Scientific. Evidence-Based. Committed. Health Support. 

It is who we are and what we do.

Brain health, gut health and overall health are tied together in a variety of ways; we are committed to supporting this association with scientifically researched, evidence-based, consistent, reliable nutrients known to promote overall well-being. Our amino acid formulas support the enzymatic balance between serotonin and the catecholamines (dopamine, norepinephrine and epinephrine). With the addition of CysReplete, which supports glutathione, we offer a brain and gut approach to health that promotes this interconnected understanding of optimal health.
