Amino acids

Acetyl L-Carnitine is truely a mind-body nutrient. Acetyl-L-carnitine occurs naturally in the body and is also found in animal products, primarily red meat. Acetyl-L-carnitine helps the body burn fat for energy. Acetyl-L-carnitine also improves the body’s production of an important neurotransmitter, acetylcholine, and may reduce oxidative damage in the brain. Several studies have shown that there may be some positive effects of acetyl-L-carnitine supplementation in Alzheimer's patients. Other research suggests that acetyl-L-carnitine may help slow age-related mental decline, protect the brain after a stroke, and improve blood flow to the brain. Acetyl-L-carnitine might also be effective in the treatment of diabetic and chemotherapy-induced neuropathy and in the regeneration of nerves in the arms and legs.

The essential amino acid l-tryptophan helps support relaxation, restful sleep, and positive mood. It plays a part in the synthesis of both melatonin and serotonin, hormones involved with mood and stress response and sleep/wake cycles. l-Tryptophan also supports immune functions because it is the body’s precursor to the kynurenines that regulate immunity. If needed, l-tryptophan converts to niacin in the body, which supports circulation, a healthy nervous system, the metabolism of food, and the production of hydrochloric acid for the digestive system. Source Naturals l-Tryptophan is extremely pure and is regularly tested to ensure the highest standards of quality

L-Tyrosine is a free-form amino acid which rapidly crosses the blood-brain barrier. It is a precursor for the neurotransmitters dopamine, norepinephrine and epinephrine, for thyroid hormones, and for enkephalins, special peptides which subdue messages of physical discomfort. L-Tyrosine is also a precursor for the protective skin pigment melanin.

L-Valine is an an essential amino acid, specifically classified as a "branched-chain amino acid" (BCAA). BCAA's stimulate protein synthesis directly in muscle tissue. Valine is a major fuel involved in anabolic (tissue-building) reactions, and stimulates muscle protein synthesis.

N-Acetyl cysteine is a stable form of the sulfur amino acid L-cysteine, and is a powerful antioxidant. It is also a precursor of glutathione, a major antioxidant. Glutathione is also the precursor, along with selenium, of glutathione peroxidasse, one of the most important antioxidant enzymes in the body. N-Acetyl cysteine is better than glutathione supplements, which may break down during digestion and lose potency.

N-Acetyl L-Tyrosine is a more rapidly absorbed and bioavailable form of the amino acid L-tyrosine, and is less prone to urinary excretion. L-Tyrosine is converted in the body to key biologic compounds, including epinephrine, dopamine, L-dopa, Co-Q10, thyroid hormones, and melanin. The B vitamins pyridoxine (B-6), and folic acid are provided to assist in the conversion process

Taurine is a crystalline, free-form amino acid. It is a soothing, inhibitory neurotransmitter and plays a major role in stabilizing the heartbeat and electrical activity of the nerves.
Taurine is also necessary for the proper functioning of the "sodium/potassium ATP-ase pump", which regulates the ion balance between the cells and the extracellular fluid which surrounds them. This critically important "pump" actually uses 7% to 40% of the ATP energy our bodies produce.
