NOW L-Methionine
An essential amino acid for proper cellular function and protein synthesis, with Vitamin B-6 to help metabolize proteins, fats and carbohydrates. The importance of sulfur-containing amino acids for growth and protein synthesis has been recognized since 1915. Despite the availability of food proteins in the typical western diet, some individuals are likely to have inadequate intakes, because of either inadequate intake of total protein or selection of a restricted variety of proteins that provide inadequate sulfur amino acids.
L-methionine is classified as an essential amino acid for humans and therefore must be supplied in the diet, principally derived from dietary proteins. Rich sources of L-methionine include cheeses, eggs, fish, meat and poultry.L-methionine is also found in fruits and vegetables, but not as abundantly. Small amounts of free L-methionine occur in vegetables, vegetable juices and fermented foods. In addition to its role as a precursor in protein synthesis, L-methionine participates in a wide range of biochemical reactions, including the production of S-adenosylmethionine (SAM or SAMe), L-cysteine, glutathione, taurine and sulfate. Vitamin B-6 or pyridoxine is added to this formulation as it is an essential cofactor in the metabolism of amino acids. It is also involved in carbohydrate and lipid metabolism. In the body, pyridoxine is converted to coenzymes pyridoxal phosphate and pyridoxamine phosphate, in a wide variety of metabolic reactions. These reactions include transamination of amino acids, conversion of tryptophan to niacin, synthesis of gamma-aminobutyric acid (GABA), metabolism of serotonin, norepinephrine, dopamine, polyunsaturated fatty acids and phospholipids, and the synthesis of the heme component of hemoglobin.
