Phosphorus is a mineral that makes up 1% of a person's total body weight and is present in every cell of the body. It is naturally found in many foods and is also available as a supplement. Phosphorus is essential for building strong and healthy bones and teeth, and it plays a crucial role in how the body uses carbohydrates and fats. It is also necessary for the body to make proteins for the growth, maintenance, and repair of cells and tissues. Additionally, phosphorus helps the body create ATP, a molecule that stores energy, and it works alongside calcium and B vitamins to support nerve and muscle function. While most people obtain sufficient phosphorus through their diet, those with specific health conditions may require phosphate supplements, which can have side effects and interact with medications.

What You'll Learn
Phosphorus and bone health
Phosphorus is a mineral that makes up 1% of a person's total body weight. It is the second most abundant mineral in the body and is present in every cell. Most of the phosphorus in the body is found in bones and teeth, with about 85% of the body's phosphorus present in these areas.
Phosphorus is needed to build strong, healthy bones and plays an important role in bone augmentation and maintenance. It is also crucial for the growth, maintenance, and repair of all tissues and cells. Phosphorus works with calcium to support bone health. The two minerals interact in the gastrointestinal tract to limit the absorption of the other and are intimately related in tissue. A balance of dietary calcium and phosphorus can lower the risk of osteoporosis.
Phosphorus is widely distributed in many foods, including meat, milk, grains, and protein-rich foods. It is also added to food as an additive or preservative (inorganic phosphorus) and is found in fast foods, ready-to-eat foods, canned and bottled drinks, enhanced meats, and most processed foods. Phosphorus from food additives is completely absorbed.
Excessive dietary phosphorus has been associated with adverse effects on bone and mineral metabolism. High dietary phosphorus, particularly when combined with low dietary calcium, reduces bone mass. This can lead to osteoporosis and teeth problems. However, it is important to note that phosphorus intakes below 70% of the RDA will also be low in other key nutrients, including calcium and protein, which are critical for bone maintenance and repair.

Phosphorus in food additives
Phosphorus is a mineral that makes up 1% of a person's total body weight. It is the second most abundant mineral in the body, present in every cell. Most of the phosphorus in the body is found in bones and teeth. Phosphorus is needed to build strong, healthy bones and teeth, and to keep other parts of the body healthy. It also plays an important role in how the body uses carbohydrates and fats, and is needed for the body to make protein for the growth, maintenance, and repair of cells and tissues.
Phosphorus from food additives is completely absorbed. Phosphorus additives are found in fast foods, ready-to-eat foods, canned and bottled drinks, enhanced meats, and most processed foods. Phosphorus additives are also common in frozen foods, dry food mixes, packaged meat, bread and baked goods, soups, and yogurt. In fact, phosphorus additives were found in as many as 44% of food items available for sale in the United States.
Phosphorus additives are added to convenience and processed foods for leavening, colour and moisture retention, anti-caking, and flavour enhancement. They are also added to foods to provide certain nutrients, as phosphorus works with B vitamins and is needed for the body to make protein.
However, high levels of phosphorus in the blood only occur in people with severe kidney disease or severe dysfunction of their calcium regulation. Individuals living with reduced kidney function are at risk of hyperphosphatemia due to reduced excretion of phosphorus in the urine. For those with hyperphosphatemia, it is recommended to reduce dietary phosphorus intake. One strategy to reduce phosphorus intake is to limit the consumption of foods containing phosphorus additives.
It is important to note that reporting of phosphorus content on nutrition facts tables is not currently mandated. When phosphorus content is described, it may be reported in relative terms (percent daily value) rather than the absolute quantity (milligrams of phosphorus). For those seeking to limit their phosphorus intake, this may create additional challenges as the percent daily values will be reported as lower amounts despite no change in phosphorus content.

Phosphorus and kidney health
Phosphorus is a mineral that makes up 1% of a person's total body weight. It is present in every cell of the body, with most of it found in bones and teeth. Phosphorus is needed to build strong, healthy bones and teeth, and to keep other parts of the body healthy. It also plays an important role in how the body uses carbohydrates and fats, and is needed for the body to make protein for the growth, maintenance, and repair of cells and tissues.
Phosphorus can be found in foods (organic phosphorus) and is naturally found in protein-rich foods such as meats, poultry, fish, nuts, beans, and dairy products. Phosphorus found in animal foods is absorbed more easily than phosphorus found in plant foods. Phosphorus that has been added to food in the form of an additive or preservative (inorganic phosphorus) is found in fast foods, ready-to-eat foods, canned and bottled drinks, enhanced meats, and most processed foods. Inorganic phosphorus is completely absorbed, so avoiding phosphorus additives can lower your phosphorus intake.
For people with chronic kidney disease (CKD), the kidneys cannot remove phosphorus well. Extra phosphorus causes body changes that pull calcium out of bones, making them weak. High phosphorus levels can also combine with calcium, leading to dangerous deposits in the blood vessels, lungs, eyes, and heart. This can, over time, cause an increased risk of heart attack, stroke, or death. Studies have also shown that high phosphorus levels may directly harm the kidneys and cause a loss of kidney function.
Dialysis can remove some phosphorus from the blood. To keep phosphorus levels normal, it is important to understand your diet and medications for phosphorus control. A dietitian who works with kidney patients can help plan a low-phosphorus diet. Your healthcare team may also order a medicine called a phosphate binder to help control the amount of phosphorus your body absorbs.

Phosphorus supplements
Phosphorus is an essential mineral that plays a crucial role in maintaining good health. It is abundantly present in the body, with most of it being stored in the bones. Phosphorus works closely with calcium to build strong bones and teeth. Additionally, phosphorus is a component of every cell in the body and is involved in various metabolic processes that generate energy and support organ function.
Including phosphorus in your diet is important to maintain healthy phosphorus levels. Phosphorus-rich foods include meat, fish, dairy products, eggs, nuts, and beans. Whole grains and bread are also good sources. However, the body's ability to absorb phosphorus from food decreases with age, and certain medical conditions or medications can impact phosphorus absorption and excretion.
In such cases, phosphorus supplements may be recommended to ensure adequate intake. Phosphorus supplements are typically available in tablet or capsule form and can be purchased over the counter. These supplements usually contain phosphorus bound to another substance, such as sodium, calcium, or potassium, to enhance absorption.
- Dosage: The recommended daily intake of phosphorus for adults is around 700 mg. However, the optimal dosage of phosphorus supplements can vary depending on age, diet, and health status. It is always best to consult with a healthcare professional to determine the appropriate dosage for your specific needs.
- Side effects: Excessive phosphorus intake can interfere with the absorption of other minerals, such as calcium, iron, and magnesium. Therefore, it is important not to exceed the recommended dosage of phosphorus supplements to avoid potential side effects, including digestive issues and an increased risk of kidney problems.
- Interactions: Phosphorus supplements may interact with certain medications, including antibiotics, antacids, and blood thinners. Inform your healthcare provider about any medications or supplements you are currently taking to assess the risk of potential interactions.
