What is the correct procedure for storing supplements?
USANA’s Nutritionals, Foods, and Sense Products should all be stored in a cool, dry location. Although not required, refrigeration can help extend the shelf life of USANA products. (OptOmega is an exception to this rule, as it must be refrigerated after opening.)
Because some nutrients are susceptible to heat, do not expose USANA products to excessive heat for a prolonged amount of time. (Heat exposure during shipping is not generally significant enough to affect product quality.)
