L-Tryptophan is an essential amino acid for humans and animals, since it can't be produced naturally by the body. Tryptophan is converted to 5-hydroxytryptophan (5-HTP) in the brain, which produces serotonin. Additionally - L-tryptophan aids in the production of melatonin, and kynurenine.

This amino acid acts as a natural mood regulator due to its ability to help the body produce and balance certain hormones naturally.

Key Points:

  • May promote serotonin and melatonin production

  • May improve sleep & circadian rhythm
  • May promote brain health
