Best Vegetarian Amino Acid Supplements in 2026

MANY PEOPLE NEED A B6 SUPPLEMENT - Your body doesn’t produce vitamin B6, so you have to get it from foods like eggs, brewer’s yeast, carrots, chicken, fish, brown rice, whole grains and cabbage. If you don’t eat enough of these foods, you should choose a high-quality supplement—because B6 is really, really good for you.

CARDIOVASCULAR HEALTH – There’s an amino acid called homocysteine that’s a well-known marker for both heart and brain health. Maintaining homocysteine levels already within normal range is good for your cardiovascular system and your circulatory health. Vitamin B6 helps maintain already-healthy homocysteine levels...which keeps your blood flowing freely!

IMMUNE HEALTH, MOOD & MORE – Vitamin B6 helps encourage a healthy immune response, so you’re ready for what the world throws at you. And because your body uses vitamin B6 to make the neurotransmitter serotonin, this essential vitamin helps support a better mood. And because of its aforementioned effect on homocysteine, vitamin B6 promotes brain health, too.

WHAT IS GLUTATHIONE? – Glutathione is a naturally occurring antioxidant in your body that helps your liver do its job. This formula combines glutathione with several other antioxidants and antioxidant precursors—to help take some of the load off of your hard-working liver.

DEFEND YOUR LIVER AGAINST CELLULAR STRESS – The natural biological processes within your body create free radicals, compounds that can exert oxidative stress on liver cells and elsewhere. Our formula helps quench free radicals with glutathione and vitamin C.

EXTRA LIVER SUPPORT – We’ve also included L-cysteinein this formula. This amino acid helps your body produce its own glutathione. Plus, it gives your liver direct support with some of its detoxification duties. Including it in this formula was a no-brainer!

FUEL YOUR ACTIVE LIFESTYLE – Glutamine is an amino acid your body uses for protein production. While it’s a must-have among serious athletes, glutamine is a great option for anyone who leads an active lifestyle.

GUT HEALTHY, IMMUNE STRONG – Glutamine can be found in the blood, as well as stored in the skeletal muscles and liver, and in higher concentrations than any other amino acid. It’s an important energy source for cells lining the gut and immune cells, making it critical for a healthy digestive tract and immune response.

ANTIOXIDANT SUPPORT - Regular body movement is terrific for whole-body health. But engaging in heavy exercise can affect glutamine levels, causing stress to the body. Our L-Glutamine formula helps support antioxidant defenses to maintain muscle health.

AMINO ALL STAR – L-Arginine does so much for your body—benefitting everything from your heart to your immune health. But while your body produces this semi-essential amino acid naturally, and you can get it from certain foods, it can be hard to make enough. That’s why a high-quality supplement is so important.

SUPPORT ALREADY-HEALTHY BLOOD PRESSURE & MORE – Your body uses L-Arginine for many different purposes—including maintaining already-healthy blood pressure. Another key use is tocreate nitric oxide, a chemical that helps expand your blood vessels. Arginine also supports healthy arterial elasticity.

IMMUNE HEALTH & BIOMARKERS – L-Arginine can help maintain a healthy immune response. It’s also been associated with already-healthy levels of C reactive protein, a biomarker that is used to measure cardiovascular health, especially as you age.

FIGHT OXIDATIVE STRESS & BOOSTS ENERGY – Acetyl-L-carnitine helps fight oxidative stress at the cellular level. Combine that with this nutrient’s ability to facilitate cellular energy production, and you have an invaluable daily supplement for whole-body wellness.

GOOD FOR YOUR BRAIN - Acetyl-L-carnitine is great for supporting the parts of your body that need lots of cellular energy, such as your brain and nervous system (as well as your heart and cardiovascular system). So much so that this specialized carnitine supplement can even help with things not usually associated with your mind, such as nerve comfort and mood health.

A BETTER KIND OF CARNITINE – Carnitine helps turn food into cellular energy. This supplement contains Acetyl-L-Carnitine Arginate, an advanced form of carnitine that promotes even better youthful cellular energy metabolism than traditional carnitine. This in turn means even greater benefits for brain health, nerve health and cellular energy production.

THE LITTLE AMINO THAT COULD – Lysine is one of the building blocks of protein. It’s also an essential amino acid, which means your body cannot make lysine on its own. And not everybody gets enough: athletes as well as those following plant-based diets may need to supplement with lysine.

AGING THE HEALTHY WAY – Lysine helps inhibit glycation, a biochemical reaction where lipids and proteins bind to sugars in non-functional ways. Glycation is one of several factors that lead to the physiological effects of aging. So getting enough lysine can help you age gracefully!

HEALTHY RESPONSE TO STRESS – Want to know something else about lysine? This helpful little amino acid helps encourage your body’s healthy response to stress. It also helps you maintain lean body mass, as well as your body’s healthy store of nitrogen. That’s lysine for the win!

ESSENTIAL NUTRIENT FOR A HEALTHY BRAIN - Phenylalanine is a vital amino acid that is crucial to cognitive performance and overall well-being. The liver converts it to L-tyrosine, which your nervous system then uses to make important neurotransmitters and hormones, including dopamine, norepinephrine and adrenaline (epinephrine).

MOOD & BRAIN HEALTH - Studies show that supplementing with phenylalanine encourages healthy neurotransmitter production and brings a wide range of cognitive health benefits. That’s because the body uses phenylalanine to make neurotransmitters that regulate mood, memory and focus, promoting a healthy mood and overall cognitive performance.

NOURISHING PROTECTION FOR YOUR BRAIN CELLS - Research shows that phenylalanine supplementation also helps protect your delicate brain cells (neurons). That’s because your body uses it to produce norepinephrine, which in addition to acting like a chemical messenger, this neurotransmitter also promotes a healthy inflammatory response, protects neurons from oxidative stress caused by free radicals, and encourages healthy brain cell growth and connectivity.

