Can B12 cause migraines?

I started taking a multi-vitamin and a 500mcg B12 supplement as part of my weightloss plan. I've been having evening left side migraines every night since. I did not take the B12 today out of suspicion that it could be causing them and so far tonight I am okay. Has anyone else had headaches or migraines after taking B12 supplements?

    No, but my sister gets horrible nightmares when she takes B. If you think it's causing the migraines, just stop taking them. It's not worth it.

    Whoa. I take B complex all the the time and also get horrible headaches. NEVER connected them. Do you think it's only B12 or could it be other B's too?

    B12 deficiency can cause migraines... should be getting the reverse situation. Maybe it's something else in the multiviamin??

    I've been taking B12 & also get headaches but never connected it. I'm not going to take them this week & test this theory.

    Migraines have been connected to a *deficiency* of B12 in articles I've read, but I don't recall seeing anything about it causing them. Doesn't mean it isn't possible, that's for sure. Every body is different.

    What?

    It's just a way to bring it back to the top for you.

    I get sick from iron but don't recall any headaches from multis or when I took B6. I really should take B12 as I don't always get enough in.

    Thanks. I had just googled it lol. I don't belong to many forums so this is the first time I've seen "bump" :)

    I have b12 deficiency and I got really bad headaches, migraines, and extreme fatigue. Since I started taking b12 shots the headaches and migranes have gone away.

    I take tons of B vitamins without issue. I do however get nasty headaches if I don't drink lots of water. Quitting something like caffeine also throws me for a headache loop for a few days.

    holy cow! i've never even heard of this case. I started taking b12 last september as it's hard to get b12 on a vegan diet and the only thing i've noticed is improved energy and overall happiness. when i don't take them sometimes i get grumpy, and research has linked b12 deficiency to that.
    just thought i'd put in my two cents to not totally deter anyone from ever taking b12 as i love it and it's done wonders for me.

    So, I tested this theory by going without my B12 vitamin for a few days. I still got headaches plus I feel tired & run down so I'm going to start back on them tommorow.

    I never connected the two, but recently have been getting horrible migraines after I have religiously been taking B12 and B6.

    Since you're taking B12, I'm assuming your a vegetarian/vegan. I used to eat a lot of soy products (occasional fake meats, soy milk, protein bars, etc.) and I had massive migraines for a year and no matter what I did, I couldn't rid of them.

    One day, I did a little reading and found that soy may cause migraines in people. When I gave up the soy, the migraines went away. If I start eating too much again, they come back. I also take B12 and have never had a headache by it.

    So maybe it's something else in your diet? Also, since your body stores B12, you could probably skip a few days between each dose, but I'm not a doctor. :)

    I hope you get this figured out, cause migraines are terrible to live with.
