some forms of e are better than others. it may be the case they used an inferior form of vitamin e. if so it was probably deliberate to get these desired results so they can continue the smear against supplements.
I have a chart that resulted from the most extensive study of all the known research studies on nutrition supplements.
In spite people’s own beliefs that they “feel better” sometimes, there is little evidence to support the vast majority of them as supplements.
Eat good amounts of the kinds of foods that have good stuff for you, because the artifiicial way has been studied and found to be no “supplement” for basic good nutrition.
If you want I will post it again; or a link to it. It even has links to all the studies that were analyzed and for each study links for the data from them. It was the most exhaustive report on the subect I’d ever seen.
