Bee Pollen expiration?

[Mark]

I've come across a jar of Natural Brand Chewable Bee Pollen
tabs. Expiration date is January 1995. I'm wondering if these
have lost potency. the product contains no preservatives, no
artificial colors or flavors and is sodium free. it contains
Bee Pollen in a base containing Bee Propolis and royal jelly.
it does contain fillers Fructose, Dextrates and Cellulose
binders. label also says, "EXCIPIENTS: Stearic Acid, magnesium
Stearate, natural Flavors, Silica.

I'm just wondering if these should bed tossed or if they would
still have any benefit.

Thank you.

Mark
