Refund policy
Last updated: August 24, 2026
30-day money-back guarantee
If Cristae NMN 500 is not right for you, email us within 30 days of delivery and we will refund your order in full — the product and what you paid for shipping. Opened or unopened. You do not need to send the bottle back; there is nothing for us to do with a returned supplement except discard it, so keep it or bin it as you prefer.
We would rather refund you than argue with you. A brand whose whole argument is that it tells you exactly what is in the bottle cannot then make it hard to get your money back.
Damaged, wrong, or missing orders
Separately from the guarantee, if your order arrives damaged, arrives as the wrong item, or is confirmed lost in transit, we will replace it at no cost or refund it in full — your choice.
- For a damaged or incorrect item, contact us within 30 days of delivery and include a photograph of the item and its packaging.
- For a package that never arrived, contact us within 30 days of the estimated delivery date.
The photograph is not us being difficult — our fulfilment partner requires it to approve a replacement at their cost, and sending it up front saves a round trip.
Limits
The money-back guarantee is intended for people trying the product for the first time. It applies to one order per customer and per household. We may decline a refund where there is a clear pattern of repeat ordering and refunding, or where an order was placed for resale. This does not affect the damaged, wrong, or missing cover above, which always applies.
What we do not cover
- Incorrect shipping addresses. If an order is undeliverable because of an address entered at checkout, we can ship a replacement, but the reshipment is at your cost.
- Unclaimed packages. If a carrier makes its delivery attempts and the package is returned to sender unclaimed, reshipment is at your cost.
- Refused customs or import charges on any order shipped outside the United States.
Cancelling an order
Orders move to our fulfilment partner quickly. Email us as soon as you can — if the order has not yet been accepted for fulfilment, we will cancel it and refund you in full. Once it has been accepted, or once it is with the carrier, we can no longer cancel or redirect it. At that point the 30-day guarantee above covers you anyway.
How to make a claim
Email njt1120@gmail.com with your order number and a sentence about what went wrong — plus a photograph, if the item arrived damaged or incorrect. We aim to reply within two business days. You do not need to give a reason to use the money-back guarantee.
How refunds are issued
Approved refunds are returned to the original payment method. Once we issue the refund, your bank or card issuer typically takes 5–10 business days to post it. We cannot refund to a different card or account than the one used to pay.
Your legal rights
Nothing in this policy limits any rights you have under applicable consumer protection law, including any rights regarding products that are faulty or not as described.
