They also make cell membranes throughout the body less stiff and more flexible. Two small double blind studies found that high dose fish oil supplements reduced the frequency of headaches in people who chronically suffer. Requires a six week trial. May help the nausea and vomiting that occurs with acute migraines, since it helps the nausea of motion sickness. Several cases where it helps have been reported, but as of this writing, no double-blind studies.
Magnesium helps muscles relax.
These individuals, but not those with normal magnesium, improve dramatically when given intravenous magnesium during a migraine attack. Indirect evidence suggests that ongoing supplements with oral magnesium may also have a preventive anti-headache effect, but as of this writing we do not have double blind studies to prove this. Personally, I doubt that the success rate is that high, but I do recommend magnesium for at least a two month trial for nearly all of my migraine patients. In a double blind study two groups are selected. One group is given a placebo while the other is given the medication being studied.
