Why Britain’s Leading Biohackers are Moving Beyond NMN
NMN has long been the undisputed king of longevity. We all took it to boost NAD+ and "fuel" our sirtuins. But as the science of Medicine 3.0 evolves, a new heavyweight has emerged from the ocean; one that doesn't just provide the fuel, but actually starts the engine.
Meet Fucoidan: The potent SIRT6 activator that’s making NAD+ precursors look like half the story.

Regulatory "Novel Food" Limbo
The shift toward Fucoidan is being accelerated by the ongoing regulatory uncertainty surrounding NMN in Great Britain. As of 2024/2025, the UK Food Standards Agency (FSA) has maintained that NMN is classified as a 'Novel Food,' meaning it lacks the pre-market authorisation required for legal sale as a food supplement. This has left the UK market in a state of 'regulatory limbo,' causing major retailers like Amazon to delist products and leaving many high-end suppliers struggling to guarantee consistent, legal supply. In contrast, Prime Ageing’s Fucoidan (a naturally occurring polysaccharide extracted from brown seaweed) is fully compliant with UK food safety standards. For the serious biohacker, this offers a dual advantage: you get a more potent SIRT6 activator and the long-term 'regulatory peace of mind' that your longevity protocol won't be interrupted by sudden UK border seizures or retail bans.
Three Reasons to add Fucoidan to your daily supplements:
1. Direct SIRT6 Activation (The "Longevity Protein")
While NMN provides the NAD+ that sirtuins need to function, Fucoidan directly activates SIRT6 self-ribosylation. In recent 2025 trials, Fucoidan was the only natural compound shown to effectively "wake up" this master regulator of genomic stability.
2. It Clears What NMN Leaves Behind
NMN supports healthy cells, but it does nothing for "Zombie Cells" (senescent cells). Fucoidan is a natural senotherapeutic. It identifies and helps clear senescent cells in the kidneys and lungs while suppressing the toxic inflammatory signals (SASP) that cause "inflammaging."
3. Reversing the Genetic Clock
In a breakthrough 2025 pre-print, oral Fucoidan didn't just slow ageing - it reversed biological age as measured by epigenetic clocks. While NMN helps maintain energy, Fucoidan is rewriting the underlying code of cellular decline.
