Product Description
You've dialed in your training, your fueling, your sleep. But somewhere past your mid-30s, recovery starts taking longer, focus gets harder to hold onto during long blocks, and the energy you used to count on just isn't as reliable. Here's what most athletes don't realize: that shift often starts at the cellular level, with declining NAD+, the coenzyme every cell needs to produce energy and repair itself.
Momentous Longevity is a daily formula built around six clinically-studied ingredients that target cellular health from every angle, not just NAD+.
Six Ingredients Working Together, Not One Doing All the Work Most NAD+ boosters lean on a single ingredient and stop there. Longevity pairs Niagen® with five more clinically-studied compounds that cover energy production, antioxidant defense, and DNA repair, the fuller picture of what keeps your cells running well.
Built for the Long Game, Not Just Race Day This isn't a pre-workout or a recovery shake. It's a daily formula designed to protect the machinery: mitochondria, DNA, brain cells, that determine how well you'll be training in 10 or 20 years.
NSF Certified for Sport Every batch is independently tested for banned substances, so you always know what's going into your body.
Niagen® is a clinically-studied form of vitamin B3 that raises your NAD+ levels, the coenzyme that powers how efficiently your mitochondria make energy and how well your DNA repairs itself after the damage hard training creates. NAC and vitamin C work together to boost glutathione, your body's master antioxidant, protecting your cells from the oxidative stress that builds during heavy training blocks. PQQ supports the growth of new mitochondria, the power plants inside your cells that turn fuel into usable energy, while also shielding them from that same oxidative damage. Betaine, folate, and B12 supply the methyl groups your cells need for a process called methylation, essentially the switchboard that keeps DNA repair, detox, and energy regulation running in balance. That same NAD+ and B-vitamin support also fuels your neurons, which is why athletes reach for Longevity for mental clarity under sleep-deprived, high-stress training loads, not just physical recovery.
Daily Use: Take 3 capsules once daily in the morning or early afternoon, when your energy demand is highest.
Stay Consistent: Take it at the same time every day. Cellular benefits build over weeks, not days.
Pro Tip: Give it 4–6 weeks before you look for changes in focus and energy, and 12+ weeks for the full cellular benefits to show up.
Athletes who train hard enough, and long enough, to know recovery and mental clarity aren't guaranteed forever have made Longevity part of their daily routine, with many reporting sharper focus and faster recovery within weeks.
This isn't just another NAD+ booster. This is cellular health built for athletes who plan on training for decades, not just seasons.

Momentous Longevity FAQ's
Everything you need to know about Momentous Longevity.



Take 3 capsules once daily, ideally in the morning or early afternoon when your body's energy demand is highest. It can be taken with or without food.
NAD+ is a coenzyme every cell needs to produce energy and repair itself. Training hard depletes it faster, and low NAD+ shows up as slower recovery, foggier focus, and less reliable energy over time.
Niagen® is a patented, clinically-studied form of nicotinamide riboside (vitamin B3) shown to raise NAD+ levels. Unlike single-ingredient NAD+ products, Longevity pairs it with five more clinically-studied ingredients that support the antioxidant, DNA repair, and mitochondrial pathways NAD+ depends on.
Most athletes notice sharper focus and energy within 4–6 weeks of daily use. Full cellular benefits build over 12+ weeks and continue with ongoing daily use.
Yes. Longevity is designed to stack into a daily routine alongside creatine, protein, and other foundational supplements without overlap.
