Shelf Life and Expiration Dates
Table of Contents
Even though nutritional supplements contain expiration dates, unlike like perishable foods like milk or meat, they don’t really spoil or go “bad” in the same way. When discussing the shelf life of a supplement, it is really the potency that is the primary concern, not ingredient spoiling or becoming toxic. It isn’t dangerous to take expired vitamins, but they may have lost some potency.
The expiration date represents the last day the item will be at its highest level of potency and quality. In other words, up until that date the product is guaranteed to contain its labeled ingredient potencies and the tablet itself is guaranteed to disintegrate properly. Beyond the expiration date, nutrient potency may gradually decline. As such, we recommend consuming products before the printed expiration date.
Storing USANA Products
Some vitamins are very sensitive to the elements, while others (ie. minerals) will remain potent almost indefinitely. We recommend storing supplements below 25 degrees Celsius (room temperature), and away from light and heat. Refrigeration may also help increase the shelf life of supplements. Storing your supplements properly ensures that your supplements will remain fully potent and of guaranteed quality for entire labeled shelf life.
