Four Times the Recommended Vitamin D Dose Needed for Winter
March 28, 2009
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.
|Vitamin D Dose Recommendations

|Age 18 - 30
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.
