What the date really means
For many supplements, the date is about potency rather than safety — the maker is indicating how long the product stays at full strength. A little past that, it may simply be less potent.
Storage matters too: heat, humidity, and light can degrade supplements faster, so a bottle kept in a steamy bathroom may not last as long as the date suggests.
When to just replace it
Trust your senses. If a supplement smells rancid, has changed color, or the texture looks off, replacing it is the safe call. There is no benefit to taking something that has clearly degraded.
Keeping track of what you have and using it consistently means less ends up forgotten and expired — Pillog helps you keep a steady routine, all on your phone with no account.
