As a supplement
Talk to your doctor or pharmacist.
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.

How much is a reference amount
- 700 mg a dayfor adults 19–50 · Recommended Dietary Allowance
Upper limit 4,000 mg a day, from food and supplements together.
- 700 mg a dayfor adults 51–70 · Recommended Dietary Allowance
Upper limit 4,000 mg a day, from food and supplements together.
- 700 mg a dayfor adults 71 and over · Recommended Dietary Allowance

The RDA is flat across adulthood; only the UL moves, dropping at 71. Three rows exist solely because intake and limit share a row.
Every applicable line is shown because we don’t know which one is yours, and a reference intake is a target for a population, not a threshold for harm.
