Beware of fake NMN being sold online including amazon, ebay, aliexpress

Over the past few years there have been several reports of fake or low-quality longevity and anti-aging supplements namely Nicotinamide mononucleotide (NMN) being sold online on sites like eBay, Amazon, AliExpress, it’s not surprising given the public interest generated by David Sinclair’s Book along with the high price of legitimate NMN. These unscrupulous companies are selling products that claim to be NMN with no or very little of the active ingredient, what’s worse many of these products can contain unacceptable levels of heavy metals and arsenic.

In 2022 ChromaDex the manufacturer of TRU NIAGEN tested 21 brands of NMN available on Amazon, 14 were found to contain less than 1% of the claimed NMN content, a screenshot of the results can be seen below. While its great that ChromaDex has paid up for this testing and subsequent report, it should be noted active ingridient of TRU NIAGEN is Nicotinamide Riboside (NR), which makes me wonder if the objective of this report was purley marketing to muddying the waters of NMN, however it has exposed the bad practices of some companies and highlights the point extra checks should be taken (see my checklist below) when purchasing any supplement. Here is a link to the report

In 2021 ProHealth Longevity teamed up with their supplier Effepharm Ltd (the producer of Uthever NMN) to analyse the quality several brands of NMN for sale on Amazon surprisingly more than 50% contained no NMN and many had less than 80% purity. Link to article

In February 2022 published an article detailing a web of brands selling NMN, Liposomal Glutathione and Resveratrol all associated to Serumlab S&C International LLC, in this case all the brands associated to Serumlab S&C International LLC were tested and found to have no or very little of the ingredient listed on the bottle.

How to spot fake Longevity supplements including NMN

While its great to have the resources to be able to test the purity and safety of supplements, its  usually only possible for companies and wealthy individuals, which is why I have outlined a few of the things you can look for to assess if the NMN or any supplement for that matter is good to purchase.

  • Does the product listing have a recent Certificate of Analysis (COA) for both purity and heavy metals from a recognised laboratory such as Micro Quality Labs, Summit Nutritional Laboratories or Eurofins?
  • Does the listing have fake reviews, to check enter the listing into its advanced algorithm will tell you high accuracy if its detecting fake reviews.
  • Check the supplement on and if its listed does it get a pass or fail.
  • Is the price overly cheap, NMN is an expensive supplement to produce if the supplement is overly cheap you can guarantee it either has no or very little NMN.
  • Does the company have good customer support and transparency practices, if you can reach out to the company for details such as COA and other details of their products, also do they have a verifiable address, business registration and contact phone number, if so its most likley you are dealing withi a legit company and therfore would more than likley be selling a pure product.

A list of brands supplement I trust and currently or have used include:

  • DoNotAge
  • ProHealth Longevity
  • Renew by Science
  • Tru Niagen
  • Doctors Best
  • California Gold
  • Life Extension
  • NOW Foods
  • GENEX Formulas
  • Double Wood
  • Jarrow
  • Swanson

I hope this post has been informative, please comment below Longevity supplements you are currenlty using and also let us know if there are any other checks you do when purchasing online to ensure you are purchasing legit products.

There is a company called Lifespan Supplements which gives the impression its linked to Prof Sinclair. Do you know anything about this company and whether the products are reliable?


Hi Caroline,

I have heard of them but have not used, they seem legitimate as they source their NMN from EffePharm/Uthever who are the largest and most respected producers of NMN. I have not seen any posts where they claim to be assocated with Dr Sinclair.

Would love your thoughts, please comment.x
