Returns & Refunds
We stand behind every batch we make. If a CoreLabs product isn't right for you, we'll make it right.
Our 90-day satisfaction guarantee
Every CoreLabs product is covered by a 90-day money-back satisfaction guarantee. You have 90 days from the delivery date to request a refund — even if the bottle is opened and empty.
Supplements take time to work. Ninety days is roughly how long it takes to know whether something is doing anything for you, so that is how long you get to decide.
You do not need to ship the product back to us. For safety and cGMP compliance, returned supplements cannot be restocked or resold, so we ask you to dispose of anything remaining rather than pay to ship it. We'll process your refund without a return.
To request a refund, email support@corelabs.co with your order number.
Unopened product
Unopened, unused product in its original sealed packaging may be returned within 90 days of delivery for a full refund of the purchase price.
- Contact us first at support@corelabs.co for a return authorization. Returns sent without authorization may not be processed.
- Return shipping is at your expense unless the return is our error.
- Original shipping charges are non-refundable.
If we got it wrong
If your order arrives damaged, incorrect, incomplete, or defective, we cover everything — replacement or full refund, your choice, with no return required and no shipping cost to you.
Contact us within 30 days of delivery and include your order number and a photo of the product and packaging showing the lot number and expiry date printed on the label. The lot number lets us trace the batch against our retained samples and Certificate of Analysis, so we can fix the root cause rather than just the order.
Subscriptions
You can cancel any subscription at any time, with no fee and no cancellation call.
- Manage or cancel in your account, or email support@corelabs.co
- Cancel at least 48 hours before your next scheduled charge to avoid being billed for that shipment
- If you cancel after an order has already been charged and fulfilled, that shipment is covered by the 90-day guarantee above
- You may skip, delay, or change the frequency of any subscription at no charge
We email you before each renewal, and every renewal email includes a one-click cancellation link.
Refund processing
Approved refunds are issued to your original payment method. Refunds are processed within 3 business days of approval. Your bank or card issuer may take a further 5–10 business days to post the credit. You'll receive an email confirmation when the refund is issued.
Purchases made on Amazon
Orders placed through Amazon are governed by Amazon's return policy and must be returned through your Amazon account. We can't process refunds for Amazon orders directly. If you have a product quality concern about an Amazon order, please still contact us — we want to know, and we'll help however we can.
Damaged in transit
If a package arrives visibly damaged, photograph it before opening if you can. Contact us within 7 days of delivery and we'll replace the order at no cost to you.
Exceptions
We may decline a refund where the request falls outside the applicable window, where there is evidence of fraud, resale, or repeated abuse of this policy, or where the product was not purchased directly from CoreLabs or an authorized retailer. Products purchased from unauthorized third-party sellers cannot be verified as genuine or as having been stored correctly, and are not covered.
