrative therapies have been studied for possible benefits on cognitive performance.
