Refund policy

60-Day Money-Back Guarantee. If your first Rivium order is not right for you, contact us within 60 days after delivery. We will refund the eligible product purchase price to your original payment method. You do not need to return the product.

This Refund & Return Policy applies to purchases made directly through riviumlabs.com in the United States.

We stand behind our products. The original purchaser may request a refund for the eligible products in their first order within 60 days after delivery if they are not satisfied for any reason.

For product safety and quality-control reasons, we do not accept physical returns of dietary supplements, including unopened products, because we cannot verify how a product was stored or handled after delivery.

You do not need to mail the product to us to receive an approved refund. Please keep or safely dispose of it. Do not send products to our warehouse unless we give you written instructions to do so.

If your order arrives damaged or defective, or you receive the wrong item, contact us within 30 days after delivery. Include your order number and, when reasonably available, a photo showing the issue. We will provide a replacement or a full refund, including any shipping charges you paid, at no additional cost.

If you contact us after 30 days, the order may still qualify under the 60-day guarantee above.

If you believe you are experiencing a serious adverse reaction, stop using the product and seek medical attention promptly. You may also report the issue to the FDA through its Safety Reporting Portal.

Please email hi@riviumlabs.com so we can document the report. If available, include the product name, lot number, expiration date, order number, and a description of what occurred. A safety report is not required to qualify for the 60-day guarantee.

Email hi@riviumlabs.com within the applicable period and include:

We usually review requests within 1–2 business days. We may ask for information reasonably necessary to verify the purchase or prevent fraud, but we will not require you to return the product unless applicable law requires otherwise.

You may cancel your subscription at any time through your online account or by emailing hi@riviumlabs.com. Cancellation stops future renewals and shipments that have not yet been processed.

If an order has already been processed, we may be unable to stop that shipment. Cancelling a subscription does not automatically refund a previously processed order. A first subscription order may qualify for the 60-day guarantee above. Later subscription shipments are not covered by the guarantee unless they arrive damaged, defective, or incorrect, or a refund is otherwise required by law.

We ship within the timeframe stated at checkout or in your order confirmation. If no shipping timeframe is stated, we will ship within the period required by applicable law. If we cannot ship on time, we will notify you and, where required, give you the choice to accept the delay or cancel the unshipped order for a full refund.

If we cancel an order or cannot fulfill it, we will refund the amount paid for the unshipped items, including applicable taxes and shipping charges attributable to those items.

The voluntary 60-day guarantee does not apply to:

• Requests submitted more than 60 days after delivery.
• Second or later orders, including later subscription shipments.
• More than one guarantee claim per customer or household.
• Free gifts, samples, or promotional items with no purchase price.
• Orders refused, abandoned, or undeliverable because the customer provided an incorrect or incomplete address.
• Products purchased from Amazon, another retailer, or an unauthorized seller.
• Claims involving suspected fraud, resale, or abuse of the guarantee.

These limitations do not affect refunds, replacements, warranties, or other remedies required by applicable law.

This policy applies only to orders placed directly through riviumlabs.com. If you purchased Rivium from Amazon or another authorized retailer, request a return or refund from that retailer under its policy.

We cannot verify the authenticity, storage, or handling of products sold by unauthorized sellers and do not extend our voluntary guarantee to those purchases, except where applicable law requires otherwise.

This policy provides a voluntary guarantee in addition to any rights available under applicable U.S. federal or state law. Nothing in this policy limits any non-waivable consumer rights or remedies. Where applicable law provides greater protection, that law controls.

Please do not mail products to this address unless we provide written authorization and instructions.
