The Experience
What You'll Feel
Week 1
NAD⁺ Loading
NAD+, quercetin, and resveratrol begin accumulating in tissue. No dramatic effects yet — this is the absorption phase as cellular NAD⁺ levels rebuild and SIRT1 activation begins.
Week 2
Energy Shifts
Mitochondrial energy pathways are becoming more efficient. Some notice subtle improvements in how sustained their energy feels — particularly in the afternoon when NAD⁺-dependent processes are most active.
Week 3
Clarity & Focus
Many report reduced afternoon slumps and sharper mental clarity. NAD⁺ levels are now meaningfully elevated throughout major tissue types, and cerebrovascular function is improving.
Week 4
Fatigue Easing
Physical and mental fatigue begin to ease noticeably. Quercetin's senolytic activity is reducing the background inflammatory load — the body feels less worn down after exertion.
Week 6
Antioxidant Set
Energy is more consistent throughout the day. Resveratrol's antioxidant protection is now fully established at the cellular level — oxidative stress is declining and recovery is meaningfully faster.
Week 8
Longevity Build
The compound effects consolidate. Cellular repair, cognitive function, and cardiovascular support are all operating at a higher baseline — the three compounds are now working in full synergy.
Week 12+
Your Longevity Floor
Full NAD⁺ support, sirtuin activation, and antioxidant protection are now part of your daily baseline. Keep supplementing — the longevity benefits of all three compounds compound over years.
The Formula
Why Our Longevity+
Most longevity blends use synthetic trans-resveratrol in isolation — and studies have measured oral bioavailability at less than 1% in this form, because CYP enzyme first-pass metabolism in the gut and liver degrades almost all of it before it reaches circulation. Stripping resveratrol from its plant source removes the polyphenol co-factors that modulate that rapid breakdown.
Ours uses whole-plant Japanese Knotweed extract standardised to 98% trans-resveratrol, alongside NAD+ directly and Quercetin — a SIRT1 activator and CD38 inhibitor that prevents NAD+ degradation — rather than a single compound working in isolation.
The Science
Evidence-Based Formulation
Every ingredient in Longevity+ is selected based on peer-reviewed clinical research — NAD+ precursors, senolytic compounds and sirtuin activators at effective doses, supporting cellular health and healthy ageing.
01
NAD+ Repletion Improves Mitochondrial and Stem Cell Function
Research found that restoring NAD+ levels in aged mice significantly improved mitochondrial function and enhanced muscle stem cell activity, promoting tissue regeneration. NAD+ repletion reversed age-associated decline in stem cell function, supporting NAD+ precursor supplementation for cellular health in ageing.

Quercetin as a Senolytic Drug: Clearing Senescent Cells to Combat Age-Related Decline
A landmark study found quercetin combined with dasatinib functions as a senolytic — selectively eliminating senescent cells that accumulate with age and drive chronic inflammation and tissue dysfunction. In aged mice, treatment reduced senescent cell burden and improved physical function and healthy lifespan.

NAD+ Metabolism and Aging Mechanisms
Research confirmed NAD+ participates in hundreds of enzymatic reactions central to energy production and DNA repair, with levels declining by up to 50% between young adulthood and old age. This decline directly impairs mitochondrial efficiency and cellular repair capacity, making NAD+ restoration a rational anti-ageing strategy.

Resveratrol and Bone and Metabolic Health
Clinical research found resveratrol supplementation significantly improved bone mineral density and metabolic markers in postmenopausal women, with improvements in glycaemic control and insulin sensitivity. Resveratrol's SIRT1 activation and NF-κB inhibition link these benefits to longevity-associated signalling pathways.

Resveratrol Improves Brain Function and Neuroprotection
A double-blind RCT found resveratrol supplementation improved cognitive performance and significantly increased cerebrovascular blood flow in postmenopausal women versus placebo. Resveratrol's SIRT1 activation and improved cerebral perfusion support brain health as a central component of healthy ageing.

Resveratrol and Sirtuin Activation in Aging
Research confirmed resveratrol activates SIRT1 and SIRT3 deacetylases — proteins activated by caloric restriction and linked to extended lifespan in multiple organisms. Sirtuin activation improves mitochondrial biogenesis, reduces oxidative stress, and promotes DNA repair mechanisms underlying resveratrol's longevity effects.

Usage
How to Take It
01
2 Capsules Daily in the Morning
Take 2 capsules every morning with food. NAD+ precursors align best with the body's circadian NAD+ rhythm when taken in the morning. Fat-soluble compounds in the formula absorb better with a meal.
02
Take with Food
This formula contains fat-soluble compounds that absorb most effectively with a meal containing healthy fats. A breakfast with avocado, eggs, or olive oil supports peak absorption across all three ingredients.
03
Stay Consistent for 8–12 Weeks
Benefits for energy, cognitive clarity and cellular health build progressively over 8–12 weeks of consistent supplementation. NAD+ restoration and sirtuin activation are cumulative — give your body the time it needs.

I've been following the longevity science for years and this formula is impressively well-researched. The 98% resveratrol standardisation and the quercetin as a CD38 inhibitor alongside the NAD+ shows someone actually read the literature before formulating.
The quercetin as a senolytic alongside the NAD+ is an important combination most longevity products miss. Every ingredient choice here shows real understanding of the science. Energy and vitality are both noticeably better.
Good product and comprehensive formula. Longevity supplements work on a long time horizon — I'm judging this on a three-month window and the improvements to energy and sleep quality are clear and consistent.
Eight weeks in and sleep quality, morning energy, and general resilience have all improved. The kind of product that makes a difference over years — I'm committed to this for the long run.
Stacked this with NMN and the synergy is obvious. Sustained energy, faster recovery, sharper focus. The combination of NAD+ and sirtuin activation makes physiological sense.
At my age — mid-sixties — energy and vitality have become priorities. This is the most research-backed longevity formula I've found and after three months the difference is real and measurable.
Really excellent value for the quality of ingredients included. Nothing underdosed, no fillers, and every compound has a clear research rationale. A daily essential I won't be dropping.
