Migraine is pretty individualized. Magnesium helps many people. For some it helps just a little, for some it makes a huge difference, for others it doesn't do much of anything. In short much to gain, not much to lose.
The only side effect that I'm aware of is that it can cause diarrhea (initially, as your body gets used to it), and this only occurs in some. So if this happens to you, not to worry, it's probably not the UC acting up.
I've been told, magnesium citrate (along with with malate) is one of the better absorbed Mg salts. A typical starting dose is 400 mg and you build up to 800-1200 mg (2-3 daily divided doses)
If your interested in finding out your Magnesium levels, get an RBC Mg blood test (different than an Mg serum blood test).
Other commonly used natural supplements: vitamin B2, feverfew and petadolex (butterbur). As always talk to your doctor before starting anything new, even supplements.
Like all supplements give them a few months before judging their effectiveness.
Best of luck!
