Vitamin D3 (Cholecalciferol)
Our body uses uv light from the sun to produce vitamin D, so strictly speaking vitamin D is not a vitamin.
The main function of vitamin D is to regulate the serum calcium and phosphorus concentrations. Vitamin D improves the absorption of calcium and phosphorus in the intestines. In case of vitamin D deficiency, only 10% to 15% of calcium is absorbed. With adequate presence of vitamin D, calcium absorption increases by up to 30% to 40%.
Vitamin D plays an important role for many more body processes:
- is important for normal muscle function
- is good for the cell division process
- also ensures good resistance
- plays a role in calcium management
- is necessary for normal growth and development of children’s bones
- increases the absorption of lime in the bones
- supports children’s immune systems
- contributes to strong teeth
- Vitamin D helps to reduce the risks of falls, due to posture instability and muscle weakness. Falling is a risk factor for bone fractures in men and women over the age of 60. (at least 15 micrograms of vitamin D per daily serving)
