Developed in the lab that defined NAD+ research
What is NAD+ and why is it important?
Nicotinamide adenine dinucleotide (NAD) is the energy currency of your cells. It powers everything from muscle movement to brain function.
Your body makes NAD+ naturally. But production slows down with age.
This creates a cellular energy problem. Your cells can’t repair themselves properly. Energy production drops.
The result? You feel older than you should.
Restoring NAD+ levels helps your cells function like they did when you were younger.
Results backed by clinical research
Clinical studies show our formula works fast.
26 people between ages 35-65 took our NAD+ Booster daily. Within 4 weeks, most participants doubled their NAD+ levels.
85% reached the optimal range. The average boost was 100% higher than baseline.
We tracked progress using advanced Intracellular NAD® testing. This measures NAD+ inside your actual cells, where it actually works.
This chart shows the steady progress participants experienced week by week.
Fig. 1 – Clinical Trial Data: 26 volunteers aged 35–65 took 2000mg of Jinfiniti Vitality Boost daily. Intracellular NAD levels were measured at two baseline points and 2 and 4 weeks post-supplementation. At 4 weeks, 22 of 26 (85%) participants had optimized NAD levels. Two others were near optimal with a slight dosage increase, while one showed modest improvement, and another showed no change. On average, NAD levels doubled.
Fig. 2: Real data from clinical use. 22 patients in Dr. Richard Delany’ office, aged 45 -94 years old with various health issues, were supplemented daily with 2000mg (2 scoops) of Accuri® Vitality Boost. Dosage was adjusted after retesting if NAD levels were not optimized. 80% of patients had their NAD optimized, some need higher dosage. Significant clinical improvement observed in most patients.
Fig. 3: Real Data from a Functional Medicine Clinic that uses Pure Precursor from another brand. 12 patients had before and after supplementation NAD levels measured with the Jinfiniti NAD test. NAD levels were elevated by pure precursor in all but one patients. However, no patient had optimized NAD levels (>40μM). Vitality Boost works much better in these same patients.
Real results from clinical trials
Clinical studies prove our formula works faster and better than single ingredients.
The science: Four ingredients work together through different pathways. This multi-pathway approach beats single NAD+ precursors every time.
The proof:
- 85% success rate in clinical trials (Figure 1)
- Validated in hundreds of medical practices (Figure 2)
- 3x more effective than standalone NAD+ supplements (Figure 3)
Real benefits: Users experience noticeable improvements in energy, sleep, and cognitive function within weeks.
Verified results: We use precise NAD+ testing to track your progress and provide personalized guidance for optimal outcomes.
What makes our NAD+ supplement formula unique?
Most NAD+ supplements only give you one ingredient. We give you four that work together.
Our formula includes the most direct NAD+ precursor. But we don’t stop there.
We add D-ribose to fuel your body’s natural NAD+ recycling system. Creatine supports cellular energy production. Niacinamide helps maintain steady NAD+ levels.
Each ingredient targets NAD+ production differently. Together, they create better results than any single compound alone.

NAD Booster vs. NAD Therapy
Most people think IV therapy is the gold standard for NAD+. Clinical data tells a different story.
Vitality NAD+ Booster users reached optimal NAD+ levels in just 4 weeks. That’s faster than many IV protocols and way more convenient.
Almost all NAD+ research available uses oral precursors, not expensive IV treatments.
No clinic visits. No high per-session costs.
You get better results at home for a fraction of the price.
NAD Booster results compared to NAD therapies
Our clinical data shows oral supplementation beats IV and injection therapies.
Why IV therapy falls short: The NAD+ molecule is too large to enter cells directly. It breaks down quickly in your bloodstream before cells can use it.
Injection limitations: SubQ shots work slightly better than IV but still don’t reach optimal levels. Plus they’re expensive and inconvenient.
Our advantage: We give your cells the building blocks to make NAD+ naturally. This works with your body’s processes instead of against them.
The result: Better NAD+ levels in 4 weeks, at home, for a fraction of the cost. (Figure 1)

From 30 RPM to more like 50 RPM.
I've been taking the supplement for 2 weeks and already notice that I'm thinking differently. I'm not struggling for words as much and it's easier to remember things. I'm moving faster...instead of going at 30 RPM, now it's more like 50 RPM.
