Can to much Vitamin A from food cause headaches?

Answered on August 19, 2014

I have always been a constant migraine/headache sufferer and been on constant medicine but lately I have been getting more than normal. I have been keeping a food diary to keep track and trying to find a new trigger and the only thing I can think of is that my vitamin A levels are extremely high like over 1000 mg a day from kale, spinach, squash or sweet potatoes? It usually is pretty high lately on a day to day basis and thats the only thing I can think of that has increased lately. I was just wondering if anyone knows if there is any correlation? Getting sick of taking my migraine pills! Thanks!

The only studies done on oral magnesium absorption were done with magnesium oxide, and your neurologist is correct, only about 4% of that is absorbed, and taken long term can cause diarrhea leading to mineral deficiencies, including magnesium. Magnesium glycinate is far less of a laxative, and many people do report significant benefit with headaches. Magnesium glycinate is perfectly safe to take long term. Most people eating foods grown in modern soil are mag. deficient, unless the soil is replenished with something like seaweed or fish fertilizer.

I have no idea if vitamin A could be a culprit, but have you looked into histamine intolerance? A lot of foods on this diet like broth, lacto-fermented veggies, leftover meats from batch cooking, etc. are all high histamine foods and can cause headaches in some people.

I'm with Travis, I'm a bit befuddled about the long term comment. Still, for Mg I can recommend the glycinate and Epsom salts.

Not good long term? But the pharmaceuticals are? Not sure if srs. Anyway, it takes a while of having a positive magnesium balance before it will significantly affect serum levels.

Thanks! I asked my neurologist about magnesium and he said no since only a small amount actually gets absorbed and it is not good long term.. Tried it for a while since it seemed to help my stomach issues for a little but no help with headaches.

That's basically impossible from beta-carotene since the conversion is so low. What you should look into though is magnesium glycinate, as many have stopped having migraines as a result of supplementation with it.

For what it's worth, I've determined that I've been quite low on preformed vitamin A and have taken over 300,000IUs of it in the past few weeks and have had no perceptible changes except improvements in my skin. So yeah, a little beta-carotene isn't going to do anything. I'd wager that you're still low on it, especially if you take vitamin D.

Probably not beta carotene, but one of the paleo boogeymen perhaps... oxalates!
