Vitamin E, what is it?
Tocopherol, tocotrienols…what are they?

It can also reduce the risk of prostate cancer (and here the results are conflicting) and cataracts.

Vitamin E deficiency is rare in healthy people in industrialized countries. It is almost always associated with certain diseases in which fat is not properly digested or absorbed (Crohn’s disease, cystic fibrosis, and certain rare genetic diseases such as abetalipoproteinemia and vitamin E deficiency ataxia). Vitamin E needs fat to be absorbed by the digestive system.

How to take a vitamin E dietary supplement? Which vitamin E to choose?
In dietary supplements, vitamin E is almost always alone as alpha-tocopherol. High doses of alpha-tocopherol displace gamma-tocopherol, an isomer of vitamin E important for health. Therefore, preference should be given to small doses.
Complicating everything are the forms of vitamin E: synthetic and natural. Natural vitamin E (alpha-tocopherol) is twice as bioavailable as synthetic vitamin E. LaNutrition.fr recommends giving preference to supplements containing the 8 isomers of vitamin E (which is rare), also favoring natural forms and avoiding taking more than 100 IU doses of alpha-tocopherol per day, unless medically indicated.
LaNutrition.fr recommends giving priority to offering supplements 8 isomers of vitamin E (which is rare) as well as favour natural formsand avoid doses greater than 100 IU of alpha-tocopherol per day unless medically indicated.
