We’re confident you’ll love your Onnit supplements. If the product doesn’t perform for you, however, we’re not gonna play games with you. Order any of our entry size supplements, and if you don’t like it, you can keep it! Notify our team, telling us why it wasn’t a fit for you, and we’ll get you a refund right there on the spot - no return necessary. We just ask that you try it out for at least two weeks to give it a fair shot.

Our Keep-It™ guarantee is valid for the first-time purchase of a formula, and redeemable up to three months (90 days) after the purchase date. Multiple bottles, foods, apparel and gear do not fall under this guarantee, however, they may be applicable for return.
