Half the people in Western Europe and North America get insufficient amounts of vitamin D. Elsewhere it is even worse!
Because two-thirds of the world population have insufficient vitamin D, the conclusion is that the vitamin we take from food it is not enough.
Currently, the recommended daily intake of vitamin D is 200 international units (IU) for people up to 50 years old; 400 IU for people 51 to 70 years old; and 600 IU for people over 70 years old.
Adequate intake of vitamin D is associated with decrease in the incidence of breast cancer, colon cancer and type 1 diabetes mellitus, the positive effect generally occurring within five years of initiation of adequate vitamin D intake
Vitamin D is converted into a steroid hormone by our organism. Its receptors are present in more than 37 target organs in the body (e.g. immune, brain, cardiovascular systems).
