Return & Refund Policy

At NMN, we want you to be fully satisfied with your purchase. Because we deal with high-purity dietary supplements, we maintain a strict return policy to ensure the safety and quality of our products for all customers.

Returns

Window: You have 30 days from the date of delivery to request a return.

Condition: To be eligible, your item must be unopened, unused, and in its original packaging with the safety seal intact. We cannot accept returns on opened bottles due to health and safety regulations.

Proof of Purchase: A receipt or order number is required to process your return.

Damages and Issues

Please inspect your order upon reception. If the item is defective, damaged, or if you receive the wrong product, contact us immediately at Nmnsupps.support@gmail.com so we can evaluate the issue and make it right.

Refund Process

Once we receive and inspect your returned item, we will notify you if the refund was approved.

Approved Refunds: You will be automatically refunded on your original payment method within 5–7 business days.

Shipping Costs: Customers are responsible for paying their own shipping costs for returning items. Shipping costs are non-refundable.

Exchanges

The fastest way to ensure you get what you want is to return the item you have, and once the return is accepted, make a separate purchase for the new item.
