Isotonix L-Tryptophan is an isotonic capable form of the essential amino acid, l-tryptophan. L-Tryptophan is an essential amino acid that helps maintain healthy levels of serotonin in the brain which helps regulate mood. Isotonix L-Tryptophan provides maximum results by including niacin and Vitamin B6, members of the B vitamin family, which promote the normal absorption of L-tryptophan.

Key Ingredients of Isotonix® L-Tryptophan:  L-Tryptophan 500 mg An essential amino acid that promotes the normal synthesis and structure of proteins. In the body, L-tryptophan is converted into niacin (vitamin B3) and serotonin, a neurotransmitter which promotes the body’s ability to regulate anger, aggression, mood, and sleep. By supplementing with Isotonix L-Tryptophan, serotonin production can be supported, which will promote sleep and enhance mood.* The metabolism of L-tryptophan to serotonin is supported in large part by the following vitamins:   Vitamin C 75 mg A water-soluble vitamin which acts as an antioxidant, supports normal growth and repair of body tissues, supports cardiovascular health, protects against free radicals, and supports cognitive health and performance. Vitamin C supports the hydroxylation of L-tryptophan to serotonin.*  Niacin (Vitamin B3) 20 mg Plays an essential role as a coenzyme (NAPH/ NADPH) for about 200 enzymes which promote normal tissue respiration, synthesis of fatty acids and steroid hormones, the metabolism of carbohydrates and amino acids, and the transport of hydrogen. When niacin levels are low, the body can use L-tryptophan to manufacture the vitamin. To produce 1 mg of niacin, the body must use 60 mg of L-tryptophan, a process which can rapidly deplete L-tryptophan levels. When niacin levels are sufficient, L-tryptophan can be used for other needs such as retaining healthy levels of serotonin.* Pyridoxine HCl (Vitamin B6) 4 mg Promotes the normal conduction of nerve impulses, regulation of steroid hormones, catabolism of glycogen for glucose, heme synthesis, and the synthesis/metabolism of amino acids and neurotransmitters. After conversion to pyridoxal phosphate (PLP), vitamin B6 acts as a cofactor for many enzymatic reactions involving L-tryptophan, including L-tryptophan’s conversion to serotonin.*
