Unlike other retailers, when it comes to quality vitamins and supplements, we don’t just talk the talk—we research, take a fine-tooth comb to, and deliberate over each ingredient allowed in the supplements we carry on our shelves. We never take lightly the fact that you’ve trusted us with your health—and that’s why all the supplements we carry go through a rigorous screening process by our quality standards experts. If we won't take it, you won't find it here. In fact, what you won’t find on our shelves is as important as what you will find. We've put together a growing list of the most problematic supplement ingredients, many of which are still commonly found in supplements at other retailers and online—but never here.
As new research becomes available, an ingredient that might not have been considered problematic may now be an ingredient of concern or unacceptable. Read more about grandmothered and limited ingredients.

*We work hard to keep the information on our “Things We Won’t Carry and Why” lists accurate and up to date. However, there are times where an ingredient on these lists may appear in one of our products. As an example, manufacturers may reformulate their products, leading to changes in ingredient lists that could temporarily allow an excluded ingredient to appear in products on our shelves.
