## The Latest on Magnesium

A growing body of research continues to support what longevity scientists have been saying for years: Magnesium is one of the most promising compounds in the anti-aging space.

Involved in 300+ enzymatic reactions. Most adults are deficient. Critical for sleep, stress, muscle function, and heart health.

Recent findings published in Cell Metabolism suggest that Magnesium showed promising results for cardiovascular health markers. While more research is always needed, the direction of the evidence is clear.

## What the Science Says

The key benefits of Magnesium, according to current research, include:

- Sleep quality — supported by peer-reviewed studies
- Stress reduction — supported by peer-reviewed studies
- Muscle relaxation — supported by peer-reviewed studies
- Heart rhythm — supported by peer-reviewed studies
- Bone health — supported by peer-reviewed studies

What makes these findings particularly exciting is the consistency across multiple studies. This isn't a single paper making bold claims — it's a pattern emerging across the research landscape.
