Good question, I should have mentioned it earlier. There are 5 types of Vitamin D,- D, D1, D2, D3, D4 but our bodies only use D2 & D3. Clinical trials show that D3 is superior to D2. Newer studies now show D3 is twice as effective as D2 probably because it binds to proteins better. My problem is I took two of the worst Anticonvulsants for getting rid of Vitamin D Dilantin and Phenobarbital. These drugs increase activity of enzymes in the liver which causes Vitamin D to be broken down into inactive forms of Vitamin D. Vitamin D is absorbed
In the intestines but Thyroid problems hinder that absorption. Some researchers believe people 65 and over are all in need of Vitamin D to help fight off disease. Another important fact regarding Vitamin D is adequate levels D helps reduce adverse reactions of some meds. Vitamin D has many vital functions to keep us healthy and should not be ignored.
Most people don’t understand the sun and vit D which is confusing to me but you only need about 15 minutes in sun several times a day but the angle of the sun is vital and other factors like pollution, clouds, sun screen, cloths etc. Also only UVB rays can be used by the body. If your in a car or sitting in the sun behind any glass it won’t help. UVA rays go through glass but only age your skin. Whenever your in the sun and your shadow is shorter than you are your in luck. But don’t overdue it. Eat healthy and eat foods fortified with vit D. Always ask your doctor if a new or current prescription is going to affect you Vit D levels.
