One thing you may have been concerned about was the expiration date on those bottles.
Placing a vitamin or medication in a cool and dry place will help it remain potent for many years. It is important for us to know this and have good supplements on hand in the case of emergencies. Read on, because you will be surprised how long they last.
Although mandated for over-the-counter and prescription medications, the FDA does not require supplements to have expiration dates. But, many vitamin and supplement makers voluntarily list expiration dates to express how long a product is guaranteed to retain its highest level of potency. Manufacturers will not make recommendations about the stability past the original expiration for legal and liability reasons.
