Honestly? Not really. If your bottled water looks clear and smells fine, drink up. The “expiration” is mostly marketing to keep you buying more.
But if you find a forgotten bottle from 2015 under your couch, here’s the rule: don’t take a risk for a few cents. Pour it on a houseplant instead. Your plant might love the microplastics (it doesn’t, but it’s a funny thought).
