    Science

    The need to know

    Interesting facts

    Ageing isn't just the passage of time; it's the culmination of damage at a cellular and molecular level, and we now have the means to address this.

    Sirtuins, proteins that regulate cellular health, were first discovered in yeast but have since been identified as major players in human longevity.

    AMPK, often dubbed the "master metabolic switch", orchestrates energy balance in our cells, and its activation can mimic the benefits of calorie restriction, a known longevity enhancer.

    What are the benefits?

    This is the stack Dr Geoff Mullan takes himself. That matters because most supplement founders do not actually use their own products at the doses they sell. This one was built around what he wanted for his own longevity protocol, then made available to patients, then to everyone.

    The formulation targets three cellular processes that longevity researchers now consider the most consequential for how the body ages. First, mitochondrial energy production. Your mitochondria generate the ATP that powers every cell in your body. When they decline, everything declines with them. CoQ10 supports the electron transport chain directly. NMN raises NAD+ levels, which mitochondria depend on to function. These two ingredients working together are more effective than either one alone.

    Second, autophagy. This is the body's recycling system. It breaks down damaged organelles, misfolded proteins and cellular debris, then repurposes the raw materials. Spermidine is one of very few compounds shown in human research to meaningfully support autophagic activity. Urolithin A targets a related but distinct process called mitophagy, which is the selective removal of damaged mitochondria specifically. Most longevity stacks include one or the other. This includes both.

    Third, sirtuin activation. Sirtuins are a family of proteins that regulate DNA repair, inflammatory response and metabolic efficiency. Trans-resveratrol activates them. But sirtuins cannot function without adequate NAD+, which is why the NMN in this formulation is not just an energy ingredient. It is also the cofactor that makes sirtuin activation possible.

    Vitamins D3 and K2 are included as a pair for bone metabolism, immune regulation and calcium distribution. Methylated B vitamins support the methylation cycles that affect neurotransmitter production, detoxification and gene expression.

    Eight compounds. Each one selected for a specific mechanism. No overlap, no filler, no ingredients included because they look good on a label. This is the most comprehensive daily longevity protocol we offer.

    Clinically studied doses. Pharmaceutical-grade raw materials. Third-party tested.

    The science

    NMN. The humanpeople NMN is 99.5% pure B-nicotinamide mononucleotide (“NMN”), which is highly absorbable in the gut. It increases energy production and activates sirtuins. It increases AMPK and enhances cell energy production.

    Urolithin A: Metabolite that improves mitochondrial function by inducing mitophagy, the removal of damaged mitochondria.

    Spermidine: Induces autophagy, a cellular recycling process that removes damaged components, enhancing cellular function and longevity.

    Resveratrol (trans form) works by activating sirtuin pathways. Trans-resveratrol is the most active form and works synergistically with NMN. It also increases NAD+ levels by activating the NMNAT1 enzyme up to 5-fold in neurons.

    Coenzyme Q10 is a commonly used cofactor because it is essential as a mitochondrial electron transporter and acting as an antioxidant. It delays brain atrophy, and a blinded study showed that within 8 days, the participants on CoQ10 were able to cycle further with lower fatigue.

    B vitamins: Synthesis of CoQ10 is dependent on vitamins B2 (riboflavin) and vitamins B6 (pyridoxal-phosphate), folate (vitamin B9), pantothenic acid (vitamin B5), niacin (vitamin B3) and vitamin C.

    Vitamins D3, K2, and Methylated B Complex: These vital nutrients offer holistic support, from bone health to metabolic processes and cellular energy synthesis.

    I’ve always been lucky with my skin, but out of the blue last year I started getting a stubborn blemish that just wouldn’t go away... turns out it was hormonal! After feeling totally frustrated, I found humanpeople and honestly, it’s been such a game-changer.
