Calcium (Calcium) – Function & Diseases

Calcium (Calcium)

The human body needs numerous minerals and trace elements to live. Since it cannot form most of the active substances it needs for its own life, they have to be supplied to the body with the diet. This also includes calcium (calcium) .

Effect of calcium (calcium)

Minerals, vitamins and trace elements influence each other. Therefore, the right interaction of all these active ingredients is necessary so that they are optimally available to the body.

Calcium (calcium) is a mineral that is commonly found in nature and is found in many foods. It is indispensable for humans, but also for plants and animals. Calcium is absorbed through the intestines and incorporated into the body through vitamin D , among other things.

Endogenous hormones help with this . The daily calcium requirement for an adult is around 800 milligrams. There is an increased need during pregnancy and breastfeeding.


Calcium is essential for building bones and teeth. Even with infants and young children, care is generally taken to ensure that the diet contains sufficient calcium and that children get enough outdoor exercise.

The mineral should be available to the body throughout life. Physical activity in the fresh air is also important for life. A high calcium intake alone is not enough. Moderate exercise, adapted to the respective age, is therefore essential.

In order for the mineral to be optimally incorporated into the body, it needs vitamin D, among other things. This vitamin, which belongs to the group of fat-soluble vitamins, can be produced by the body itself. Under the influence of physical exercise in the sunshine, vitamin D is formed in the human body.

Long-term calcium deficiency threatens osteoporosis in old age . Other diseases are also caused by the lack of calcium. If the body does not get enough calcium during the growth phase, bone softening and rickets , for example, can be further consequences of the calcium deficiency. Hyperexcitability of the nervous system and muscles (tetany) can occur. Dental health also suffers if the body does not get enough calcium.

Calcium absorption can be difficult at times. Coffee , alcohol and drinks containing sugar (e.g. cola) prevent the absorption of the mineral for some time. Magnesium also has this function. It is often sufficient to consume calcium-rich foods at a later time than those that impede the absorption of calcium. 

Therefore, if you do a lot of sport and therefore also consume magnesium, you should also think about calcium and take both minerals at a time interval from each other. Another antagonist of calcium is potassium . Among other things, it is responsible for the water excretion in the body. The more water the body loses, the more calcium is also excreted.

Occurrence in food

Calcium (calcium) is found in many foods. It is mainly found in dairy products. Long-ripened cheeses such as Parmesan, Emmental, medium-aged or old Gouda contain a particularly large amount of calcium. 

Of course it is contained in whole and skimmed milk as well as in yoghurt and quark. If you want to lose weight and therefore eat fewer calories, you are particularly at risk of not getting enough calcium.

But even people who suffer from lactose intolerance or an allergy to cow’s milk have to supply the body with calcium in other ways. For example, with a mineral water containing calcium.

In small amounts, calcium is found in almost every vegetable and fruit. Vegetables rich in calcium include kale, broccoli, endive, Swiss chard, leek, and spinach.
