I live in South Texas, am out in the sun on a regular basis and am fair skinned. So I assumed I did not have to worry about a Vitamin D deficiency. Besides, my multiple contains Vitamin D. So I have no obvious risk factors for a deficiency. Last December I saw a GI doctor who tested me for a lot of stuff, including Vitamin D, which revealed I had plenty. Well, I recently learned from another doctor that the GI doctor measured the wrong form of Vitamin D. Apparently (if I understood my doctor), we get Vitamin D2 from our food. With the sun’s help our bodies convert Vitamin D2 (which our bodies cannot use) into Vitamin D3 (which is what our bodies do use). When my Vitamin D3 levels were tested a severe deficiency was revealed. My doctor said new research suggests we may actually need 5000 IU per day. So I am currently taking 5000 IU twice a day and will be tested in 3 months. My point, if you get your Vitamin D levels tested, make sure your doctor tests D3 and not D2. Also, make sure the Vitamin D you are taking is D3 (Cholecalciferol) and not D2. It won’t do you any good if your body is unable to convert the D2 into D3.Reply Follow This Thread Stop Following This Thread Flag this Discussion
