I use a combination product with magnesium threonate, maleate and biglycinate. It seems to work well, and avoids the diarrhea that can happen with magnesium citrate.

My answer wouldn't be helpful. I also have fibromyalgia and I'm low on magnesium, so I take a lot of magnesium at every meal. However, in case you didn't know, Magnesium L-threonate has the ability to pass over the brain barrier more easily. I suggest you take it in the morning because it tends to give you a little boost in energy. I take what is prescribed on the bottle.

I take 250 mg daily Magnesium. Pain management specialist suggested this would be quite helpful for the chronic migraines.

Hi. I also take Magnesium L-threonate in high doses the buzzing returns. and it stills my head from buzzing though if I take too much [often magnesium is also included in lots of vitamins/minerals] It is pricey but so worth it!
