: Protein and mood regulation| Table of Contents | Tryptophan and cortisol are produced through similar mechanisms. Even though it's difficult to measure serotonin levels in the body, the association between a high Trp:LNAA ratio and reduced stress-related symptoms resulting from increased serotonin levels was first supported in by a group of researchers Rosenthal, Generally, proteins are poor in tryptophan in comparison to the other large neutral amino acids Lieberman, However, because whey-derived alpha-lactalbumin is abundant in tryptophan, researchers were curious to see whether or not a diet rich in its consumption had an impact on the Trp:LNAA ratio, the production of the biomarkers serotonin and cortisol, and depressive and stress-related symptoms. Thus, experts throughout the world in the fields of biochemistry, pharmacology, and nutrition produced several high-quality research studies which you can read about below. To assess whether or not whey protein contributed to suppression of cortisol levels, a group of Dutch researchers led by C. The researchers also documented that the stress-vulnerable population had relatively high levels of fatigue, anger, and tension while the stress-invulnerable population has relatively low levels of these stress-associated symptoms. Therefore, the researchers hypothesized that by adding increased alpha-lactalbumin to the diets of the high-stress individuals, they would increase their plasma Trp-LNAA ratio and subsequently, lower cortisol levels while simultaneously increasing levels of serotonin. This would ultimately lead to lower depressive symptoms in the stress-vulnerable population. In contrast, the less stress-vulnerable population who did not consume Alpha-lactalbumin experienced no significant changes in levels of serotonin, cortisol, or stress-associated indicators. In this first blog post of a three-part series, we looked at the basics behind stress, cortisol, serotonin, and whey protein. Berger, M. The Expanded Biology of Serotonin.

Ask Me Anything AMA : Oral Health, Healthspan, and Longevity with Dr. Gil Blander and Ashley One study found that supplementation with an amino acid blend improved symptoms of depression in women. Other studies have shown that increasing protein intake can lead to improvements in mood and overall well-being. One possible explanation for protein's positive effect on mood is its role in the production of neurotransmitters such as serotonin and dopamine. These chemicals are responsible for regulating mood and emotions, and a deficiency in them has been linked to depression and anxiety. Protein contains amino acids, which are the building blocks of neurotransmitters, and increasing protein intake may help to boost their production. Additionally, protein has been shown to have a stabilizing effect on blood sugar levels. Fluctuations in blood sugar can lead to mood swings and feelings of irritability, and a diet high in protein can help to prevent these fluctuations. This may be particularly beneficial for individuals with mood disorders, as they may be more sensitive to changes in blood sugar levels. Protein is important not only for emotional well-being, but also for cognitive function. Studies have shown that low protein intake can impair cognitive performance, while adequate protein intake is important for maintaining brain health. This is because protein is required for the production of neurotransmitters that are involved in learning and memory. In addition to its role in neurotransmitter production, protein also helps to regulate blood sugar levels. This is important for cognitive function because the brain relies on a steady supply of glucose for energy. When blood sugar levels fluctuate, it can lead to cognitive impairment and difficulty concentrating. Therefore, consuming adequate amounts of protein can help to maintain stable blood sugar levels and support optimal brain function. There are many foods that are high in protein and can help to boost your mood naturally. Some top sources include lean meats, poultry, fish, eggs, dairy products, soy products, and legumes such as beans and lentils. Incorporating a variety of these protein-rich foods into your diet can help to improve emotional well-being. In addition to the protein content, some of these foods also contain other nutrients that can positively impact mood. For example, fish is high in omega-3 fatty acids, which have been linked to lower rates of depression and anxiety. Dairy products contain tryptophan, an amino acid that helps to produce serotonin, a neurotransmitter that regulates mood and sleep. It's important to note that while protein can be beneficial for mood, it's not a cure-all. Other factors such as exercise, sleep, and stress management also play a role in emotional well-being. Additionally, some people may have dietary restrictions or preferences that limit their intake of certain protein sources. Consulting with a healthcare professional or registered dietitian can help to create a personalized nutrition plan that supports both physical and mental health. It is clear that adequate protein intake is essential for supporting mental health. Consuming sufficient protein helps to regulate