As a naturopathic physician, former Chief Scientific Officer of a nutraceutical company, and member of MADE SAFE’s Scientific Advisory Board, I bring a discerning eye to clean beauty and high-quality supplements. I look beyond the label, to ingredients, formulation, and the science behind them. My recommendations consider when and how to use supplements, potential interactions with medications, and how everything fits into your care.
