We are currently administering stability testing on our products to provide a more precise date based on product. This testing will reflect how well a product retains its quality over the life span of the product. Some products will include an expiration date ("Exp"), those of which have completed their stability testing.
For our products that do not yet carry an expiration date, we use manufactured dates ("Mfg"). This date will be located near the item lot number, typically on the bottom of the bottle or box/carton.
The nutritional supplement industry has been using a two-year standard for the shelf life, as dietary ingredients generally remain stable and potent for 2-3 years if properly maintained. That said, all products with a manufactured ("Mfg") date are safe for use within two (2) years of that date.
