Introduction: The importance of calcium

Calcium is an essential nutrient that is vital for the health of bones, teeth, muscles and nerves. Its importance extends far beyond the structure of the body and influences numerous physiological processes.

The role in the body

Bone and tooth strength: It is the building block for the strength of bones and teeth. It makes up the majority of the mineral substance in bones and is crucial for their strength and structure.

Muscle contraction: It plays an essential role in muscle contraction, including the heart muscle. It is involved in the release of neurotransmitters required for signaling between nerves and muscles.

Nerve function: It regulates the transmission of nerve impulses and is responsible for the release of neurotransmitters that are essential for communication between nerve cells.

Blood clotting: It is involved in blood clotting by activating certain enzymes necessary for the formation of fibrin, a protein that forms blood clots.

Calcium deficiency and health effects

A lack of calcium can cause serious health problems. Symptoms of a deficiency include osteoporosis, dental problems, muscle cramps, numbness in the fingers and toes and an increased susceptibility to bone fractures.

The importance of calcium supplements

Calcium supplements can be an important supplement for people who cannot get enough minerals from their diet. They are available in various forms such as calcium carbonate, calcium citrate and calcium lactate. Each form has its own advantages and disadvantages in terms of bioavailability and tolerability.

Combination with other food supplements

The effectiveness can be enhanced by the right combination with other supplements. Some important supplements that can be combined are:

1. Vitamin D: Vitamin D plays a critical role in the absorption in the intestines. It promotes calcium absorption and helps maintain healthy levels in the blood.

2. Magnesium: Magnesium works closely with calcium and supports its absorption and utilization in the body. Adequate magnesium intake is therefore important to reap the full benefits.

3. Vitamin K: Vitamin K plays a role in regulating calcium metabolism in the body and is important for bone health. It can help promote bone mineralization and prevent osteoporosis.

Calcium and diseases

It can also play an important role in the prevention and treatment of certain diseases, including

1. Osteoporosis: Osteoporosis is a condition in which bones lose density and strength. Adequate intake, along with vitamin D and regular physical activity, can help reduce the risk of osteoporosis.

2. Hypertension: Some studies suggest that adequate intake may be associated with a lower risk of high blood pressure. It can help relax blood vessels and lower blood pressure.

3. Premenstrual syndrome (PMS): It can help women suffering from PMS by relieving symptoms such as mood swings, irritability and water retention.


Calcium is a vital nutrient that supports a variety of functions in the body. Adequate it intake is crucial for strong bones, healthy teeth, proper muscle and nerve function and the prevention of certain diseases. By combining it with other important nutrients such as vitamin D, magnesium and vitamin K, the health benefits of this mineral can be maximized. It is important to have a balanced diet and take supplements if necessary to ensure that the body is supplied with sufficient calcium.
