  • Essential Amino Acid - L-tryptophan cannot be synthesized by the body, but must be obtained from food or supplements, it acts as a precursor to serotonin and melatonin
  • Stress, Sleep & Mood Support - L-tryptophan can be converted to serotonin and melatonin in the body, so it plays an important role in supporting relaxation, restful sleep and positive mood*
  • Reduce Cravings - L-tryptophan is fermented from vegetable source materials and may help in reducing carbohydrate cravings*
  • Veggie Capsules - Adults take one capsule on an empty stomach 30 minutes before sleep with water or fruit juice.

Kelly's Thoughts: Tryptophan can convert into melatonin in two ways: firstly, by turning into serotonin, which then converts into melatonin, and secondly, through a more direct pathway that bypasses the lengthy conversion via serotonin, especially in darkness. This alternative route provides a quicker path to melatonin production from tryptophan.
