What it is
NAD+ is a coenzyme present in every cell, essential to the reactions that turn food into ATP and that maintain DNA integrity.
How it works
Acts as a coenzyme in hundreds of reactions including those carried out by sirtuins, a family of enzymes implicated in cellular ageing.
The protocol
Follow product-specific dosing for NAD+ precursors. Effects are systemic and accrue over time.
Sourcing
Look for branded, third-party tested NR or NMN. Honest dosing matters more than marketing.
Honest caution
Long-term safety data is still maturing. Discuss with a clinician if pregnant, nursing or on medication.
What it supports
- Cellular energy — Supports the reactions that convert food to usable cellular energy.
- DNA maintenance — Coenzyme for the enzymes that maintain DNA integrity.
