NOW Foods L-Tryptophan Powder 2 oz

NOW® L-Tryptophan Powder supplies pure, free-form L-tryptophan with no fillers. Tryptophan is an essential amino acid — one the body must obtain from the diet — and it is the original precursor in the pathway that leads first to 5-HTP, then to serotonin (a neurotransmitter tied to mood and relaxation), and ultimately to melatonin (the body's sleep hormone). Because it feeds this entire pathway, tryptophan is valued both for encouraging a positive, balanced mood and for promoting restful, quality sleep. The adjustable powder is typically mixed into water in the evening.*

Cautions & interactions

As with any supplement, talk to your doctor before adding this product to your routine if you are pregnant or nursing, taking prescription medication, or managing a health condition. Keep it out of reach of children, store in a cool, dry place, and don't exceed the recommended serving. If you take a multivitamin or several supplements, review the combined amounts with your healthcare provider so you don't unintentionally double up on the same nutrient.
