NMN (nicotinamide mononucleotide) supplements are popular for their purported anti-ageing benefits, yet there is insufficient human research to support these claims. While some biohackers, like Bryan Johnson, advocate for NMN to slow ageing, experts caution that more studies are needed. Quality control issues are prevalent, with many supplements not meeting label claims. NMN, converted to NAD in the body, is essential for cellular function and repair, but its efficacy in humans remains unproven. Alternative lifestyle changes, such as diet and exercise, are also recommended for longevity.
