Vitamin E has different activities, and the best one comes from wheat germ. For example, Amway's soybean extract is poor, while Yangshengtang's is, and you should buy natural extracts, not synthetic ones, which have worse activity, such as those with very cheap drugs.

As for the effect difference you mentioned, the effective component of vitamin E in Yangshengtang is 97mg, while that in Amway is only 18mg. Of course, taking one pill a day will have a different effect. If you take five Amway pills, it must be Amway's effect, so Amway's is much more expensive.

As for the effect, vitamin E is characterized by anti-aging, anti-oxidation, better wound recovery, whiter skin and fewer spots.
