Patient discussion about IU
Q. my Dr. said to take no more than 400 iu of Vit. E. But I noticed my multiple also has 200 IU. Is this bad? I have been taking 400 units to combat Peyronies. I noticed today that my Centrum Silver also contains Vitamin E. I know taking over 400 units can be toxic, so now which way do I go from here. Thanks for any info.
A. in general, an over dose is not a very smart thing to do also in vitamins. and taking to consideration that you may have a diverse amount of vitamin E in your diet..well..you may take too much. but i have to be honest with you- i'm not a Doctor. and the one i would ask in that matter is my Doctor. all you need to do is phone him.