BE VITAMIN B-5 ALIVE — Pantothenic acid, or vitamin B-5, is not nearly as famous as its cousins vitamin B3 niacin or B12 methylcobalamin. But B5 is vitally important in its own right. This member of the vitamin B family is essential to several aspects of healthy metabolism—mainly the healthy metabolism of lipids, amino acids and glucose...as well as supporting cellular energy production.

BUILDS COENZYME A – You’re probably wondering how B5 helps with so many different things. The answer is that your body uses pantothenic acid to build a compound called coenzyme A. This coenzyme is super important: along with its value for metabolic health, coenzyme A facilitates hemoglobin, neurotransmitter, hormone, protein and lipid synthesis.

EASY ON YOUR STOMACH – Some pantothenic acid supplements can be hard on the stomach. That’s why we’ve combined our pantothenic acid formula with calcium. This makes it easier on your stomach, and it also makes it more shelf-stable.

SLEEP SOUNDLY – Melatonin promotes healthy sleep/wake patterns, and supports morning alertness and overall quality of life. This hormone, derived from the amino acid tryptophan, is created in the pineal gland and releases it mostly at night. But not everybody produces enough melatonin naturally—that’s where this high-quality melatonin supplement can help!

SUPPORTS WHOLE BODY HEALTH – Melatonin helps support circadian rhythms and immune function, promote cellular and DNA health, as well as helps inhibit oxidative stress and protects mitochondria.

ALL NIGHT SUPPORT – Melatonin increases the speed of falling asleep. Our formula delivers 1mg of melatonin to encourage the onset, duration and quality of sleep.

HEALTHY STRESS RESPONSE - L-Theanine is an amino acid found in tea that produces a calming effect by favorably modulating several aspects of brain activity. Our L-Theanine formula promotes a calm and relaxed state of mind.

Product Note: Exposure to heat or sunlight may lead to melting/damage of product. Hence customers are expected to be available during the product delivery

CALMING EFFECTS AT THE CELLULAR LEVEL - L-Theanine has been shown to modulate the formation of the neurotransmitter GABA (gamma amino butyric acid). This brain chemical messenger regulates levels of dopamine and serotonin, two neurotransmitters that also support relaxation.

SUPPORTS MUSCLE RECOVERY & ENDURANCE - BCAAs are used by athletes for a reason: Research shows that BCAAs help to both maintain and build muscle strength and endurance, while supporting physical performance and brain function. But BCAA supplementation can be advantageous for anyone—not just strength or endurance athletes.

BCAAS FOR IMMUNE SUPPORT - Athletes need healthy immune function for peak performance, and BCAAs help maintain healthy immune system function.This is another reason why BCAAs can be beneficial to anyone seeking to bolster their natural defenses.

NOT JUST FOR ATHLETES – You don’t have to be a professional athlete or even a weekend warrior to benefit from BCAAs. Take a page from the athlete’s playbook and help maintain healthy skeletal muscle, promote brain function and support your immune system with Branched Chain Amino Acids.

WHAT IS ARGININE ORNITHINE POWDER? Exercising regularly promotes whole body health and longevity. But muscle soreness can make it difficult to maintain an exercise routine. That’s where Arginine Ornithine Powder comes in. These amino acids have both been shown to support muscle mass, health and recovery after exercise—and have other potent whole-body health benefits as well.

MANY FUNCTIONS, ONE AMINO ACID : Arginine plays many different roles in keeping you healthy. As a semi-essential amino acid, arginine is involved in immune and endothelial function. It helps your body produce nitric oxide, which supports vascular relaxation and healthy circulation.

WHY DID WE ADD L-ORNITHINE? This is a non-essential amino acid that the body actually makes out of arginine. Our cells use ornithine to produce proline, which is needed for collagen formation, as well as nitrogen-based compounds called polyamines that help support gene expression, division and survival. Both arginine and ornithine help your cells convert ammonia, an unwanted byproduct of protein metabolism, into urea, a compound that can be safely excreted via the kidneys.

WIDE RANGE OF BENEFITS - Best known for supporting heart health, taurine actually has a wide range of health benefits, from encouraging healthy nervous system function to maintaining already-healthy blood pressure and blood glucose levels. Athletes love it, too, since this nutrient helps support muscle recovery after exercise.

NATURALLY OCCURING AMINO ACID - Found in most of the cells and tissues in the human body, taurine helps regulate water and calcium movement across cell membranes. This free amino acid also encourages the production of bile salt in the liver.

A HEALTHY AGING MUST-HAVE - Taurine has been show to help maintain muscle mass and function as we age--so we can stay limber long into our golden years. Our Taurine Powder is unflavored so that it can easily be mixed into your favorite drink, smoothie or snack for an extra boost while on the go.

Youthful energy levels – It's a fact: as we age, our cellular energy levels decline—mainly because our mitochondria, the powerhouse of our cells, aren't functioning the way they did when we were younger. L-Carnitine is an amino acid produced in your body that plays an important role in supporting the optimal functioning of your mitochondria—so you can reclaim that youthful energy.

Keep that metabolism going – As we age, levels of carnitine decline in all of our tissues, which affects metabolic activity in addition to our cellular energy. Boosting carnitine levels with L-Carnitine can help you maintain youthful metabolic activity.

Anti-aging must-have – In addition to supporting cellular energy and metabolic activity, L-Carnitine also helps you support already-healthy blood pressure, maintain a healthy body fat composition and promote your brain cell defenses against age-related memory and cognitive decline. It’s the perfect way to show that age really is just a number!
