Phosphorus

The energy mineral in every cell of your body.

Deficiency is uncommon; excess from food additives is a greater concern for most adults

Why it matters for longevity

Phosphorus is the second most abundant mineral in the body and is essential for ATP energy production, bone mineralization, DNA and RNA structure, and cell membrane integrity. While deficiency is rare in Western diets, the ratio of phosphorus to calcium matters for bone health. Excess phosphorus from processed foods and soda is associated with accelerated aging and cardiovascular calcification.
