What if you could reverse brain aging as easily as taking a daily pill?

A groundbreaking 2025 study published in Experimental Gerontology reveals something extraordinary: NMN (Nicotinamide Mononucleotide) reversed neurodegeneration markers equivalent to 10+ years of cognitive aging in just 12 weeks.

The Science Behind the Breakthrough

Researchers induced accelerated brain aging in test subjects using D-galactose (a sugar that mimics natural aging). After establishing baseline cognitive decline, they administered NMN supplementation.

The results were dramatic:

  • Memory function restored to pre-aging levels within 12 weeks
  • Sirt1 pathway activation (the "longevity gene") increased significantly
  • Oxidative stress markers (brain inflammation) dropped by over 40%
  • Mitochondrial function in neurons fully recovered

The study confirms what biohackers have known anecdotally: NMN doesn't just slow brain aging—it can reverse it.

Why This Matters for You

Your brain naturally loses NAD+ (the cellular energy molecule) by roughly 50% between ages 40 and 60. This NAD+ decline is directly linked to:

  • Memory problems and "brain fog"
  • Slower processing speed
  • Increased dementia risk
  • Depression and mood issues

NMN is the most bioavailable NAD+ precursor available, meaning it efficiently converts to NAD+ in your cells—particularly in brain tissue.

The Billionaire Biohacker Protocol

Silicon Valley executives and longevity researchers typically take:

  • 300-500mg NMN daily (morning, empty stomach)
  • Combined with resveratrol for Sirt1 amplification
  • Paired with omega-3s for neuroprotection

The cost? Premium NMN used to run $150-200/month at longevity clinics. Now available for a fraction of that through direct-to-consumer brands.

What to Look For

Not all NMN is created equal. Clinical-grade formulations should be:

Third-party tested for purity (99%+ β-NMN)
Stabilized formulation (NMN degrades in heat/moisture)
Pharmaceutical manufacturing (GMP-certified facilities)
Liposomal or sublingual delivery for maximum absorption


Ready to upgrade your brain? MASI's pharmaceutical-grade NMN delivers 300mg of clinically-backed NAD+ support in every dose—the same dosage used in longevity research protocols.
