NMN, or nicotinamide mononucleotide, is trending on social media, with an Instagram search for #NMN revealing over 230,000 posts. This molecule, naturally produced in the body, is now being taken as a supplement by individuals seeking its purported anti-aging benefits. Celebrity biohacker Bryan Johnson is among those advocating for its use.
The obsession with staying young is widespread, as evidenced by over 40,000 results for “longevity” in Amazon’s books section. This fascination drives the global anti-aging market, valued at approximately $62 billion in 2021, with expectations to reach $93 billion by 2027. The NMN market alone is projected to be worth $1.19 billion by 2028.
While research into the effects of NMN supplements is ongoing, more studies are necessary to substantiate the claims made by manufacturers. In Hong Kong, NMN supplements are sold over the counter and online, provided they do not claim to treat diseases. In Australia, they are available only after a clinical consultation with a health practitioner.
Dr. Laurena Law, based in Hong Kong, notes that clients frequently inquire about the benefits of NMN supplements, including their potential to boost energy, improve mental function, enhance sleep, and alleviate menopause symptoms. However, she remains skeptical about NMN’s status as a longevity molecule, citing the lack of human data on its effects on biological aging.
Despite the uncertainties, NMN remains popular among biohackers like Johnson, who reportedly spends $2 million annually to slow his biological clock. Biotech and pharmaceutical companies have rapidly entered the NMN market, often with insufficient quality control. Tests on over a dozen NMN supplements in Singapore revealed that many products did not match their label claims. Some contained no NMN at all, while others had between 20% and 99.2% less than stated.
This issue of misleading labels is widespread in the supplement industry. One study found that 89% of supplement labels were inaccurate, and 12% of products contained ingredients banned by the US Food and Drug Administration (FDA). The FDA banned NMN as a dietary supplement in December 2022, not due to mislabeling but because the claims about its ability to treat, mitigate, or prevent diseases lacked scientific evidence.
The FDA states on its website, “A product sold as a dietary supplement and represented explicitly or implicitly for treatment, prevention, or cure of a specific disease or class of diseases meets the definition of a drug and is subject to regulation as a drug.”
As NMN continues to gain traction, consumers are advised to approach it with caution, keeping in mind the current limitations in scientific validation and regulatory oversight.
