Our Guarantee

Our 100-Day Guarantee

The research behind saffron and NMN runs 8 to 12 weeks. A 30-day guarantee on a product like that quietly tells you we do not believe our own citations. So we give you 100 days.

How it works

Every order is covered for 30 days from purchase. No registration, no conditions beyond the ones below, no action needed from you.

Register your bottle and that becomes 100 days. Scan the QR code on the label, or visit the registration page for your product. Register within 30 days of purchase and your window extends to 100 days from that same purchase date. Registration is at no cost and does not require you to buy anything. We show you the exact closing date as soon as you register.

Both windows run from the day you bought it, so there is no advantage to registering late. Do it while the bottle is in your hand.

If the product is not right for you inside that window, we refund what you paid for it.

The four conditions

We would rather state these plainly up front than surprise you later.

One claim per customer. The guarantee can be claimed once, ever. It exists to take the risk out of trying us for the first time.
Your first order of a product. Repeat orders and subscription renewals are not covered. If a subscription stops being right for you, cancel before your next billing date and you will not be charged.
One order, one guarantee. Registration happens within 30 days of purchase and is tied to a single order number.
Your lot number. Include the lot number printed on your bottle when you request a refund. It confirms the request relates to a bottle you actually received.

You keep the bottle

You do not need to send anything back. Opened supplements cannot be resold and are destroyed when returned, so asking you to pay postage on something we cannot use would waste your money and our time. Keep it or dispose of it as you prefer.

We refund the product price. Shipping charges are not refunded. Refunds go back to your original payment method and usually appear within 5 to 10 business days.

Starting a refund

Ordered from numilove.com

Sign in at your account.
Select the order and choose Request Refund.
Include your lot number and a sentence about what did not work.

Ordered from Amazon

Same terms. Register within 30 days of purchase to hold the full 100 days, then email hello@numilove.com with your Amazon order number and your lot number when you want to claim.

Amazon runs its own returns process on its own timeframe, which we do not set. If you are still inside their window and just want a standard return, going through Amazon is usually quicker. Our guarantee runs alongside theirs, and it is the only route open once their window has closed.

We ask for a sentence about your experience every time. It is not a condition of your refund. It is how the next formula gets better.

What is not covered

Clearance and Final Sale items.
Purchases from retailers other than numilove.com and our official Amazon storefront.
Repeat orders and subscription renewals.

Something arrived damaged, wrong, or not at all? That is not a guarantee claim, that is our mistake. Email hello@numilove.com and we will replace or refund it whatever the conditions above say, and it will not use up your one claim.

Why we do it this way

We put a QR code on every bottle so you can read the lab results for your specific batch before taking our supplements. The guarantee is the same idea pointed at the outcome instead of the ingredients. Check the batch, then check whether it worked for you, and hold us to both.

The full legal terms live in our refund policy.

Questions of any kind: hello@numilove.com. We read every message and usually reply within one business day.
