Live Longer NMN+ is built around one insight: aging is primarily a cellular energy crisis. As NAD+ levels drop with age (by roughly half between 40 and 60), mitochondria produce less energy, DNA repair slows, and cellular function degrades. NMN+ directly addresses this with four ingredients that each target a different aspect of the same problem — NMN raises NAD+, Urolithin A clears damaged mitochondria, TMG supports the methylation processes NMN depletes, and Ca-AKG improves metabolic efficiency at the cellular level. This is the only formula that stacks all four in clinically validated doses.
Sleep Better is Longevity Method's most accessible product — targeting the most universal problem for adults over 35: sleep quality deteriorating with age and work stress. Poor sleep accelerates every marker of cellular aging, which makes Sleep Better not just a comfort product but a genuine longevity intervention. The formula targets the three main barriers to restorative sleep: inability to switch off mentally, shallow or broken sleep cycles, and stress-elevated cortisol that prevents deep sleep. Unlike melatonin alone (which only helps you fall asleep), Sleep Better is designed for sleep architecture — the quality of sleep, not just the quantity.
Play Harder bridges longevity science and men's performance health. By 40, most men experience measurable declines in testosterone, prostate health markers shift, and post-workout recovery slows. Play Harder addresses all three simultaneously — men's hormonal support, prostate maintenance, endurance capacity, and recovery speed. Unlike generic testosterone boosters with inflated marketing claims, this formula sits within Longevity Method's science-first approach — targeted, evidence-informed, and dosed to actually work. Pairs with NMN+ as a complete men's longevity stack.
Keep Balanced is Longevity Method's women's formula, targeting the specific hormonal shifts women experience from perimenopause onwards — declining oestrogen, mood volatility, stress sensitivity, irregular cycles, and the energy disruption that comes with hormonal change. Unlike general women's supplements that simply add iron and call it "for her," Keep Balanced is designed around the actual mechanisms of hormonal aging in women, with ingredients targeting both the symptoms (stress, mood, sleep) and the underlying hormonal environment.
Live Longer Booster is Longevity Method's most advanced product — designed as a companion to NMN+ for users who want to target a second pillar of cellular aging: DNA damage accumulation. While NMN+ focuses on energy production (NAD+) and mitochondrial health (Urolithin A), Booster targets DNA repair pathways and cellular renewal. This is the product for users who have already established an NMN routine and want to extend their longevity stack. Not recommended as a first product — start with NMN+, add Booster after 30 days.
