First let’s explain what the expiration date on our supplements actually does. Unlike milk or bread, the dried herbs, vitamins, and probiotics in our formulas never become unsafe to consume as long as they are stored properly. Our expiration dates are based on potency and effectiveness, rather than safety. Legally, our labels must reflect what is in the bottle, and probiotics and vitamins lose potency over time. So our expiration dates reflect how long we can guarantee the information on the label.
Because of this, our first lot of Intelligut had a Born On date, because the shelf life for the probiotics is 2 years, and the herbs is 4 years. Feedback from customers and retailers let us know that this caused confusion, so we updated it to reflect the 2 year shelf life in subsequent lots.
