Product Details
Best L–Tryptophan products contain Ajinomoto TryptoPure™. Tryptophan is an essential amino acid readily converted by the body to the neurotransmitter serotonin. Able to cross the blood–brain barrier, L–tryptophan is altered by enzymes to first form the intermediate amino acid 5–HTP and then serotonin. It is also the metabolic precursor to melatonin and to the B vitamin niacin. Supplementing the diet with pure L–tryptophan like TryptoPure™, found in Doctor Best L–Tryptophan products, can improve sleep and enhance mood, and may also be beneficial in reducing carbohydrate cravings.
What is Ajinomoto TryptoPure™?
TryptoPure™ is pure, pharmaceutical–grade L–tryptophan produced by the world's leading maker of amino acids Ajinomoto. The global leader in the research, production, and sales of amino acids, Ajinomoto was one of the first to make pharmaceutical–grade amino acids; they literally invented the process.
Ajinomoto TryptoPure™ is considered the purest, most trusted L–tryptophan available. It is manufactured via fermentation strictly from vegetable sources, not animal, and it is between 99% and 100% pure. The level of impurities in tryptophan from other makers can be much higher.
In fact, from 1989 to 2006 the FDA was so concerned about the quality of tryptophan coming into the U.S., that it instituted an import ban with one exception: Ajinomoto's TryptoPure™. In 1989, the importation of L–tryptophan was banned in the United States after cases of an autoimmune illness called eosinophilia–myalgia syndrome were traced to an improperly prepared batch of tryptophan. The FDA limited L–tryptophan availability to prescription drugs, infant formulas, and enteral feeding products. Because the FDA recognized the unsurpassed quality Ajinomoto TryptoPure™, it was excepted from the ban, but its use was limited to those few products. Today, it is available over–the–counter in Doctor Best L–Tryptophan products.
