Do Vitamins Lose Their Potency?
The way you store your vitamins can affect their shelf life and potency. Stored correctly, they will keep their potency through their expiration dates–and maybe beyond. Purchase packages that are dated well beyond the date you will finish taking the supplements, and avoid taking vitamins that have changed color or odor because they may be deteriorating. The Health Sciences Institute advises that you discard deteriorating vitamins even if it is before their expiration date.
