@ddljohn-- I think there may be two different types of vitamin E suppositories out there, I'm not sure. I personally use vitamin E vaginal suppositories. These are recommended by doctors for some women to treat vaginal dryness and other issues that occur after menopause. I find them very helpful and have been using them for several weeks now.
I don't know if rectal vitamin E suppositories are sold separately or if people use the same product. But I'm sure that others vitamin E suppositories rectally to treat other conditions or a deficiency.