neurotransmitters, hormones, and enzymes in the body that are critical for emotional well-being. Low protein intake has been shown to have negative impacts on mood and cognitive function. If you are looking to incorporate more quality protein into your diet for better mood, there are several strategies you can try. First, aim to eat a protein-rich food at every meal, such as eggs for breakfast or chicken for lunch. Second, try swapping out high-carbohydrate snacks for protein-based snacks, such as nuts, cheese, or Greek yogurt. Finally, consider adding a protein supplement to your diet if you struggle to meet your daily protein needs through whole foods alone. While whole food sources of protein are preferred, protein supplements can be a convenient way to boost protein intake. Some studies suggest that protein supplements may be effective in enhancing mood, especially in people with mood disorders. However, more research is needed in this area to fully understand the impact of protein supplements on emotional well-being. Veganism is a growing trend, and many people are turning to plant-based sources of protein. While animal sources of protein tend to be more complete and easier to digest, there are many plant-based proteins that can be incorporated into a vegan diet. Some top sources include quinoa, tofu, lentils, and nuts. While more research is needed, some studies suggest that plant-based diets may have positive impacts on emotional well-being. If you are looking to optimize your protein intake for improved emotional well-being, there are several key factors to consider. First, aim to consume a variety of protein sources to ensure you are getting all essential amino acids. Second, pay attention to the quality of the protein you are consuming — lean sources of protein such as skinless chicken breast or tofu are preferable to processed meats or sugary protein bars. Finally, be aware of how much protein you are consuming — while a high-protein diet can have many benefits, consuming too much protein can put stress on the kidneys and liver. As we have seen, protein plays a vital role in supporting emotional well-being. From regulating neurotransmitters to improving cognitive function, adequate protein intake is essential for maintaining optimal mental health. By incorporating protein-rich foods into your diet and keeping these key principles in mind, you can support your emotional well-being and improve your overall quality of life. icon-X Close menu.

| Whey Protein's Impact on Mood and Stress | If you are experiencing symptoms of anxiety, irritability, ADHD, or mood swings, then balancing your blood sugar is essential. Blood sugar swings, both high and low, can cause any of these symptoms. The best way to balance your blood sugar is through diet. You want to combine protein, fat, complex carbs, and fiber at EVERY meal. This is where we circle back to the importance of carbohydrates. Complex carbs such as whole grain bread, brown rice, quinoa, and oats just to name a few take longer to digest, and therefore turn to sugar, in your bodies. This helps to prevent your blood sugar from rising too quickly. Eating these with protein, fats, and fiber also help slow the release of sugars into your bloodstream, allowing your levels and your mood to stay at a more stable level. Protein is especially important for this purpose. The slower they turn into sugar what becomes your energy , the more stable your blood sugar levels will stay. You also want to eat regularly to avoid your blood sugar from dropping too low. Aim for 3 meals and 2 snacks each day spaced out into hour intervals or small meals. Your mental health is so much more than just your emotions. Dehydration can affect cognitive function and mood. Even mild dehydration can trigger feelings of fatigue and irritability. Therefore, it is vital to maintain proper hydration by consistently drinking an adequate amount of water throughout the day to support good mental health.

| Top bar navigation | Researchers are exploring the correlation between sugar and depression, and have theorized that a protein called BDNF may be the link. BDNF plays an important part in the maintenance, growth and differentiation of nerve cells in the brain. Sugar suppress the activity of BDNF, which is typically already low in people who have depression. Increasing your intake of protein can help control your sweet tooth and stabilize blood sugar. Protein bars, for instance, can be an effective snacking strategy to keep you satisfied between meals, however, pay attention to the sugar content in protein bars , as some protein bars can contain as much added sugar as a cookie. Protein, as a macronutrient, includes foods that are typically high in iron. Low iron can cause anemia, and is the most common nutritional deficiency in the world. Anemia can leave you feeling fatigued, irritable and disengaged. You may feel unmotivated or unable to sustain physical activity for long periods of time, which can contribute to feelings of depression. Treating anemia will improve your mood and make it easier to function. Ljungberg T, Bondza E, Lethin C. Evidence of the importance of Dietary Habits regarding depressive symptoms and Depression.

