Most things that expire, usually just loose potency (of the vitamins and minerals), other things with best before dates are usually fine for a while afterwards providing there's no mold growing or other obviously non edible shit (curdled milk). Best before and expiry dates are really just suggestions.
Wow. Can you just take a moment and realize how blessed you are? I come from a family that couldn't afford to waste food, an expiry date had no say in what we ate, unless it gave us a discount
*just expired one second ago*
So this is how it ends
