• Encourages Positive Mood
  • Promotes Restful Sleep

L-Tryptophan is an essential amino acid; therefore, it is not synthesised by the body and must be obtained from the diet. L-Tryptophan is critical for the production of serotonin and melatonin, which help to support a positive mood, healthy sleep patterns, and proper immune system function. Every lot of NOW® L-Tryptophan is tested to be free of Peak E and microbial contamination.


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.