Neuroscientist: TRY IT FOR 1 DAY! You Won't Regret It! Habits of The Ultra Wealthy for 2023Protein and mood regulation -
Dietary intakes of the study population among tertiles of plant and animal proteins are presented in Table 2. Participants in the highest tertile of plant protein had a higher intake of whole grains, vegetables, energy, protein, carbohydrate, total fiber, vitamin A, thiamine, vitamin C, calcium, magnesium, potassium, zinc, and iron and lower intakes of total fat and vitamin B12 compared with those in the lowest tertile.
We did a further investigation to see if the tertiles overlap. Frequency analysis showed that only 5. Participants in the top tertile of animal protein consumed more dairy, meats, energy, protein, total fat, vitamin A, vitamin B12, calcium, magnesium, potassium, zinc, and iron and consumed a lower amount of fruits and dietary fiber.
Moreover, there was no significant difference in the consumption of Vitamin B6, fruits, dairy, legumes, and nuts across tertiles of plant protein and intakes of carbohydrate, Thiamine, Vitamin B6, Vitamin C, whole grains, vegetables, legumes, and nuts among animal protein tertiles.
After controlling for potential confounders comprising age, energy intake, physical activity, number of deliveries, socioeconomic status, supplemented use, marital status, educational level, BMI, and DII, the association between depression OR: 2. lowest animal protein tertiles remained significant.
The present study suggests that poultry and dairy products are the most important contributors to animal protein intake in a representative sample of the Iranian population. While rice and legumes were the most important contributors to plant protein intake. Our findings indicated that a higher animal protein intake is associated with an increased risk of depression, anxiety, and stress in adult women.
However, there was no significant association between a high plant protein intake and the mentioned mental disorders. Mainstream medicine views mental disorders as a result of neurochemical imbalances, for instance, depression is often viewed as a serotonin imbalance, and new anti-depressants are prescribed to target the serotonin network [ 24 ].
Another primary neurotransmitter is GABA, a lack of which has been linked to anxiety. Thus many drugs that counter anxiety do so by stimulating GABA release [ 25 ].
Nutrition can play a vital role in the pathophysiology and management of psychiatric disorders by affecting the regulation of neurotransmitters.
Certain amino acids especially tryptophan, tyrosine, and phenylalanine found in high-quality protein sources are known to be the main precursors of these neurotransmitters [ 26 ]. It was also found that the rate of brain serotonin synthesis depends on the concentrations of tryptophan in the brain [ 27 ].
Rosier et al. revealed that a dietary intervention with low levels of phenylalanine and tyrosine would cause a rapid lowering of mood in patients who recovered from depression [ 28 ]. In this study, we found that consuming more animal protein is associated with an increased risk of psychiatric disorders.
There is some evidence that could justify our findings. Tryptophan is the primary precursor of serotonin [ 29 ]. To enter the brain, a carrier protein must transport tryptophan through the blood-brain barrier.
However, tryptophan is in constant competition with six other amino acids isoleucine, leucine, phenylalanine, tyrosine, and valine to bind to the carrier [ 30 ]. Consuming rich protein sources provides the body with the mentioned amino acids in abundance, making it more arduous for tryptophan to pass through the barrier.
As a result, serotonin production might be reduced. Moreover, in a clinical trial study on 18 individuals who were divided into two groups, it was revealed that the group who consumed plant-based meals during the test had higher brain tryptophan and tyrosine levels than those who consumed meals high in animal sources [ 31 ].
