Fair questions
Does vitamin E work?+
For mood, it is not settled. No real difference found so far.
Is vitamin E safe?+
No caution is recorded on this page. That is not a safety guarantee; the studies we read were not safety trials.
Why only 2 sources, when PubMed lists 6,062?+
The 6,062 is every paper that mentions vitamin E in any way: animal studies, blood measurements, papers where it is a side note. The strongest sources are combined reviews, and each one already gathers every trial its authors could find. Our 2 cover 10 trials between them, and every one is linked above. Both counts are measured, not estimated.
