Maintaining adequate levels of vitamin D during winter months requires a daily dose four times the current recommended dose, according to a new study.
The study has important implications for ongoing consultations on vitamin D recommendations. The current level of five micrograms (200 International Units) is seen by many as insufficient.
While your body does manufacture vitamin D in response to sunlight exposure, the levels of sun in some northern countries are so weak during the winter months that your body makes no vitamin D at all.
Vitamin D deficiency can cause or exacerbate osteopenia, osteoporosis, muscle weakness, fractures, common cancers, autoimmune diseases, infectious diseases, cardiovascular diseases and diabetes.

There is no way to know if the above recommendations are correct. The ONLY way to know is to test your blood. You might need 4-5 times the amount recommended above. Ideally your blood level of 25 OH D should be 60ng/ml.
