Tru Niagen 300mg - NAD Supplement
After 40, your cells aren't as efficient as they used to be. Your recovery takes longer, your energy feels harder to sustain across a training block, and those back-to-back big days that used to be no problem now leave you digging deeper than you'd like. Here's what most athletes don't realize: a molecule called NAD+ — the master fuel regulator inside every one of your 37 trillion cells — naturally drops by up to 50% by middle age, and training stress accelerates that decline.
Tru Niagen is the most clinically studied NAD+ supplement available, using patented Niagen® nicotinamide riboside (NR) to rebuild what age and hard training take away.
Proven NAD+ Elevation — Not Just a Promise Tru Niagen's patented Niagen® ingredient is clinically proven to raise NAD+ levels by over 50% with a 300mg daily dose — and up to 150% with 1,000mg — verified in over 40 human clinical trials. No other NAD+ supplement comes close to that research depth.
Backed by the Most Credible Science in the Category Niagen® NR features in more than 65% of all registered clinical trials on nicotinamide riboside globally. It's the research-grade form used by world-leading scientists, endorsed by Nobel laureates, and trusted by elite performance directors like Mike Potenza of the San Jose Sharks. When researchers need results, this is what they reach for.
Tested Clean. Safe for Competitive Athletes. Tru Niagen is NSF Certified for Sport, meaning every batch is third-party tested for banned substances, potency, and purity. No artificial flavors or colors, no caffeine, no guesswork.
Nicotinamide riboside (NR) is a highly bioavailable form of vitamin B3 — meaning it slips directly through your cell walls and converts into NAD+ more efficiently than other precursors like NMN, niacin, or niacinamide. NAD+ is the coenzyme your mitochondria — the energy factories in your muscle cells — need to produce ATP. More NAD+ means better energy production, faster cellular repair after hard efforts, and improved resilience to the daily stressors of training, poor sleep, and life. Research also shows NR supports brain and heart cellular health, helping you stay sharp and durable over the long haul.
Daily Dose: Take one capsule (300mg) daily with or without food. Tru Niagen is designed for daily, consistent use — cellular benefits compound over time. Scale to 1,000mg daily if you're a master athlete or dealing with high training stress.
Timing: Morning works best for most athletes, paired with your other daily supplements. Results aren't overnight — most people notice improved energy consistency and recovery quality within 2–4 weeks of daily use.
Pro Tip: Stack Tru Niagen with Quicksilver Scientific NAD+ Gold (sublingual NMN) for a dual-pathway NAD+ protocol — the approach Matt personally uses during heavy training blocks.
Elite sports performance directors, masters athletes, and longevity-focused endurance competitors rely on Tru Niagen as their foundational cellular health supplement. Whoop and Oura users consistently report more consistent HRV and recovery scores after 4–6 weeks of daily use.
This isn't just another longevity supplement collecting dust in your cabinet. This is the clinically validated cellular foundation that keeps your engine running as hard as your training demands.
