## Summary

In over 2,000 young and middle-aged adults in China, higher vitamin D levels were linked to a lower chance of early vascular aging (stiffer arteries than expected for your age). The benefit kicked in below a threshold of about 18 ng/mL, with each 10 ng/mL bump tied to 19% lower odds. The link was strongest in men and people with overweight or obesity.

## Practical Takeaway

This study suggests keeping vitamin D above roughly 18 ng/mL may be associated with healthier artery aging.
