I have used vitamin E for some time, while I was a bodybuilder, as it aids recuperation. But more recently I have been using it, as part of my regime to lower my high cholesterol.
I also do a lot of writing that demand a lot of intellectual, input. This is where it became apparent that vitamin E actually boosts intellectual competence. But that is not the whole story. It only works in intellectual favour if taken in the morning, which implies during the first three hours after you have wakened. If you take it after lunch or the evening it has no noticeable effect at all on boosting intellectual competence.
But, while that may seem appealing, there is one downer, in the equation of the practice. Taken in the morning vitamin E makes you moody and intolerant of anything negative you may encounter. This may not seem much, but those down points were to such extent that led to me changing the time I am taking vitamin E in the evening, before going to sleep. And I am now back to my cheerful and tolerant self, again. And I do not care if my books suffer as consequence, which will give you an idea of how bad the negative influence, was. But it does wonders for intellectual competence, which implies the negative effect on the emotions is a real shame.
The dosage I am taking is one 400 IU softgel capsule of vitamin E (as d-alpha tocopherol plus mixed tocopherols), daily.
The vitamin dosages suggested are mega doses, way above the RDA (Recommended Daily Allowance). So please do not follow on, on any tips I give here on this site from my own vitamin regime experiences, without first consulting a competent practitioner (doctor or nutritionist).
