My order came in a timely manner and as ordered. I have not had the products but a couple of weeks. I purchased the Pure MNN powder. The powder simple to take and am already feeling an increase in energy. Looking forward to the next few months.

Great Products, Poor Website Experience: A Long-Time Customer's Perspective
Over the years, my attitude toward NMN has shifted from skepticism to confidence largely because of the excellent products from RENUE By Science and the genuine care the company showed its customers in the early days. I have continued to use this brand despite the many competing products that have appeared on the market.
The only reason I am now considering trying other brands is the change that began last year in how the official website handles ordering and customer service. For international customers, the experience has become quite unfriendly: checkout is forced through services like Shop and PayPal that rely on unfavorable exchange rates, and the system adds speculative taxes based on assumptions tied to the shipping address that could have been avoided. In addition, my sessions are automatically and forcibly redirected to the Australian regional site, which is not what I want.
Taken together, these changes make the shopping experience feel as if the company has no interest in retaining loyal customers. The reason for writing this review is that I truly like the products but am deeply dissatisfied with the purchasing process, and I hope these issues can be addressed and improved in the future.

Received Very OLD NMN
Ordered a large quantity of NMN - only to find out it was produced 2 YEARS (based on product date stamp) prior to receiving. They should be more transparent about such things. I submitted a review post regarding it on their site - but apparently they don’t take reviews that aren’t great because it NEVER showed up on the review scroll. The entire experience let me know I had to stop ordering my supplements from them.

Thanks for the response. I agree, Renue by Science needsto provide better communication about the shelf life of their products. Unless I'm purchasing wine or cheese- I don't typically want to purchase anythong I am consuming - especially supplements, that have been sitting that long. Efficacy is immediately questioned - which no one wants when the products aren't cheap.

Good company to deal with
Long story short what was advertised was different to what I received but to the credit of this company they were on the front foot took responsibility for the mistake and have changed the website information to be in line with what the product offers.

The item came quickly and was as expected. I am not sure I am noticing any results (NMN) purchase but it has only been a few weeks.
A company that delivers more than fancy marketing
My husband and I trust and like Renue By Science. We use the Liposomal NMN with Resveratrol and also the facial serum and would use other products but they are too costly for our budget. That said, my husband and I are in our 60’s and continue to live a very athletic lifestyle with minimal wear and tear to our bodies and no health issues. We don’t even have gray hair, so we have to think the NMN is working. We listened to a podcast about 8-10 years ago featuring Dr. David Sinclair and have been using NMN since and plan to continue.
We appreciate the ongoing research done by Renue by Science in their quest to provide products that are well absorbed and therefore more effective. We feel this is particularly important with NMN because it used to have a fairly low absorption rate.
I could go on, but suffice to say while most people our age are fairly sedentary and have resigned themselves to occupying their time by looking at the TV and and their phones, we have not lost our muscle tone or fitness level (or hair), and the TV in our house only comes on so our 2 year old grandson can get his Sesame Street fix before we take him for a hike :)
I bought the time release NMN tablets
I bought the time release NMN tablets, but they bothered my stomach, I wrote to inquire about getting a different form and promptly received a suggestion for one. I bought that, and was refunded right away for the other bottle!! Fantastic customer service!!! Very pleased
