Check the expiration date on your vitamin supplements for the first indication of how long they'll last. Vitamin supplements typically bear an expiration date of a year or so from the time they're manufactured. If you store them properly, they should stay potent for at least this long. After the expiration date, you can still expect to use them without harm, but there's no guarantee on potency.
Buy vitamins in small quantities so they stay fresh and potent. Check the expiration date on your vitamin supplements for the first indication of how long they'll last. Vitamin supplements typically bear an expiration date of a year or so from the time they're manufactured. If you store them properly, they should stay potent for at least this long. After the expiration date, you can still expect to use them without harm, but there's no guarantee on potency.
