L-Tryptophan, an essential amino acid, is a precursor to serotonin ("the happiness hormone") and vitamin B3. Low tryptophan levels can negatively impact mood and behavior, contributing to depression and anxiety. This supplement helps alleviate emotional tension, anxiety, and promotes a positive mood. Serotonin plays a crucial role in regulating the central nervous system and sleep-wake cycles. L-Tryptophan is used to combat insomnia and sleep disorders, improving sleep quality and reducing interrupted sleep. It may also help alleviate premenstrual syndrome (PMS) symptoms and support smoking cessation. Essential for protein synthesis, L-Tryptophan contributes to increased physical endurance, improved work performance, and enhanced strength. Each capsule contains 500mg of L-Tryptophan. 90 capsules per bottle.
