5-HTP + B6 + Biotin + Mg from Sotya is a dietary supplement indicated for depression, asthenia, anxiety, sleep disorders, and migraines. 5-HTP is an amino acid precursor to serotonin and is manufactured by the body from Tryptophan. It increases the release of serotonin (the "feel-good" hormone) so it is used as an antidepressant, appetite suppressant, and sleep regulator (meaning better quality sleep). It has been shown to improve attention deficit and hyperactivity. Often, depression treatment consists of drugs that increase serotonin levels in the brain, improving well-being and mood. 5-HTP also helps increase serotonin levels in the central nervous system. Biotin and Vitamin B6 contribute to normal psychological function. Instructions for use: Take up to 3 capsules per day with meals. Ingredients: Griffonia simplicifolia standardized extract 20% 5-hydroxytryptophan (5-HTP) 500mg per capsule, tryptophan 150mg per capsule, vitamin B6 0.47mg per capsule, 33% RDA.
