Dietary supplements: Storage counts

By Mayo Clinic Staff

Keep dietary supplements, such as vitamins, in a cool, dry place. Avoid hot, humid storage locations, such as in the bathroom. Also keep an eye on expiration dates. Supplements can lose potency over time. If a supplement doesn't have an expiration date, don't buy it. If your supplements have expired, discard them.
