The Science Behind NAD+

The Biology
NAD+ is the essential co-enzyme that shuttles electrons in redox reactions to make ATP and supports mitochondrial maintenance and DNA repair (PARPs/sirtuins).
How This Helps
More reliable daily energy, improved recovery after stress, and better cellular repair capacity.
Key Nutrients
• NAD⁺ (500 mg) • Resveratrol (150 mg) • Quercetin (250 mg)
The Biology
NAD+ availability influences neurotransmitter synthesis and neuronal metabolism. Quercetin promotes cellular autophagy, and resveratrol activates SIRT1 pathways linked to brain resilience.
How This Helps
Cleaner mental energy, better focus, and steadier mood throughout the day.
Key Nutrients
• NAD+ • Quercetin • Resveratrol
The Biology
Quercetin and resveratrol are polyphenol antioxidants that counter oxidative stress and support vascular function while NAD⁺ supports cellular longevity programs (sirtuins).
How This Helps
Stronger cellular defenses and age-smart vitality.
Key Nutrients
• Resveratrol • Quercetin • NAD+
