\r\n Tryptophan is one of the seven essential amino acids, i. e. it must be \r\n provided by the diet because our body cannot synthesise it. It is a \r\n so-called aromatic amino acid (like phenylalanine and tyrosine) that is \r\n both rare (1% of the amino acids present in proteins) and very fragile.\r\n <\/p>\r\n

\r\n Precursor of serotonin, melatonin and niacin (Vitamin B3), tryptophan is \r\n a calming, anti-depressant and sleep inducer.\r\n <\/p>\r\n

\r\n Discovered in 1901, it has been used for many years to combat \r\n depression, promote weight loss and sleep.\r\n <\/p>\r\n

\r\n With regard to weight loss, it is known that stress can lead some people \r\n to consume large quantities of carbohydrates which cause a momentary \r\n feeling of well-being but which unfortunately increase calorie intake \r\n and promote fat storage. Taking Tryptophan or 5-HTP \r\n (5-Hydroxytryptophan) helps to improve the psychological state while \r\n avoiding excess weight.\r\n <\/p>\r\n

\r\n Tryptophan stimulates the release of growth hormone and participates in \r\n the formation of lymphocytes which are essential for the immune system.\r\n <\/p>\r\n

\r\n BCAAs and other aromatic amino acids (Tyrosine and Phenylalanine) \r\n compete with Tryptophan at the entrance to the brain.\r\n <\/p>\r\n

\r\n SEROTONIN\r\n <\/h2>\r\n

\r\n An amine present in most tissues of the body, it acts as a chemical \r\n mediator. It plays a fundamental role in many functions, particularly in \r\n the control of appetite and mood as well as in depression and anxiety.\r\n <\/p>\r\n

\r\n In the brain, Tryptophan is transformed after hydroxylation into 5-HTP \r\n (5-Hydroxytryptophan) to give serotonin.\r\n <\/p>\r\n

\r\n TRYPTOPHAN: THE RETURN\r\n <\/h2>\r\n

\r\n In the United States, in 1989 Tryptophan had been implicated in an \r\n epidemic of a new disease: eosinophilia-myalgia syndrome. This disease \r\n resulted in the death of 37 people and crippled over a thousand. <\/em>\r\n <\/p>\r\n

\r\n The Japanese company Showa Denko, responsible for the marketing of \r\n this food supplement produced by the genetic manipulation of a \r\n bacterium, and following a bad filtration allowing a contaminant to \r\n pass, is indeed the real cause of what has led for about fifteen<\/em>\r\n <\/p>\r\n

\r\n years the banning of Tryptophan as a dietary supplement. . . However, \r\n one cannot ignore the fact that this ban came at the same time as the \r\n launch of Prozac. . . so?<\/em>\r\n <\/p>\r\n

\r\n We now know that Tryptophan cannot be implicated in \r\n eosinophilia-myalgia syndrome and that it was a toxic metabolite. <\/em>\r\n <\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
