Reviewers overwhelmingly had a great experience with this company.

Consumers appreciate the purity of the products, often noting that the benefits justify the higher price point compared to competitors. The fast and reliable delivery service is also a recurring positive point. Many consumers report satisfaction with the company's handling of issues, such as incorrect orders or transit problems, with quick and helpful customer service.

Great products, bad customer service

Great products, terrible customer service. They lied to me about what happened to my missing parcel saying it got lost in Canada and that it was because Canada Post was not operating. FedEx called me today to tell me my package was missing since September (almost a month later) and it was either lost in Hong Kong where it shipped from or in Memphis in the USA. I’m in Canada so I was shocked that my product would be shipped from Hong Kong and then to the USA then to Canada. I’m also very concerned about where products are made. The customer service was rude and dismissive and as I found out today- dishonest. You can see in the response below that they continued to tell me a different story. Very disappointing as I loved this company and recommended it to friends and family

Given the timing of responses - I believe their customer service is now based in Hong Kong and none of their phone numbers work nor the live chat so they have clearly cut costs on customer service. Don’t believe their money back guarantee because you can’t get in touch with anyone during regular USA business hours.

We’re very sorry for this customer’s frustration. The customer reached out regarding an order that stopped tracking after leaving the United States. After contacting our shipping partner, we determined the package was lost or stolen and issued a full refund. The customer was dissatisfied with this resolution. We are reviewing the interactions with our customer service team to identify ways to improve communication moving forward, and we sincerely apologize for the inconvenience.

Update: To address the customer’s concern about where our products are made: all products, including those shipped from our Hong Kong warehouse, are manufactured in the United States. They are identical items from the same production batches. Some international orders are fulfilled from Hong Kong to provide more affordable shipping rates. We sincerely apologize for any miscommunication regarding the loss of your item and are actively working with our carrier to determine what happened. Your refund should appear within 5 business days.

Is this even worth it?

I got an email recently that introduced the idea of NAD not working to its fullest potential on its own. Purchasing additional supplements is not in my budget currently so this was discouraging. Am I buying the NAD in vain? Is it working? Should I stop taking it if it’s not effective? Why not add them all together? Why make customers by 2-4 different supplements in order for the initial supplement to be effective? Now I’m questioning myself every morning when I take my NAD.

We appreciate this customer’s feedback and understands the confusion. Renue would like to clarify that it does not sell an NAD+ supplement on its own. Our NAD+ Complete formula combines NAD+ with key precursors, NMN, NR, and Trigonelline, providing a comprehensive approach to raising NAD+ levels effectively.

There is no need to purchase additional supplements to experience the benefits of increased NAD+. Some customers choose to add other products for further optimization, but this is entirely optional.

We encourage the customer to reach out directly to the support team at support@renuebyscience.com or call 1-800-810-1935 (Mon–Fri, 9 AM–5 PM EST) for a clear, personalized explanation and to ensure all questions are fully addressed.

We sincerely apologize for the customer’s disappointing experience. The package should have arrived securely sealed, and we’re currently investigating why this occurred. The customer has been fully refunded, and improvements to packaging materials and handling are being implemented to prevent future issues. We truly appreciate the feedback.

The claim is legit and I am only getting younger. Don't forget to eat healthy and exercise. This is not a magic pill.

Disappointed with the delivery and how it was organized.
The product containers were packed in a thin plastic bag, which was clearly thrown and mishandled. One of the containers arrived cracked.
Then began a long process of back-and-forth with customer service / AI — long waiting and endless messaging.
It took a whole week to replace the broken container and several more days of pointless, outdated correspondence. Eventually, I received a refund.
As for the product itself — I have no idea. Let’s assume the product is excellent, but the second part — delivery and customer support — is primitive and fails to meet the standards expected from a service of this kind.

We are very sorry to hear about this customer’s experience with shipping and communication. While rare, we understand how frustrating it can be when a package is mishandled during transit. The customer was fully refunded, and we’ve since reviewed packaging and customer-service processes to help prevent similar issues. We appreciate the feedback and are glad the matter was ultimately resolved.

Enjoyed talking to Grant when he had time to talk. Meds arrive on time. Probably benefit from NMN in terms of energy.

One recommendation: put some marking on your capsules, if only a letter, to distinguish one med from another. Currently they all look the same and can become confused one for another if not careful (e.g.,for people who lay out and repackage their pills each week)
