Does the window run from the purchase date or the delivery date? On a 60-day guarantee, shipping time can quietly consume a week of it.
Check which one applies and put the deadline in your calendar the day the order confirmation arrives. That single habit prevents most missed windows.
This is the one that separates real guarantees from decorative ones. A guarantee that only covers unopened jars is not a satisfaction guarantee — you cannot become dissatisfied with a product you never used.
Look for explicit language covering opened or partially used product. If the terms are silent on this, ask support before ordering rather than after.
Return shipping on a bulk order is not trivial. Some guarantees cover it, some do not, and some require tracked shipping at your expense with proof of delivery.
Less common in supplements than in electronics, but worth checking. A 'full refund' minus a restocking fee is not a full refund.
Guarantee length is a signal about the mechanism a brand believes in. A 14-day guarantee suits a product with acute effects. A 60-day guarantee roughly matches the lower bound of the research window for adaptogenic and botanical formulas.
A brand offering 60 days on a botanical formula is aligning the guarantee with the timeline it is asking you to commit to — which is the coherent thing to do. See our terms for the specifics on this product.
Save the order confirmation email, note the order number, and photograph the jar and lot number before you start. If you ever need the guarantee, having all three ready turns a frustrating process into a short one.