Another explanation may involve the metabolism of homocysteine. Homocysteine is a byproduct of animal protein as it is converted from methionine, an amino acid found abundantly in red meat. Higher homocysteine levels are strongly associated with major psychiatric disorders [ 33 ].
It is suggested that elevated homocysteine levels could cause cerebral vascular disease and neurotransmitter deficiency [ 34 ]. It should be noted that several other factors could also promote diet-induced damage to mental health, including oxidative stress, insulin resistance, and inflammation [ 35 ].
They could be the inevitable outcomes of a long-term high intake of animal products that contain nutrients such as saturated fatty acid, arachidonic acid, heme iron, and cholesterol, which are known to cause inflammation [ 36 ].
Furthermore, excessive consumption of red meat was shown to alter gut microbiota composition [ 38 ], generating bioactive metabolites that could cause neuroinflammation through the gut-brain-axis [ 39 ].
Our findings were in general agreement with previous studies investigating the matter. A meta-analysis of 8 observational studies showed that meat consumption could be associated with a slightly higher risk of depression [ 40 ].
In a cross-sectional study conducted on Asian residents of the United States, a vegetarian diet which was characterized by no intake of meat, poultry, and fish was found to be inversely associated with the prevalence of depression [ 41 ]. furthermore, a cohort study conducted on participants found that the Mediterranean diet, which is rich in plant-based foods and low in red meat, had an inverse relation with depression [ 42 ].
The same conclusion was drawn in another large cohort study where the relationship between the dietary approach to hypertension DASH diet and depression was assessed [ 43 ]. A Japanese study found that plant protein was associated with decreased prevalence of depressive symptoms [ 44 ].
A clinical study by Beezhold et al. concluded that restricting animal-based foods such as meat, fish, and poultry improved short-term mood [ 45 ]. On the other hand, Li et al. reported that protein intake from milk and milk products was inversely associated with depressive symptoms [ 46 ].
They suggested that a-lactalbumin, a whey-derived protein that is a rich source of tryptophan, could exert beneficial effects on mood and cognition. The present study could further expand our knowledge regarding the association of the protein with mental well-being.
Still, some limitations should be noted. First, the recall bias in reporting dietary intake has probably affected the results. The cross-sectional nature of our study was another limitation, as it prevented us from inferring causality.
The study was performed only on females aged 20—50 years, which affects the generalizability to the larger population. Also, due to the different influence of gonadal steroids on mood [ 47 ], we could have gotten better insight into the variable of sex if men had also been present.
Furthermore, it has been reported that the menstrual cycle could affect depressive symptoms, which were not regarded in our study [ 48 ]. Also, the DASS is a self-reported scale based on a dimensional rather than a categorical conception of mental disorder.
This scale is used to measure the severity of symptoms of anxiety, stress, and depression and is helpful for screening, not for diagnosis. In conclusion, we found that high adherence to animal protein is associated with an elevated risk of psychiatric disorders.
Future longitudinal studies are required to further our understanding of the effect of different protein sources on mental health.

Nutr J. Li Y, Zhang C, Li S, Zhang D. On the other hand, non-essential amino acids can be synthesized by the body, even if we do not get them from dietary sources. However, this does not diminish their importance, as they are still vital for supporting various bodily functions.
Non-essential amino acids include alanine, asparagine, aspartic acid, glutamic acid, and tyrosine. Some amino acids are termed conditionally essential. This means that they are non-essential except in times of illness, stress, and periods of growth.
Conditionally essential amino acids include arginine, cysteine, glutamine, tyrosine, glycine, proline, and serine. Neurotransmitters are chemical messengers that transmit signals between neurons in the central nervous system to facilitate communication between nerve cells.
Neurotransmitters are involved in a wide range of physiological processes, including motor control, sensory perception, cognitive function, and mood regulation.
