Are vitamins still effective enough four months after the expiration date?
• Q: If vitamins are four months out of date, are they still effective enough to do their job? It is a one a day. • A: Medications, vitamins, and supplements should never be used after the expiration date on the container has passed. They can lose their potency and potentially become dangerous once past their expiration date. Expired medications should be disposed of properly. Contact your local waste management company or local pharmacist for disposal guidelines in your area.
