  • Six clinically studied bioactives: Niagen® nicotinamide riboside (500mg), NAC (600mg), Betaine (600mg), PureQQ® (20mg), Vitamin C (200mg), plus B-vitamins — every ingredient dosed to research-validated levels.
  • Boosts NAD+ levels: Niagen® is a clinically studied nicotinamide riboside that raises cellular NAD+ — the coenzyme essential for mitochondrial energy production and DNA repair.
  • Mitochondrial biogenesis: PureQQ® (pyrroloquinoline quinone) promotes the growth of new mitochondria — the cellular energy generators that decline with age.
  • Antioxidant defense: NAC and Vitamin C support glutathione production and neutralize oxidative stress from exercise, environment, and aging.
  • DNA repair and methylation: Betaine, folate, and B12 supply methyl groups critical for DNA repair processes and balanced cellular function.
  • NSF Certified for Sport®: Independently tested. Vegan, GMO-free. Take 3 capsules daily in the morning or early afternoon.

Momentous Longevity is a daily cellular health formula combining six clinically studied bioactives — Niagen® nicotinamide riboside, NAC, Betaine, PureQQ®, Vitamin C, and B-vitamins — designed to support the core pillars of healthy aging: NAD+ production, mitochondrial function, antioxidant defense, DNA repair, and methylation.

Rather than focusing on a single hallmark of aging, Longevity addresses multiple pathways simultaneously. Each ingredient amplifies the others, creating synergistic support across all five pillars of cellular health.

Key actives per 3-capsule serving:
• Niagen® Nicotinamide Riboside (500mg) — boosts NAD+ levels for mitochondrial energy and DNA repair
• NAC (600mg) — supports glutathione production and antioxidant defense
• Betaine Anhydrous (600mg) — supplies methyl groups for DNA repair and cellular function
• PureQQ® (20mg) — supports mitochondrial biogenesis and cognitive function
• Vitamin C (200mg) — antioxidant defense and cellular integrity
• B-Vitamins (B3 Niacin, B9 Folate, B12) — metabolism, energy regulation, methylation

What it does:
• Metabolic support and energy production
• Antioxidant defense and stress resilience
• DNA repair and protection
• System balance through methylation support
• Cognitive support and brain health

Who benefits:
• Adults over 35 supporting healthy aging
• High-performers wanting comprehensive cellular health support
• Athletes seeking recovery and mitochondrial support
• Anyone consolidating multiple aging-related supplements into one daily protocol

Take 3 capsules daily in the morning or early afternoon. Each jar contains 30 servings (90 capsules).

What does Longevity do?

Longevity combines six clinically studied ingredients that support cellular health — NAD+ levels (Niagen®), mitochondrial biogenesis (PureQQ®), antioxidant defense (NAC, Vitamin C), DNA repair and methylation (Betaine, B-vitamins). It's a comprehensive daily formula for healthy aging.

Why is Niagen® the foundation?

Niagen® is a patented, clinically studied form of nicotinamide riboside that effectively raises NAD+ levels. NAD+ is critical for cellular energy and DNA repair but declines with age. NMN — another NAD+ precursor — is no longer legally available as a supplement in the U.S., so Niagen® is the most studied option.

Can I take this with other Momentous supplements?

Yes. Longevity is designed to complement protein, creatine, omega-3, and other foundational supplements. It addresses cellular-level health that other products don't target.

When should I take it?

Take 3 capsules in the morning or early afternoon. Some of the B-vitamins can be energizing, so taking it later may interfere with sleep.

Is it third-party tested?

Yes. Every batch is NSF Certified for Sport® — independently tested for purity, label accuracy, and banned substances. Vegan and non-GMO.
