Vitals L-Tryptophan

Vitals L-Tryptophan
In nature, there are approximately five hundred amino acids. 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.

Tryptophan 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.

Tryptophan 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.
