NAD+ Decline Drives Key Aging Processes
- NAD+ is a central cellular coenzyme that falls 40–60% with age and drives reduced mitochondrial energy, DNA repair, and increased inflammation.
- Restoring NAD+ in animals improves muscle, metabolism and reversed Alzheimer's models, but human lifespan benefits lack large-trial proof.
Do Fundamentals First Before NAD+ Supplements
- Prioritise fundamentals before considering NAD+ supplements: exercise, sleep and diet activate the same longevity pathways.
- If chosen, typical NAD+ support dosing is 250–500 mg in the morning plus mitochondrial cofactors and medical supervision.
Avoid Statins When Calcium Score Is Very Low
- If coronary calcium score is very low in older adults, avoid statins for primary prevention and congratulate lifestyle success instead.
- Use calcium score contextually; a score of 25 at age 73 gives minimal absolute benefit from statins.
