Phosphorus and calcium work together to build and maintain bones and teeth. 85% of the phosphorus in the body is combined with calcium in the bones.
The body also needs it to produce energy and DNA. In addition, phosphorus helps distribute lipids throughout the body and allows nutrients to cross the cell membrane.
Phosphorus is found in most foods, particularly those high in protein.
Dairy products, meat, fowl, fish, eggs, seafood, liver, nuts and legumes are excellent sources of phosphorus. Cereals also contain some but absorption is low.
Phosphorus is also present in food additives found in prepared foods.

Recommended average daily nutrient intake that is sufficient to meet the nutrient requirements of nearly all (97 to 98%) healthy individuals in each age and gender group. The RDA should only be used as a guide for daily individual intake.
A varied diet should easily provide adequate amounts of phosphorus.
Deficiencies are uncommon. They occur mostly in premature babies who need significant amounts of phosphorus and in people who ingest large quantities of aluminium-containing antacids which reduce the absorption of phosphorus.
A phosphorus deficiency is characterized by a loss of appetite, reduced bone mass, brittle bones, muscle weakness, stiff joints and increased susceptibility to infections.
Toxicity generally occurs in the presence of kidney failure as the body is unable to eliminate the excess phosphorus. The excess leads to an imbalance between the phosphorus and the calcium and causes bone demineralization and bone pain.
To resolve the problem, phosphorus intake is restricted and products such as calcium, which decrease the absorption of phosphorus, are taken.
Since phosphorus is commonly found in the foods we eat, supplements are not necessary.
