Natural Vitamin E Plus Vitamin C in the Treatment of Alzheimer's Disease

Unfortunately, not all Vitamin E is the same. Natural Vitamin E is called d-alpha tocopherol. The synthetic form of Vitamin E is dl-alpha tocopherol. I asked several pharmacists if the natural and synthetic forms of Vitamin E were equally good antioxidants. Without exception, each of the pharmacists incorrectly informed me that the two were equivalent chemically, but that the synthetic form required a larger quantity to yield the 400 I.U. standard. Therefore, if a 400 I.U. natural Vitamin E was placed side-by-side with a synthetic Vitamin E softgel, the natural E softgel would be smaller than the synthetic E softgel. However, it turns out all of these pharmacists were dead wrong on the body’s ability to use synthetic Vitamin E as an antioxidant. The synthetic form of Vitamin E is an isomer of the natural molecule, but the body can readily detect the change. Whereas natural Vitamin E is a powerful antioxidant, the synthetic form of Vitamin E may or may not have any antioxidant properties for any given patient.
