It’s not clear to me why vitamin/fructose ratio would even be important?
Generally vitamins aren’t helpful unless you were deficient, which is uncommon in western diets.

Vitamin B (thiamine) deficiency is also common among alcoholics. Lots of heavy drinkers out there. While obviously drinking less is the preferred solution, if they aren't willing to do that then supplements can reduce the harm.

Before you go all in on the supplements (a) get measured for vitamin D levels first and (b) if you're anywhere in the ballpark of replete (you probably are) then make an effort to get outside, often, and without sunscreen. To the extent you don't get burned of course.
