Back in early 2016, I was looking into molybdenum-containing foods and realized that a regional diet study had found lower morning sickness in areas where the diets were high in legumes and whole grains, which happen to be the best commonly-eaten food sources of molybdenum (element #42). The grains that are high in molybdenum are oats and barley, not wheat.
While I was researching the morning sickness issue, I noticed that the nausea triggers were similar to migraine triggers. A friend who gets awful migraines decided to try molybdenum for her migraines since none of her prescribed medicines were helping her. She found that around 500 mcg of molybdenum glycinate could end her migraine even after it got started. No need to take it chronically. We both thought that was pretty cool, and so I told a couple of other migraine-sufferer friends about it. They also experienced dramatic relief from their migraines. Not bad for a supplement that costs less than $10 at our local vitamin store.
Molybdenum is used by five known enzymes in the body, one of which is sulfite oxidase. Sulfite oxidase, which converts sulfite to sulfate, catalyzes the final step in the process of breaking down endogenous (made in the body) hydrogen sulfide all the way down to sulfate (which is recycled or excreted in urine). Sulfites are known for making people sick, including with migraines and nausea. It looks as though migraines could be a result of excessive sulfite in our brains due to not being able to break sulfite down fast enough. Foods that interfere with sulfite oxidase (sulfites and nitrites, especially) do seem to be common triggers for migraines.
Do post if you try it. Maybe enough people will notice it helps them and spur a scientific study as to why it does so. The world definitely needs progress in migraine research!
