Kind: research · Impact: low

## In brief

- A study of more than 1,000 adults by Vilnius University researchers examined whole-blood NAD levels.
- Whole-blood NAD levels stayed stable with age in healthy men and rose slightly in women.
- NAD levels were lower in people with cardiovascular disease, particularly hypertension.

## Why it matters

The findings suggest blood NAD may reflect cardiovascular disease status rather than ageing alone, which matters for how NAD measurements are interpreted in research and clinical contexts.
