Amino Acids

One of the most researched and effective supplements for physical performance, muscle growth, and emerging cognitive benefits.

Collagen is the most abundant structural protein in the body, forming the framework of skin, bones, tendons, and cartilage. Hydrolyzed collagen peptides are widely supplemented for joint health, skin elasticity, and connective tissue support.

L-Theanine is an amino acid found primarily in tea leaves that promotes relaxation without sedation by increasing alpha brain wave activity. It is widely used for stress relief, focus enhancement (especially paired with caffeine), and sleep quality improvement.

NAC is a stable, bioavailable form of the amino acid cysteine and the most efficient precursor to glutathione, the body's primary intracellular antioxidant. It is widely studied for respiratory, liver, and mental health support.

Glucosamine is an amino sugar naturally present in cartilage and synovial fluid. It is one of the most widely used supplements for osteoarthritis, supporting cartilage structure and reducing joint pain and stiffness.

Chondroitin sulfate is a major glycosaminoglycan found in cartilage that helps retain water, maintain elasticity, and inhibit degradative enzymes. It is widely used for osteoarthritis symptom relief and cartilage protection.

BCAAs are three essential amino acids — leucine, isoleucine, and valine — that play a central role in muscle protein synthesis, exercise recovery, and energy production during prolonged activity.

SAMe is a naturally occurring methyl donor synthesized from methionine and ATP. It is involved in over 100 methylation reactions and is clinically studied for mood support, joint health, and liver function.

Beta-alanine is a non-essential amino acid that serves as the rate-limiting precursor for carnosine synthesis in skeletal muscle. It is primarily used to buffer intramuscular acid during high-intensity exercise, delaying fatigue.

Glycine is the simplest amino acid and serves as a key building block for collagen, glutathione, and creatine. It plays an important role in sleep quality, neuroprotection, and connective tissue health.

L-Arginine is a semi-essential amino acid that serves as a precursor to nitric oxide, a molecule critical for vasodilation and blood flow. It supports cardiovascular health, exercise performance, and immune function.

L-Glutamine is the most abundant amino acid in the body, playing essential roles in gut integrity, immune function, and muscle recovery. Demand increases significantly during periods of physical stress, illness, or intense exercise.

5-HTP is the direct precursor to serotonin, derived from the seeds of the African plant Griffonia simplicifolia. It is used to support mood, reduce anxiety, improve sleep quality, and curb appetite.

Citrulline is a non-essential amino acid that serves as the most effective oral precursor to L-arginine and nitric oxide. It supports cardiovascular function, exercise performance, and blood flow.

HMB (beta-hydroxy beta-methylbutyrate) is a metabolite of the essential amino acid leucine. It helps reduce muscle protein breakdown, supporting lean mass preservation during caloric deficit and accelerating recovery from resistance training.

L-Tryptophan is an essential amino acid and the precursor to serotonin and melatonin. It supports mood regulation, sleep onset, and emotional well-being through the serotonin pathway.

L-Carnitine is an amino acid derivative essential for transporting long-chain fatty acids into mitochondria for energy production. It supports fat metabolism, exercise recovery, and cognitive function in its acetylated form (ALCAR).

L-Tyrosine is a non-essential amino acid and precursor to dopamine, norepinephrine, and epinephrine. It is primarily used to support cognitive performance under stress, improve focus, and maintain mental resilience during demanding tasks.

Taurine is a conditionally essential sulfur-containing amino acid abundant in the heart, brain, and retina. It supports cardiovascular function, acts as a cellular antioxidant, and plays important roles in bile acid conjugation and osmoregulation.

Glutathione is the body's most abundant endogenous antioxidant, a tripeptide composed of glutamate, cysteine, and glycine. It plays a critical role in neutralizing free radicals, detoxifying xenobiotics, and supporting immune function.

Lysine is an essential amino acid critical for collagen synthesis, calcium absorption, and immune function. It is widely used to prevent and reduce the frequency of herpes simplex outbreaks.

Methionine is an essential sulfur-containing amino acid that initiates protein synthesis and serves as the precursor to SAMe, cysteine, and taurine. It plays key roles in methylation, detoxification, and antioxidant defense.

GABA (gamma-aminobutyric acid) is the primary inhibitory neurotransmitter in the central nervous system. Supplementation is used to promote relaxation, reduce stress-related anxiety, and improve sleep quality.

D-Aspartic acid (DAA) is an amino acid enantiomer that plays a role in neuroendocrine signaling. It is primarily researched for its potential to transiently increase testosterone and luteinizing hormone levels in men.

Ornithine is a non-proteinogenic amino acid involved in the urea cycle, helping the body eliminate ammonia. It is commonly supplemented to reduce exercise-induced fatigue and support growth hormone release during sleep.
