Roll Call does not check drug interactions or assess personal safety.
An essential mineral, second most abundant in the body after calcium, found in protein-rich foods such as meat, dairy, and grains.
Why it’s used
Taken to support bone and teeth structure, energy metabolism, and cell membrane function, though most people get enough through diet alone.
What the evidence is for
bone mineralization and cellular energy metabolism.
What the evidence says
NIH ODS confirms phosphorus's established role in bone mineralization and cellular energy metabolism via ATP. Deficiency is uncommon in people eating a varied diet, and supplement use is generally to correct low levels rather than to produce a standalone benefit in well-nourished people.
Dose studied
700–4000 mg — adult RDA up to the tolerable upper intake level, per NIH ODS.
Context
The adult RDA is about 700 mg/day, with a tolerable upper intake level of 4,000 mg/day per NIH ODS.
