Expired vitamin C

I’ve got a couple of big bottles of vitamin C that have since expired, 11/02. Does anyone know if they’re still good? Thanks.

There are too many factors involved from how they were stored to air contamination. Personally, unless I was who stored the product past the expiration date (like I have for many ephedrine products), I would toss the shit and buy more vitamin c.

Is it ascorbic acid or a real natural source C?

Either way, I agree with the professor but get some real vitamin C this time not that ascorbic acid bs
