Essential Information Before Taking NAD+ Booster
What is NAD+ and why is it important?
What is NAD+ and why is it important?
Nicotinamide adenine dinucleotide (NAD+) is a crucial coenzyme involved in various cellular processes, including energy metabolism, DNA repair, and cell signaling. It is essential for maintaining cellular health and function, and its levels decline with age, contributing to age-related diseases.
Importance of NAD+
- Energy Metabolism: NAD+ is vital for redox reactions, facilitating energy production through glycolysis and mitochondrial respiration, which are essential for cell growth and survival.
- DNA Repair and Gene Regulation: It acts as a co-substrate for enzymes like sirtuins and PARPs, which are involved in DNA repair and gene expression regulation.
- Neuroprotection: NAD+ supports neuronal function and resilience against stress, playing a role in synaptic plasticity and protection against neurodegenerative diseases such as Alzheimer’s and Parkinson’s.
- Aging and Disease: Declining NAD+ levels are linked to aging and various diseases, including cancer, metabolic disorders, and neurodegeneration. Restoring NAD+ levels is being explored as a therapeutic strategy to mitigate these conditions.

How does NAD+ Booster increase NAD+ levels?

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.
Is Vitality ↑® NAD+ Booster clinically validated?
Our patent-pending formulation combines the most effective NAD precursor with three synergistic ingredients: creatine monohydrate, D-ribose, and niacinamide. This precise combination maximizes cellular NAD production through multiple pathways, setting it apart from single-ingredient NAD supplements.
As demonstrated in our clinical studies (Figure 1), Vitality ↑® NAD+ Booster achieves superior NAD elevation compared to standalone precursors. This effectiveness has been further validated across hundreds of medical clinics (Figure 2) and through documented results from thousands of users, with consistent NAD optimization in approximately 85% of cases. Figure 3 clearly illustrates how our formulation outperforms pure NAD precursors from other manufacturers.
The real-world impact is clear: users with optimized NAD levels report significant improvements in energy, sleep quality, and cognitive function. Our commitment to measurable results means we verify supplement effectiveness through our Intracellular NAD® Test, allowing us to track actual improvements in cellular NAD levels.
For every customer, we provide individualized support to optimize results and back our product with a satisfaction guarantee focused on achieving improved NAD levels.

What makes our NAD+ supplement formula unique?
Our formula combines creatine and D-ribose with NAD precursors to enhance cellular energy production. D-ribose boosts NAD+ synthesis through the salvage pathway, while creatine supports ATP production, creating a comprehensive solution to raising NAD+ levels.
What makes our NAD+ supplement formula unique?
While many supplements contain a single NAD precursor, our Vitality NAD+ Booster takes a comprehensive approach to cellular energy optimization by including three additional strategic ingredients that work synergistically to enhance NAD metabolism:
- Niacinamide supports your body’s natural NAD recycling pathways, helping cells maintain healthy NAD levels more efficiently while regulating key longevity-promoting proteins called sirtuins
- D-ribose provides the essential building blocks needed for NAD synthesis and ATP production, ensuring your cells have the raw materials needed to maintain optimal energy levels
- Creatine acts as a cellular energy buffer, maintaining consistent ATP availability that supports efficient NAD production and utilization, particularly in high-energy-demand tissues like muscles and brain
This scientifically-validated combination creates a more effective NAD optimization strategy than single-ingredient formulations, reflecting our commitment to addressing cellular energy production comprehensively.

How does NAD+ Booster compare to conventional NAD therapies?
How does NAD+ Booster compare to conventional NAD therapies?
Our clinical data reveals that Vitality NAD+ Booster outperforms both intravenous (IV) and subcutaneous (SubQ) NAD+ therapies in raising cellular NAD levels. This finding challenges the common assumption that direct NAD+ administration through injection or infusion is the most effective approach.
While IV NAD+ therapy has its place in specific medical treatments, it faces several biological hurdles for general NAD optimization. The NAD+ molecule itself is too large to enter cells directly, and it breaks down rapidly in the bloodstream. Our research shows that IV NAD+ infusions rarely elevate NAD levels above baseline, despite their higher cost and more invasive nature.
SubQ NAD+ injections show slightly better results but still fall short of optimal levels. As demonstrated in Figure 1, users of SubQ NAD+ consistently maintained suboptimal NAD levels (pink bars). In contrast, the same individuals achieved optimal NAD levels within just 4 weeks after switching to our Vitality NAD+ Booster (blue bars).
By providing your cells with the precise building blocks they need to produce NAD+ naturally, Vitality NAD+ Booster offers a more efficient, convenient, and cost-effective path to optimal NAD levels. This approach aligns with your body’s natural processes while avoiding the drawbacks of invasive therapies.
