We place a top priority on probiotic potency and perform routine testing to ensure our products meet or exceed stated potency on the label up until the "best by" date.
Each batch of our probiotics is designated a lot number with which you may contact customer service for a specific "best by" date. You can call us at 1-800-524-8802 and choose "0" for the next customer service representative to assist you.
Why don't you use the term "expiration date" or "expiry date" or "expires by"?
Over time, probiotics may begin to decline in potency and may drop below the stated label potency after the "best by" date, but customers can still benefit even if the potency is no longer at 100%.