Imbalances or dysregulation in neurotransmitter levels can contribute to the development of various psychiatric and mental health conditions. Amino acids serve as essential building blocks in neurotransmitter synthesis. In particular, the aromatic amino acids — tryptophan, tyrosine, and phenylalanine — serve as precursors for the neurotransmitters serotonin, dopamine, and noradrenaline, which are key players in mood regulation.
Glutamate, another dietary amino acid, acts as neurotransmitter along with being a precursor for gamma-aminobutyric acid GABA. Both glutamate and GABA are involved in mood regulation, but the direct link between dietary intake and their impact on brain functions is not fully understood.
Serotonin, also called 5-hydroxytryptamine 5-HT , is synthesized by the hydroxylation of tryptophan to 5-hydroxy-L-tryptophan 5-HTP , followed by the decarboxylation to 5-HT. Enzymatic cofactors required for these reactions include iron, folic acid, vitamin B6, and magnesium.
Reduced serotonin levels are linked to anxiety, depression, other mental health disorders, sleep problems, and digestive issues 13 , Catecholamines, encompassing dopamine, norepinephrine, and epinephrine, are molecules that act as both neurotransmitters and hormones.
The synthesis pathway of catecholamines begins with the conversion of phenylalanine to tyrosine. Tyrosine serves as the precursor for synthesizing dopamine and norepinephrine, where it first undergoes a series of conversions to form dopamine.
Once dopamine is created, it can undergo additional enzymatic modifications to give rise to norepinephrine. Essential cofactors for the reactions involved in this synthesis pathway include iron, folic acid, vitamin B6, vitamin C, and copper.
Dopamine depletion is associated with feelings of fatigue, apathy, low mood, poor concentration, and the tendency to withdraw from social interactions Low levels of norepinephrine can cause lethargy, lack of concentration, ADHD, and depression 3.
The most common nutritional deficiencies observed in patients with mental health disorders are amino acids, omega-3 fatty acids, and B vitamins.
Results of clinical studies support the notion that amino acid supplementation is often helpful in treating mood disorders, including anxiety and depression. A small, randomized crossover study concluded that college students eating a diet high in L-tryptophan experience improved mood, as noted by fewer symptoms of anxiety, irritability, and depression, compared to those eating a diet low in L-tryptophan.
A systematic review that included 11 studies investigating the effects of supplemental tryptophan on mood concluded taking 0. DLPA is a combination of D- and L- forms of phenylalanine. DLPA has been studied as an adjunctive therapy for depression with positive clinical outcomes. Small clinical trials have found that mg of DLPA daily effectively reduces feelings of agitation, sluggishness, and depressed mood in as quickly as days 5 , Other trials have compared DLPA to pharmacologic antidepressant therapy, revealing its ability to enhance positive clinical outcomes when used in conjunction with drug monotherapy.
Furthermore, DLPA shows a comparative advantage by having fewer associated side effects than prescription medications. A study investigated the impact of a dietary supplement formulated with tyrosine, tryptophan, and blueberry extract during the early postpartum period. The researchers found that women who took the supplement over postpartum days had dramatically reduced rates of postpartum depression compared to those who did not receive the supplement.
Maintaining optimal amino acid status through a nutritious diet is fundamental for supporting overall health, cognitive function, and preventing various health conditions associated with amino acid deficiencies. Dietary sources of the amino acids emphasized in this article are listed below:.
Functional medicine takes a personalized and comprehensive approach to addressing amino acid imbalances, recognizing the intricate connections between nutrition, biochemistry, and overall health. In addressing amino acid balance, functional medicine emphasizes personalized dietary strategies tailored to an individual's unique biochemical needs.
This approach involves assessing specific amino acid profiles through advanced testing discussed below and then devising personalized diets that optimize the intake of deficient or imbalanced amino acids. Additionally, supplementation with targeted amino acids may be recommended to address specific deficiencies identified through these diagnostic assessments.
Lifestyle changes, including stress management, are also incorporated into holistic protocols to support overall amino acid balance, as evidence shows that acute and chronic stress affect amino acid levels.
