What is the expiration date of Optimal Liposomal Active B12 with L-5-MTHF?

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 liquid supplement products typically retain potency and freshness for about 1 year from the manufacture date under good storage conditions. You can find the “made” date of this product located on the bottom of the bottle.
