What's the best way to store vitamins and minerals?

Answer by:

Light, moisture, and excessive heat can reduce the potency of vitamins and mineral supplements. So the best place to store supplements is in a cool, dry location -- in a kitchen pantry or a bedside table, for instance. Don't refrigerate vitamin and mineral supplements. Taking them from refrigeration to room temperature can cause condensation inside the bottle. Certain non-vitamin supplements should be refrigerated, however. Labels usually indicate when a supplement should be kept in the refrigerator. In the case of all supplements, it's always a good idea to check the expiration date.
