NOW Foods L-Tryptophan 500mg 60 Veg Capsules

NOW® L-Tryptophan supplies 500 mg of free-form L-tryptophan in each veg capsule. Tryptophan is an essential amino acid — one your 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 as part of an evening routine.*

About the key ingredients

• L-Tryptophan (free-form) – 500 mg: An essential amino acid and the original precursor to serotonin and melatonin, encouraging a positive mood and promoting restful sleep.*
• Other ingredients: Cellulose in a plant-based hypromellose (vegetarian) capsule, with no artificial fillers.

Who it's for

NOW® L-Tryptophan is well suited to adults seeking natural support for a positive mood and restful, quality sleep, particularly as part of an evening wind-down routine. As the original precursor in the pathway to serotonin and melatonin, it appeals to those who want to support both daytime mood and nighttime rest from a single essential amino acid. It's typically taken on an empty stomach, away from protein-containing foods, for the best effect.*

Suggested use

Take 1-2 capsules 2 to 3 times daily on an empty stomach, with final dose at bedtime, or as directed by your physician. Store in a cool, dry place after opening.
