For how long after the manufactured date is the product good?

The products are designed to meet their label claims for at least 2 years, barring any highly unusual treatment such as leaving the container open for more than a few minutes. Once opened, the container should be re-closed tightly, stored in a cool place (though not refrigerated), away from excess moisture and not exposed to direct sunshine. It is best to consume products within 30-90 days of opening.
