SKU: N/A Category:

Advanced Serotonin Formula

Supports Healthy Sleep & Mood

Amino acids simply cannot do their job when one or more of the essential “helper” nutrients is missing.

L-Tryptophan Complete advances the science of amino-acid metabolism by identifying the coenzymes and cofactors that work with L-Tryptophan to promote and sustain serotonin.*

In addition recent research shows that curcumin helps slow the breakdown of serotonin into inactive metabolites. We believe no other L-Tryptophan formula is so complete or so thoroughly-researched.

Contains no gluten, yeast, wheat, rice, corn, soy, dairy,  eggs, peanuts, fish, shellfish, sugar, artificial color or artificial flavor. Non-GMO. 

DIRECTIONS (Adults): Take one (1) to three (3) capsules or as directed by a health professional.  Best if taken at bedtime or between meals. For children, consult a health professional.
