What is NADH - and why haven't I heard of it?
You're not alone. Most people haven't. NADH is a natural coenzyme in every one of your cells. Its job is simple: turn the food you eat into usable energy (ATP) inside your mitochondria, your cellular power plants. Here's the catch, after 30 your NADH drops every year. Less NADH means less energy, focus, and recovery. It's been studied for decades, but it's fragile and hard to stabilize, which is why you've rarely heard of it. PureNADH delivers 100mg of stabilized NADH, the raw fuel your cells have been missing.
See the full 2-minute guide →How is this different from caffeine?
Caffeine borrows energy. You pay it back with a crash. PureNADH is different. It gives your cells the raw material to make their own energy, at the source. No spike. No crash. No jitters. You're not masking fatigue, you're restoring a natural process that fades with age. Most people still enjoy their morning coffee. They just stop needing 3 or 4 cups.
What if it doesn't work for me?
You're covered by our 100-day money-back guarantee. Don't feel a real difference in your energy, focus, or clarity? Contact us for a full refund. No return needed. We'd rather you try it risk-free than wonder "what if."
What are the ingredients?
One ingredient, done right: NADH, 100mg per capsule, at 99%+ purity. No caffeine. No stimulants. No fillers, colors, or preservatives. Each molecule is wrapped in a cyclodextrin shield that guards it from light and oxygen. The capsule is acid-resistant, so it survives your stomach and reaches your gut intact, where absorption actually happens.
Suggested use
Take 1 capsule each morning on an empty stomach, with a glass of water. Wait 15 to 20 minutes before eating for best absorption. Most people feel the first changes in 7 to 14 days. Full benefits build over 4 to 6 weeks as your reserves rebuild. Consistency is the key, your cells need steady fuel.
Who is it for?
Anyone 30 and up whose energy, focus, or recovery isn't what it used to be, especially if caffeine and other supplements haven't lasted. Busy professionals. Active adults who want steady energy without stimulants. If you'd rather own your energy than borrow it, this is for you.
This Is What Owned Energy Feels Like
Not a stimulant rush. This is what happens when your cells finally have the fuel they need.

Passed My Exams Because of This
I've been happily taking this for a while now. It helps me with concentration and memory. I started 3 months before my professional exams and passed, I think PureNADH was one of the reasons.

Why This Is the End of Borrowed Energy
You've tried the supplements. The stacks. The routines. None of them addressed the real problem, because they can't. NADH does. But it's extremely fragile: light, oxygen, and stomach acid destroy it. Most NADH supplements are dead before they reach your cells.
Patent-pending stabilization
NADH degrades within hours when exposed to light or oxygen. Our freeze-drying (lyophilization) process locks it in a stable state, keeping it potent for years, not hours. This is why most NADH supplements fail before you even open the bottle.
Survives your stomach
Your stomach acid destroys unprotected NADH on contact. Our cyclodextrin-shielded formula wraps each molecule in a protective ring structure, allowing it to pass through your digestive system intact and reach the cells that actually need it.
Full clinical dose
Most brands offer 5–20mg of unstabilized NADH. PureNADH delivers 100mg of 99%-pure NADH per capsule a full clinical dose that your cells can actually use. Every batch is independently lab-tested before it ships.
One capsule. That's it.
No stacking, no timing with meals, no complex protocols. One capsule in the morning on an empty stomach 30 minutes before eating. Most customers feel the difference within two weeks of daily use.

ATP Energy Production
Systematic Review · 2023
Primary electron carrier that directly fuels mitochondrial energy output.
A systematic review confirmed NADH's role as the essential coenzyme in cellular energy metabolism. It mediates multiple biological processes including energy production, mitochondrial function, and cell maintenance across all tissue types.
PubMed · Systematic Review · View study
Depression & Mood
Peer-Reviewed Research
Optimizes dopamine and serotonin production for mood regulation.
Research shows NADH supports the synthesis of key mood-regulating compounds while simultaneously enhancing brain energy metabolism. By providing the brain with adequate cellular fuel, NADH helps maintain stable neurotransmitter levels.
PubMed · Ying et al. · View study
DNA Repair & Cell Protection
Review · PMC
Supports DNA repair pathways and acts as a potent cellular antioxidant.
NADH neutralizes harmful free radicals, protecting cells from oxidative damage. It also plays a critical role in DNA repair through PARP proteins and sirtuin-mediated processes both essential for long-term cellular health.
PMC · Radenkovic et al. · View study
Immune System Function
Review · PMC · 2025
Immune cells require NADH to activate and maintain balanced response.
Research shows immune cells depend on NAD+ metabolism both to mount a response and to calm down once the threat is eliminated. Proper NAD+ levels help maintain a balanced immune system neither overactive nor sluggish.
PMC · 2025 Review · View study
Sleep Quality & Recovery
Frontiers in Aging · 2025
Improved sleep quality, duration, and reduced time to fall asleep.
Studies show NADH supports nighttime cellular repair and energy balance, contributing to better sleep architecture. Participants reported improved sleep quality and feeling more rested upon waking.
Frontiers in Aging
Aging & NAD+ Decline
Nature · 2025
NAD+ levels decline with age, directly linked to mitochondrial dysfunction.
Published in Nature, this review establishes that age-related NAD+ decline is a key driver of mitochondrial dysfunction, cellular aging, and disease. Supplementation with NADH is identified as a promising intervention strategy.
Nature · View study
Memory & Learning
Peer-Reviewed · ScienceDirect
Improved spatial memory and learning, especially in older subjects.
Subjects treated with NADH showed improved performance in memory tests. Notably, the benefits were most pronounced in older subjects suggesting NADH is particularly effective where age-related decline is greatest.
ScienceDirect · Rex et al. · View study
Physical Performance
Clinical Comparison
Supports sustained output and reduces post-exercise fatigue.
Research comparing NADH to conventional therapies found it supports mitochondrial efficiency during physical exertion. By directly fueling ATP production, NADH helps maintain energy and supports faster recovery.
ResearchGate · Alegre et al. · View study
Parkinson's Disease
Clinical Trial · Placebo-Controlled
Significant improvement in clinical symptoms via dopamine synthesis support.
In a trial of 15 PD patients receiving 10mg/day of NADH for four weeks, the NADH group showed significant clinical improvement. NADH supports dopamine synthesis the neurotransmitter most affected in Parkinson's disease.
