You have to be careful with statements like this. Normally, the vitamin E content in a capsule is given in IU and there is no difference between e.g. 400 IU of synthetic form of vitamin E and 400 IU of the natural form. Both have the same biological activity. However, the capsule containing the synthetic form of vitamin E will be larger since it contains a larger amount of fluid.
