Thorne cares deeply about where our ingredients come from. Our research and development team is tasked with sourcing exceptional ingredients, maintaining oversight of an ingredient's origin, and providing complete supply chain transparency.
We partner only with suppliers whose practices emphasize quality, science, and environmental responsibility. We believe that better ingredients mean better potency, absorption, and digestibility - and ultimately better health.

At Thorne, clean describes supplements that do not contain any harmful or unnecessary ingredients. Our "No" List guides us every day in choosing which ingredients to source and how to formulate new products, so you can feel confident about what you are putting in your body.See our No List
