Here some (incomplete) updates
I asked nowfoods and their answer was: "The mixed tocopherol content is a minor component of the E-400 and we do not test for these.
Consider this more comprehensive formula to meet your needs:
https://www.nowfoods.com/supplements/advanced-gamma-e-complex-softgels"
(Unfortunately I bought 250 softgels of e-400...)
Until now, nobody knows the correct ratio between Alfa/Gamma. Somebody says 4:1, others 1:1.
I suppose a good ratio is the same found in a heathy diet. But what is this ratio ?
Some company add tocotrienols in the complex, and others not.
Until now, I found these products
