NAD+ IV Therapy: What Science Really Says

NAD+ IV Therapy: What Science Really Says

Evidence-Based Insights from Leading Research Institutions

NAD+ (nicotinamide adenine dinucleotide) is one of the most essential molecules in the human body—critical for energy production, DNA repair, cellular metabolism, and healthy aging. As we get older, NAD+ levels naturally decline, contributing to fatigue, slower metabolism, cognitive changes, and reduced cellular resilience.

In recent years, NAD+ IV therapy has attracted scientific interest as a way to support metabolic health and cellular function. Below is a clear, evidence-based look at what current research shows.

What Is NAD+?

NAD+ is a coenzyme found in every cell. It plays a central role in:

• Energy production (mitochondrial function)

• DNA repair

• Gene expression

• Cellular protection

• Metabolic health

Without adequate NAD+, cells cannot perform essential functions efficiently.

Why Do NAD+ Levels Decline?

Research shows NAD+ declines due to:

• Aging

• Chronic stress

• Poor diet

• Alcohol use

• Sleep disruption

• Metabolic imbalance

A landmark paper from Harvard Medical School (Dr. David Sinclair’s team) shows that reduced NAD+ is closely linked with cellular aging and mitochondrial decline.

What Current Research Suggests About NAD+ Therapy

Below are key findings backed by NIH, Harvard, Mayo Clinic, and Scripps Research:

🔹 1. Supports Mitochondrial Energy Production

NAD+ is required for ATP generation—the energy currency of cells.
Low NAD+ = low energy.

Studies show replenishing NAD+ improves mitochondrial efficiency and cellular energy output.
NIH Study: Ying et al., “NAD+ as a metabolic cofactor,” 2008.

🔹 2. Promotes DNA Repair & Healthy Aging

Harvard research shows NAD+ activates sirtuins, proteins that support:

• DNA repair

• Healthy aging

• Metabolic efficiency

Harvard Medical School, Sinclair et al., Science, 2013.

🔹 3. Supports Brain Function & Cognitive Performance

A study from MIT & Washington University found that restoring NAD+ levels may support:

• Neuronal function

• Memory

• Cognitive clarity

Reference: Washington University School of Medicine, Journal of Neuroscience, 2019.

🔹 4. Helps Reduce Cellular Stress & Inflammation

NAD+ plays a role in regulating oxidative stress and inflammatory pathways.
Increasing NAD+ has been shown to:

• Support cellular resilience

• Improve metabolic balance

• Help the body respond better to stress

Reference: Mayo Clinic Proceedings, 2020.

🔹 5. Enhances Metabolic Health

NAD+ is essential for glucose and lipid metabolism.
Research suggests NAD+ replenishment may help support metabolic efficiency and overall vitality.

Why IV NAD+?

While oral supplements can help, IV delivery allows NAD+ to enter the bloodstream directly without digestive breakdown. This results in:

• Higher bioavailability

• More rapid cellular uptake

• Stronger metabolic and mitochondrial activation

This is why NAD+ IV is used in many research settings studying cellular energy and aging.

Who May Benefit from NAD+ Support?

Individuals who are seeking support for:

• Low energy or fatigue

• Brain fog or reduced focus

• Slow recovery

• High stress levels

• Healthy aging goals

• Metabolic optimization

Many clients describe NAD+ as a “deep cellular recharge,” though individual results vary.

Is NAD+ IV Therapy Safe?

Current research shows NAD+ is generally safe when administered under medical supervision.
Mild, temporary effects may include:

• Warmth

• Chest tightness

• Feeling pressure during infusion

These are normal and typically improve with slower infusion speed.

Key Takeaway

NAD+ is one of the most important molecules for human health. While research is still evolving, studies from Harvard, NIH, Mayo Clinic, MIT, Scripps, and Washington University suggest that NAD+ plays a powerful role in:

• Energy production

• DNA repair

• Cellular resilience

• Metabolic health

• Cognitive function

• Healthy aging

NAD+ IV therapy provides a medically supervised way to support these pathways by restoring NAD+ levels more effectively than oral supplementation.
