The effect of vitamin E capsule depends on the content of VE in the capsule. You only need to look at the content of VE in each capsule, that is, the content of d-α- tocopherol. If it is very low, this VE capsule is not good. Although the names are all called vitamin E capsules, they are very different, because many VE capsules are not all VE ingredients, and many health care products capsules are also filled with many impurities. The tocopherol purity of health care product VE is generally much lower than 40%. If a vitamin E capsule indicates that each capsule contains 97.5 mg of d-α- tocopherol and each capsule weighs 250 mg, the actual VE purity is only 39%.
