A vital component of the bones and teeth, phosphorus is important to protecting against osteoporosis. Along with this function, phosphorus is also part of the nucleic acids, phospholipids, ATP and a number of different enzymes and coenzymes in our body that regulate the metabolism.

Phosphorus is most commonly found in beans, peas, milk, cereals and nuts and is well absorbed by the intestines. Most often you will not see a deficiency in phosphorus in individuals as almost everyone gets enough, however if there is a chronic use of excessive anticonvulsants, calcium carbonate supplements or aluminum hydroxide-containing antacids occurring, this can decrease the rate at which it is absorbed by the body and that can lead to a deficiency. Deficiency then can cause a bone loss, feelings of weakness and a poor appetite.

On the other hand, high levels of this mineral in the blood can be due to inadequate renal filtration or acute or chronic renal failure. An imbalance of calcium and this mineral in the body can also cause problems so it is important to monitor any supplemental sources you are taking. The upper intake levels are set for 4000 mg per day for both men and women until the age of 70 at which point the highest dosage recommended comes down to 3000 mg. The recommended dosage for good health however is only 700 mg/day.
