## Summary

Long-term vitamin C given to monkeys helped keep their bone marrow younger, the factory that makes blood and immune cells. The supplement rebuilt a pool of cells that normally shrinks with age. By two different aging clocks, the treated marrow looked about 4 years younger. This is early animal work, but it hints at why vitamin C matters for a healthy immune system.

## Practical Takeaway

This study suggests vitamin C may support the cells that keep your immune system young.
