What is the expiration date of Optimal Liposomal Vitamin C?

We do not print expiration dates on all of our products, however, we do provide the "made" date (date the product was made) for quality assurance. Unopened Optimal Liposomal Vitamin C typically retains potency and freshness for 18 months from the made date under good storage conditions, and we expect our products to conform to this standard. You can find the made date (“made”) of this product located on the bottom of the bottle.
