I purchased some rather pricey vitamins which have no expiration dates. It's an individualized system where I'm to take Magnesium Glycinate, Glucosamine Sulfat, Joint Support, and CoQ10 30 mg in the morning packets and Magnesium Glycinat, Glucosamine Sulfat, Heart Formula, and Joint Support in the evening packets.
Because these were so expensive I'd prefer to not throw them out; however, I've had them for over 3 years now. Since there is no date...can I still use them?
