L-Tryptophan

L-tryptophan is an essential amino acid, meaning the body cannot produce it on its own and must obtain it through diet or supplementation. It is found naturally in protein-rich foods such as turkey, eggs, soy, dairy products, and pumpkin seeds. L-tryptophan plays a central role in the synthesis of serotonin, a neurotransmitter involved in regulating mood, sleep, and appetite. It is also a precursor to melatonin, the hormone that helps regulate the sleep-wake cycle. Additionally, tryptophan contributes to the production of niacin (vitamin B3), which is essential for energy metabolism. An unbalanced diet, chronic stress, or certain life stages can reduce tryptophan intake. L-tryptophan supplementation is intended for those who wish to support their emotional balance and contribute to satisfactory sleep quality, as part of a healthy lifestyle.
