Founder of IngredientMD, a supplement intelligence platform powdered by most clinical data available. What's important, we communicate in language humans will understand instead.

I focus on bringing evidence-based analysis to consumer supplement decisions.

I've dedicated my life to fixing gut health issues, balancing hormones, and tackling heart and energy problems from the root cause—not just masking symptoms with endless meds.
