This is from the Medifast website: Can Medifast Meals be consumed following the expiration date? Medifast powdered products have an18-month best-if-used-by date. The Medifast Ready-to-Drink Shakes and Bars have a 12-month best-if-used-by date. This does not mean that the product will “go bad” or be harmful; it simply means that the vitamin and mineral pre-mix contained in the products may lose some of its potency, potentially rendering the product less effective. For best results, the products should be used as soon as possible and stored in a cool, dry, clean environment. Hope that’s what you were looking for!