The Organic Acids Test OAT by Mosaic Diagnostics is a comprehensive diagnostic tool that indirectly assesses amino acid levels by analyzing urine organic acid metabolites. This test provides valuable insights into the metabolic pathways and can reveal imbalances in amino acid metabolism.
If the OAT reveals imbalances in amino acid or neurotransmitter metabolism, healthcare providers can design a treatment plan to address these deficiencies. This may involve recommending specific dietary changes or supplements to restore optimal levels.
A micronutrient panel, such as the Cellular Micronutrient Assay by Cell Science Systems , is a diagnostic tool that directly evaluates the levels of various essential vitamins, minerals, and amino acids in the body, offering a comprehensive overview of an individual's nutritional status.
In the context of amino acids and mood regulation, a micronutrient panel can provide valuable insights into potential deficiencies or imbalances that may contribute to mood disorders. Similarly to the OAT, the results from a micronutrient panel can guide treatment plans by identifying nutritional areas of concern and helping healthcare professionals design targeted interventions.
A holistic approach to mood regulation recognizes that various factors, including genetic, psychological, and social elements, influence mental health. A functional medicine approach to mental health focuses on finding the root cause of symptoms and designing an integrative treatment plan incorporating nutrition, botanical medicine, exercise, sleep hygiene, and mind-body modalities alongside traditional treatment interventions.
This comprehensive strategy aims to alleviate symptoms and promote long-term mental well-being by addressing the root causes of imbalances. Other dietary supplements can be used alongside amino acid therapy to support endogenous biosynthesis pathways of neurotransmitters holistically and support mental health and cognitive function.
As mentioned above, iron, magnesium, copper, and B vitamins 6, 9, and 12 are essential cofactors for the enzymes involved in neurotransmitter synthesis. Bright light exposure, specifically through light therapy or phototherapy, has shown promising results in the treatment of depression, particularly seasonal affective disorder SAD.
Light therapy involves exposure to a bright light, typically mimicking natural sunlight, and is designed to regulate circadian rhythms and improve mood. An overwhelming body of evidence points to the positive relationship between exercise and mood.
Exercise reduces symptoms by promoting the release of endorphins, which act as natural mood lifters, and improving blood flow and oxygenation to the brain.
Physical activity also helps to regulate the stress hormone cortisol, contributing to a more balanced stress response.
While amino acid supplementation can offer various health benefits, it is crucial to be aware of potential risks and side effects associated with their use.
Overconsumption of certain amino acids, especially through supplementation, can lead to imbalances in the overall amino acid profile, potentially causing adverse effects. For instance, excessive intake of branched-chain amino acids BCAAs may cause digestive upset or affect blood sugar levels.
Phenylketonuria PKU is a rare genetic disorder characterized by the body's inability to process phenylalanine due to a deficiency in the enzyme required to break it down.
Without this enzyme, phenylalanine levels can become elevated in the blood and lead to the accumulation of harmful byproducts, which can negatively affect the brain. Patients with PKU require a low-phenylalanine diet, and phenylalanine supplementation would be contraindicated in this population.
Arginine is an amino acid that promotes the proliferation of some viruses. Following a low-arginine diet and avoiding arginine-containing supplements during viral illnesses and outbreaks is often recommended. Professional guidance is essential to ensure the safe and effective use of amino acid supplements.
Healthcare providers, including registered dietitians or nutritionists, can assess individual needs, considering factors like age, health conditions, and medications, to provide personalized dosing recommendations to ensure the safe use of amino acid supplements.
Amino acids are an important nutritional factor in mood regulation, serving as building blocks for neurotransmitters that influence emotional health. A functional medicine approach recognizes the interconnectedness of nutrition, biochemistry, and mood. By embracing amino acids as integral components of mental health, individuals can consider tailored interventions, including dietary modifications and supplementation, to optimize neurotransmitter synthesis and support overall emotional balance.
