Expired supplements?

[Mrshawwk]

This is ridiculous, I know, but I have some zinc that expired in 2004. So. is it a) so stale no zinc is left in it, or b) actually toxic or rancid or c) just fine, probably has lost some of its potency, but still good.

What about other supps? Do you throw them out on their "due dates", or ignore the dates all together?

I'd say its no good. Thats way to many years ago! Since zinc is super cheap anyway, I'd just get another one. I had some zinc I used that expired a few months before and I used it but 4 years is too long. Supplements do loose there potency over time.
