BioTechUSA L-Tryptophan 500 mg (60 capsules) contains the essential amino acid L-tryptophan in pure form. Each capsule provides a fixed dosage of 500 mg and is easy to take without preparation. The supplement is ideal for anyone who wants to take L-tryptophan in capsule form, without powders or shakes. The pack of 60 capsules is enough for 60 days of daily use.
L-tryptophan is one of the nine essential amino acids that must be supplemented through food or supplements.
L-tryptophan is an essential amino acid that cannot be produced by animal organisms and therefore must be obtained from external sources such as food or supplements.
L-tryptophan is found in turkey, pork, cottage cheese, eggs, and sunflower seeds.
Free amino acids do not need to be broken down from proteins first, which supports immediate absorption.
