Information on vitamin D3

Do you have unexplained health problems? This may be due to a vitamin D deficiency.

On this website we will inform you about the symptoms and solutions with a vitamin D deficiency. 

Vitamin D is important

Vitamin D is important for strong bones and teeth. It promotes the absorption of calcium and phosphorus into the body. Vitamin D is good for resistance and ensures the proper functioning of muscles. The body gets vitamin D from food and sunlight. 

Vitamin D deficiency detected in

  • 40 % of the total population
  • 32% of doctors and medical students
  • 42% of African-American women
  • 48% of girls aged 9 to 11 years old
  • 76 % of pregnant women
  • 81% of babies born to these women
  • Up to 60% of all cancer patients
  • Up to 80% of elderly people in nursing homes

Vitamin D supplements

In the USA or the Netherlands, capsules with 50,000 units are freely available by mail order. 

Tablets - preparations with 1,000 units and less are not suitable for vitamin D therapy in view of the high doses required, because the patient ingests unnecessarily many additives.

VITAMIN D: Mcg = iU (international units)
5 mcg = 200 iU
10 mcg = 400 iU
20 mcg. = 800 iU
50 mcg. = 2.000 iU
500 mcg. = 20.000 iU

Vitamin D deficiency is the cause of many diseases and is widespread. Severe deficiency can lead to cramps, muscle twitching and muscle pain, restlessness, sleep disorders and depression, exhaustion, weakness, backache and headache, a feeling of coldness in the hands and feet, as well as circulatory and circulatory disorders. For all these complaints and diseases, rapid improvement and permanent healing is often possible.

If vitamin D deficiency persists for a long time, the risk of high blood pressure, diabetes, osteoporosis, autoimmune diseases, multiple sclerosis and cancer increases. To avoid this, an optimal vitamin D level should be aimed.
