We state a “five-year shelf life” solely because most food supplements bought, are taken far within five years. Considering it is a complex carbohydrate, our product is virtually imperishable.
For example, a bag of sugar can be stored for close to a decade; as long as it didn’t get wet, it will still be just as good in your coffee the next morning. That is the very nature of complex carbohydrates; they are nature’s armor when it comes to Plants and Fungi. As long as Beta Glucan is stored dry at room temperature, I would say its shelf life is virtually indefinite. Moreover, we have done shelf life studies where we demonstrate the Biological Activity remaining stable even after five years.
