I can't find info on the one from Myprotein, but one customer says it tastes great, which is always a bad sign.  the other powders i found contain 30-50% maltodextrin, i.e Glucose, which is exactly what you don't want in your MCT. Pure MCT is oil. I don't know anything about the process of turning oil into powder, but common sense says you don't want a chemical plant in your body.Forget the powder. Get the actual oil. You could probably find cheaper oil than any powder anyways.
