Does the expiry date really change a supplement’s potency?

Expiry dates are a manufacturer’s guarantee of full potency, not a cliff. Minerals are very stable; many vitamins decline slowly; sensitive ingredients like probiotics and omega-3 oils are the most time- and storage-sensitive. Stored cool and dry, most supplements remain effective up to their printed date. That’s why we show the exact expiry of each lot — and offer shorter-dated stock at a smarter price for routines you’ll finish soon.
