Vitals L-Tryptophan 60 Capsules

Vitals L-Tryptophan
Approximately five hundred amino acids occur in nature. Twenty of these are amino acids that serve as building blocks for proteins in the human body; these are referred to as ‘fundamental amino acids’. These fundamental amino acids can be further divided into the categories ‘essential’, ‘semi-essential’, and ‘non-essential’. L-tryptophan belongs to the so-called essential amino acids, which means that the body cannot produce them itself from other amino acids, and that to meet daily needs, one is entirely dependent on diet.

Tryptophan occurs in food in quantities too small to be used as a source for the production of supplements. Tryptophan for use in a supplement is therefore usually manufactured by means of a specially developed fermentation process. Microorganisms can indeed synthesize tryptophan themselves, and this property is utilized in this process. This produces the natural L-form of tryptophan. The synthetic D-form is not effective 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 to niacin (vitamin B3), 5-HTP (5-hydroxytryptophan), the neurotransmitter serotonin, and the hormone melatonin. It can cross the blood-brain barrier but is susceptible to competition from other amino acids. A tryptophan supplement should therefore preferably be taken on an empty stomach, separate from other amino acids.
