NAD+

NAD+ (Nicotinamide Adenine Dinucleotide) is a vital coenzyme found in every cell of the body. It plays a major role in energy production, cellular repair, and healthy aging. NAD+ levels naturally decline with age, which is why it's being widely studied for its potential to boost energy, brain function, and metabolic health.

NAD⁺ and its precursors (like NMN and NR) are currently being researched for a variety of uses. These compounds are not FDA-approved for treatment or diagnosis of any disease. All content is for educational purposes only.

What is NAD+?

NAD⁺ is a naturally occurring coenzyme found in every cell of the body. It plays a critical role in metabolic function, energy production, DNA repair, and cellular resilience. Because NAD⁺ levels decline with age, researchers have become increasingly focused on how boosting NAD⁺ — either directly or through precursors like NMN or NR — could support healthy aging, weight loss, cognition, and metabolic health.

Potential Benefits Shown in Studies

Boosting energy and mitochondrial function
Supporting cellular repair and DNA maintenance
Improving brain clarity and cognitive performance
Enhancing muscle recovery and endurance
Promoting healthy aging and longevity
Aiding metabolic function and fat breakdown
Protecting against oxidative stress and inflammation

Mechanisms of Action

NAD⁺ is essential to several key biological systems:

Energy Metabolism: Acts as a coenzyme in redox reactions, helping mitochondria generate ATP.
DNA Repair: Fuels enzymes like PARPs that repair cellular damage caused by oxidative stress and aging.
Gene Regulation: Activates sirtuins (especially SIRT1), which influence inflammation, fat storage, and longevity.
Neuroprotection: In preclinical studies, NAD⁺ supports brain health and protects neurons from degeneration.

Research Highlights

Weight Loss & Metabolism

A Harvard-backed clinical study found that overweight adults who supplemented with NMN (a precursor to NAD⁺) for 28 days experienced:

Significant weight loss
Lower cholesterol levels
Reduced blood pressure

These results suggest NAD⁺-boosting compounds may help manage weight and cardiometabolic risk in aging populations.

Insulin Sensitivity

Research indicates that NAD⁺ precursors like NMN may improve how the body responds to insulin, reducing the risk of type 2 diabetes and improving glucose control.
