Why Your Blood Needs Phosphorus

Why Your Blood Needs Phosphorus (Find Out Here)

We need phosphorus for our bodies to function well, but did you know that phosphorus is an important component of your blood?.

In this article we will explore the importance of phosphorus in our blood and why it is essential for optimal health.

We will also look at some of the common signs of low phosphorus levels and what steps you can take to ensure that your body gets enough phosphorus.

What is phosphorus and what does it do in your blood?

Phosphorus is a mineral contained in each cell in our body. Most phosphorus is in the bones and teeth, and some is in your genes.

Your body needs phosphorus to make energy and to carry out many important biochemical processes.

A sufficient intake of phosphorus is important as it plays a critical role in:

  • Maintaining structural component of bones and teeth
  • DNA/RNA synthesis
  • The bipolarity of lipid membranes
  • Circulating lipoproteins
  • Producing and storing energy in the form of ATP
  • Acting as a buffer for blood
  • Regulating gene transcription
  • Activate enzyme catalysis

Is phosphorus good for your blood?

Yes. Foods containing phosphorus is good for your health.

However, phosphorus in dietary supplements when taken in extreme amounts can cause serious health problems.

Here are some of the good reasons why your blood needs phosphorus.

Bone health

Phosphorus works closely with calcium to keep your bones strong and healthy.

Energy and DNA

Phosphorus is also involved in the production of energy in the form of ATP, and helps in the synthesis of protein DNA/RNA.

Acid-Base balance

Phosphorus helps to regulate the pH level of your blood.

pH is a measure of the acidity or alkalinity of a solution, and it is important that the pH of your blood is kept within a narrow range.

Phosphorus maintains this balance by acting as an acid-base buffer.

When the pH of the blood becomes too acidic, phosphorus helps to neutralize the excess acid, and when the pH becomes too alkaline, phosphorus helps to restore the balance.

Kidney health

Phosphorus is important for the functioning of the kidneys, which are responsible for regulating the amount of phosphorus in the body by filtering it out of the blood and eliminating it in the urine.

What foods provides phosphorus?

It is important to get enough phosphorus in your diet to maintain good health.

High-phosphorus foods:

  • Cottage Cheese
  • Custard
  • Yogurt
  • Peanut butter
  • Baked beans
  • Black beans
  • Chick peas
  • Kidney beans
  • Cocoa
  • Chocolate drinks

Low-phosphorus foods:

  • Apples
  • Apricots
  • Blackberries
  • Grapes
  • Tangerines
  • Peaches
  • Pineapple
  • Plums
  • Strawberries

Also, many processed foods have additives that contain phosphorus.

These additives are phosphoric acid, sodium phosphate, and sodium polyphosphate.

What about phosphorus dietary supplements?

Phosphorus is available in multivitamin supplements and some other dietary supplements.

Examples of phosphorus dietary supplements include dipotassium phosphate, disodium phosphate, or phosphatidylcholine.

Are you getting enough phosphorus?

Most people in the United States get more phosphorus than they need from the foods they eat. Groups at risk of phosphorus deficiency include:

  • Premature babies
  • People with certain rare genetic disorders
  • People with severe malnutrition

What happens if you don’t get enough phosphorus in your blood?

Phosphorus deficiency is rare. Not getting enough of this nutrient can cause:

  • Loss of appetite
  • Low red blood cell counts
  • Muscle weakness
  • Coordination problems
  • Bone pain
  • Higher risk of infection
  • Burning in the skin

When the levels of phosphorus in the blood becomes too low, it can lead to hypophosphatemia, which causes muscle weakness, fatigue, and impaired immune function.

How much phosphorus do you need?

The amount of phosphorus you need depends on your age. Average daily recommended amounts are listed below in milligrams (mg).

  • Birth to 6 months: 100 mg
  • Infants 7–12 months: 275 mg
  • Children 1–3 years: 460 mg
  • Children 4–8 years: 500 mg
  • Children 9–13 years: 1,250 mg
  • Teens 14–18 years: 1,250 mg
  • Pregnant teens: 1,250 mg
  • Adult 19+ years: 700 mg
  • Pregnant women: 700 mg

Does phosphorus interact with any other medications?

Yes, phosphorus can interfere with medicines that you take, and some medicines can affect phosphorus levels in your body.

Antacids, such as maalox, rulox, and rolaids, containing aluminum hydroxide can reduce the amounts of phosphorus your body absorbs.

Is phosphorus harmful to your blood?

High phosphorus in the blood can cause problems in healthy people. However, unless your doctor advises it, you shouldn’t consume more phosphorus from food, beverages, or dietary supplements than the recommended amounts.

The daily upper limits for phosphorus are listed below in
milligrams (mg).

  • Children 1–3 years: 3,000 mg
  • Children 4–8 years: 3,000 mg
  • Children 9–13 years: 4,000 mg
  • Teens 14–18 years: 4,000 mg
  • Adults 19–70 years: 4,000 mg
  • Adults 71+ years: 3,000 mg
  • Pregnant women: 3,500 mg
  • Breastfeeding women: 4,000 mg


Phosphorus plays important roles in your body by maintaining the proper balance of minerals in the blood, regulating pH of the blood, and supporting the functioning of the nervous system and kidneys.

It is important to get enough phosphorus from foods and dietary supplements to maintain good health.
