Your mitochondria are running on fumes. Not metaphorically—literally. By age 50, NAD+ levels in human tissue have dropped roughly 50% from youthful baselines. This coenzyme, nicotinamide adenine dinucleotide, sits at the center of every major energy transaction in your cells: glycolysis, the TCA cycle, oxidative phosphorylation, DNA repair, and the sirtuin-mediated stress responses that keep genom

Key Findings
- Comprehensive review of NAD+ precursors (NMN, NR), their role in mitochondrial function, sirtuins, and DNA repair
- Examine human clinical trial data, optimal dosing, and what we still don't know
Practical Takeaways
- Review the evidence on NAD+ with your healthcare provider
- Evidence-based protocols are detailed in the full article
