I have vestibular migraines as well. I tried B2 but the high dose irritated my bladder, which can be a side effect of therapeutic dosage. My neurologist recommended Vitamin B-12, Magnesium L-Threonate (specific type that crosses the blood-brain barrier more effectively to treat migraines than regular magnesium), and CoQ10- they also recommended but I haven’t tried it yet. I also use Boswellia Serrata and Sam-E airtight tablets. My naturopath (primary) said fish oil can also be good.

I use B12, coq10 and magnesium. Among many other supplements. I think it all helps. Keep using it because it does help

I've had MD and VM gor 4 years. Eating clean, avoiding salt for many. Caffeine

There are better support groups on FB. Menieres Disease support groups who most have VM. Try those..you can see much more info, from 1 000's if people all over the world. I'm going back there..sorry.
