Refund & Guarantee
Last updated: June 22, 2026
1. 30-Day Money-Back Guarantee
If a supplement isn't right for you, we'll refund your first order within 30 days of delivery. You don't need to return the product. The guarantee applies to your first order, for one item or one bundle; shipping charges are non-refundable.
The 30 days are counted from the delivery date (not the purchase date), so you have a full month to try the product.
2. How Much We Refund
We refund the full amount you actually paid for the product, including any discounts applied (for example, the QUIZ15 code or bundle savings). Refunds are issued to the original payment method. Shipping charges are non-refundable.
3. Guarantee Conditions
The guarantee covers your first order. To keep it fair for every customer, a few simple limits apply:
- one guarantee claim per customer (identified by email, payment method, and shipping address);
- the guarantee covers one item or one bundle (it does not apply to wholesale or multiple-unit purchases);
- the window is 30 days from the delivery date.
If you previously canceled a subscription and started a new one, the new order does not qualify for another guarantee.
4. How to Request a Refund
Email us at support@nanhealth.store and briefly tell us what didn't work for you. There's no need to return or ship the product back — we'll process your refund based on your request.
In certain cases we may ask for a photo of the product or what's left of it — only when there's reason to suspect abuse. We reserve the right to decline a refund where we suspect abuse or fraud, as permitted by law.
5. Damaged, Defective, or Wrong Item
This is a separate case, unrelated to the 30-day guarantee. If you receive a damaged, defective, or wrong item, email us within 14 days with a photo and we'll replace it or refund you at no cost. This applies regardless of the 30-day guarantee.
6. Refund Method and Timing
Refunds are issued to the original payment method. Processing takes a few business days; how long the funds take to appear depends on your bank.
7. Shipping and International Orders
Shipping charges are non-refundable. For orders outside the United States and Canada, shipping and any customs duties are paid by the customer and are also non-refundable. See our Shipping Policy for details.
8. Subscriptions
Your first subscription order is covered by this guarantee just like a one-time order. Subscription management and renewal terms are described in our Subscription Terms.
