Now that it is \u003c\/font\u003e\u003cfont size=\"4\" face=\"Verdana\"\u003eclassified as a Natural Health Product, numerous consumers are expected to capitalize \u003c\/font\u003e\u003cfont size=\"4\" face=\"Verdana\"\u003eon the potential health benefits of oral tryptophan supplementation.\u003c\/font\u003e\u003cb\u003e \u003c\/b\u003e\u003c\/p\u003e\r\n  \u003cp\u003e\u003cfont size=\"4\" face=\"Verdana\"\u003eL-Tryptophan is a large neutral amino acid essential to \u003c\/font\u003e\u003cfont size=\"4\" face=\"Verdana\"\u003ehuman metabolism because it is the metabolic precursor of serotonin (a \u003c\/font\u003e\u003cfont size=\"4\" face=\"Verdana\"\u003eneurotransmitter), melatonin (a neurohormone), and niacin (vitamin B3) which assist \u003c\/font\u003e\u003cfont size=\"4\" face=\"Verdana\"\u003ein the regulation of sleep, positive mood and immune function. L-Tryptophan is not \u003c\/font\u003e\u003cfont size=\"4\" face=\"Verdana\"\u003esynthesized by the body and must be obtained from the diet. As a component of dietary \u003c\/font\u003e\u003cfont size=\"4\" face=\"Verdana\"\u003eprotein, tryptophan is particularly plentiful in chocolate, oats, bananas, dried dates, \u003c\/font\u003e\u003cfont size=\"4\" face=\"Verdana\"\u003emilk, cottage cheese, meat, fish, turkey, and peanuts. It requires active transport and  \u003c\/font\u003e\u003cfont size=\"4\" face=\"Verdana\"\u003ecompetes for the same receptors with other neutral amino acids – tyrosine, \u003c\/font\u003e\u003cfont size=\"4\" face=\"Verdana\"\u003ephenylalanine, valine, leucine, and isoleucine, so a food that is high in tryptophan may \u003c\/font\u003e\u003cfont size=\"4\" face=\"Verdana\"\u003enot necessarily increase brain tryptophan and serotonin levels if it also contains a large \u003c\/font\u003e\u003cfont size=\"4\" face=\"Verdana\"\u003equantity of these other amino acids. Tryptophan hydroxylase is the rate-limiting \u003c\/font\u003e\u003cfont size=\"4\" face=\"Verdana\"\u003eenzyme for serotonin production and involves the conversion of tryptophan to \u003c\/font\u003e\u003cfont size=\"4\" face=\"Verdana\"\u003e5-hydroxytryptophan (5-HTP), which is then converted to serotonin. This enzyme can \u003c\/font\u003e\u003cfont size=\"4\" face=\"Verdana\"\u003ebe inhibited by stress, insulin resistance, magnesium or vitamin B6 deficiency, or \u003c\/font\u003e\u003cfont size=\"4\" face=\"Verdana\"\u003eincreasing age, so additional supplies of tryptophan may be required in certain \u003c\/font\u003e\u003cfont size=\"4\" face=\"Verdana\"\u003ecircumstances.
