My wife was advised to take as pure as possible a vitamin E supplement as she could find, but all “pure vitamin E oil” products I have found seem to be for skincare rather than consumption as a supplement.

I understand d-alpha tocopherol to be the “best” form of vitamin E, but find liquid forms often contain sunflower or other oils, which I understand to be a source of but of course are not entirely vitamin E.

Is a pure liquid supplement possible? And if not, or if it is not common or not advisable, why?

Looking at E vitamin products sold commercially, all “pure vitamin E oil” products seem to be for skincare rather than consumption as a supplement.

I have read that d-alpha tocopherol is the form of vitamin E with greatest bioavailability, but even liquid supplement products often contain sunflower or other oils in addition, which I understand to be a source of but of course are not entirely vitamin E.

Is a pure liquid supplement possible or practical for consumption as a supplement, and if not, why?
