1. What is NAD?

NAD is a coenzyme derived from vitamin B3 (niacin or nicotinamide). It exists in two primary forms:

• NAD⁺ (oxidized form) – Accepts electrons in biochemical reactions.

• NADH (reduced form) – Donates electrons in energy production.

2. Functions of NAD

• Energy Production: NAD is essential in cellular respiration (glycolysis, Krebs cycle, and oxidative phosphorylation) to generate ATP, the body's main energy source.

• DNA Repair & Cell Health: It activates enzymes like PARPs (poly-ADP ribose polymerases) involved in DNA repair.

• Anti-Aging & Longevity: NAD⁺ is linked to activating sirtuins, proteins that regulate aging and stress resistance.

• Neuroprotection: Supports brain function and protects against neurodegenerative diseases like Alzheimer’s and Parkinson’s.

​3. How to Boost NAD Levels​

• Diet: Foods rich in niacin (meat, fish, mushrooms, avocados) help maintain NAD levels.

• Supplements: NAD precursors like NR (Nicotinamide Riboside) and NMN (Nicotinamide Mononucleotide) are popular for boosting NAD⁺.

• Exercise & Fasting: Physical activity and intermittent fasting naturally increase NAD⁺ levels.

• Reducing Alcohol Intake: Excess alcohol depletes NAD and impairs its functions.

4. NAD & Aging

NAD levels decline with age, leading to reduced cellular repair and increased risk of age-related diseases. Restoring NAD⁺ levels is being explored in anti-aging research.

5. NAD Therapy

NAD IV drips and oral supplements are being studied for their potential in improving energy levels, mental clarity, and overall health.
