Do IN products have an expiration date?
Most of our products have a shelf life of 2-3 years provided they are kept in normal temperatures and the inner blister pack is not torn or broken. Even after 2-3 years our products DO NOT become toxic, but the nutritional value percentage would not be guaranteed. Each product has a series of numbers and a letter that determines the date it was manufactured. There are lot codes on each package of an Intelligent Nutrients product.
