Calciferol

Calciferol, also known as vitamin D, is a fat-soluble vitamin that plays an important role in regulating the levels of calcium and phosphorus in the blood and maintaining bone health.

This vitamin can be obtained in two ways: synthesized under the influence of sunlight in the skin or obtained through food and supplements.

Calciferol has a number of functions in the body:

• Aids in the absorption of calcium and phosphorus from food in the intestines.
• Supports normal mineral levels in the blood for the functioning of the nervous system, muscle function, and cellular processes.
• Is important for the growth and development of bones and teeth.
• Prevents bone softening (osteomalacia) in adults and rickets in children.

Calciferol and the Keto Diet

In the context of the keto diet, it is especially important to ensure an adequate intake of calciferol, as excluding certain foods can lead to a deficiency of this vitamin.

Main sources of vitamin D on the keto diet:

• Fatty fish such as herring, salmon, mackerel, and tuna.
• Liver.
• Eggs (especially yolks).
• Mushrooms grown under UV light.
• Dietary supplements with vitamin D, if recommended by a doctor.

To optimize the synthesis of vitamin D by the skin, it is also necessary to ensure adequate exposure to sunlight.

Possible Risks of Calciferol Deficiency

With a deficiency of calciferol, the following problems may arise:

• Deterioration of bone health, increased risk of fractures.
• Muscle weakness and pain.
• In children – rickets.
• In adults – osteomalacia or osteoporosis.
