## Summary

NAD+ is the molecule your cells use to make energy and repair DNA, and levels drop as you age. This review looks specifically at menopause, when falling estrogen adds mitochondrial problems, inflammation and oxidative stress on top of normal aging. Precursors like NMN and nicotinamide riboside (NR) look good in lab and animal work. In people, results vary a lot and long-term safety data are still missing.

## Practical Takeaway

This review suggests NAD+ boosters remain unproven for menopausal health despite promising lab results.
