If you decide to take vitamin D you should have a look at that it is in the D3 form and not D2. D3 form raises vitamin D blood levels much more than D2. Most adults require about 5,000 IU of vitamin D daily for optimal health. This applys to pregnant women too. You can also count your daily need: 35 IU's of vitamin D per pound of body weight. Usually softgel capsules where vitamin D is dissolved in oil are better than tablets. It is more beneficial to take vitamin D daily than larger amount once a week.
You should test your blood level of vitamin D about four weeks after starting oral vitamin D. The optimal value of vitamin D that you're looking for is currently 50-70 ng/ml. To treat cancer or heart disease 70 -100 ng/ml is recommended.
