Twenty of these are amino acids that serve as building blocks for proteins in the human body, referred to as 'essential amino acids'. These essential amino acids can be further divided into the categories of 'essential', 'semi-essential', and 'non-essential'. L-tryptophan belongs to the so-called essential amino acids, meaning that the body cannot produce it from other amino acids, and one is completely dependent on diet to meet daily needs. \r\u003cbr\u003e\r\u003cbr\u003eTryptophan is present in food in too small amounts to be used as a source for the production of supplements. Therefore, tryptophan for use in a supplement is typically produced through a specially developed fermentation process. Microorganisms can synthesize tryptophan themselves, and this property is utilized in this process. The natural L-form of tryptophan is produced. The synthetic D-form is ineffective and can reduce the bioavailability of the natural L-form. Supplementation with D-tryptophan is therefore not recommended.\r\u003cbr\u003e\r\u003cbr\u003eTryptophan is, among other things, the precursor of niacin (vitamin B3), 5-HTP (5-hydroxytryptophan), the neurotransmitter serotonin, and the hormone melatonin. It can cross the blood-brain barrier, but is sensitive to competition with other amino acids. A tryptophan supplement should therefore preferably be taken on an empty stomach, away from other amino acids.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eComposition\u003c\/b\u003e\u003cbr\u003e\u003ctable border=\"1\" cellpadding=\"1\" cellspacing=\"1\" style=\"width:500px\"\u003e\n\t\u003ctbody\u003e\n\t\t\u003ctr\u003e\n\t\t\t\u003ctd\u003e\u003cstrong\u003eComposition per capsule (daily dosage):\u003c\/strong\u003e\u003c\/td\u003e\n\t\t\u003c\/tr\u003e\n\t\t\u003ctr\u003e\n\t\t\t\u003ctd\u003eL-Tryptophan\u003c\/td\u003e\n\t\t\t\u003ctd\u003e400 mg\u003c\/td\u003e\n\t\t\u003c\/tr\u003e\n\t\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eIngredients\u003c\/b\u003e\u003cbr\u003eL-tryptophan, rice concentrate (oryza sativa), vegetarian capsule (pullulan, from fermented starch), rice extract (oryza sativa).\u003cbr\u003e\u003cbr\u003e\u003cb\u003eUsage\u003c\/b\u003e\u003cbr\u003eAs a dietary supplement for adults, take 1 capsule per day between meals (at least half an hour before or two hours after a meal) or before bedtime with water.\r\u003cbr\u003e\r\u003cbr\u003eNote:\r\u003cbr\u003eWhen using medications that affect brain metabolism, such as antidepressants and sedatives.
