B12 side effects? Or?

Hi everyone I’ve been taking b12 1110mcg daily since July. I’m currently trying to work out the cause of my more of less daily headaches / fuzzy head. I know these can just be ms general symptoms, but thought I’d look at what I take. As I take 4000iu vit D, 1000mg flax seed oil and 1110mcg B12 daily with breakfast, but by 12pm I have a headache/dizzy just generally feeling off creeping in by mid day. I’m thinking perhaps B12 is too high? I originally started it due to its help with myelin sheeth repair etc.

Just wanted to see what dose b12 everyone else is on? What the daily maintenance recommendation was.

I’m also due an ocrevus dose but cd19 still testing at zero so It’s delayed 6 weeks for re test. Perhaps it’s related to being due more ocrevus? But I’m testing zero so not sure it’s that.

Many thanks

This is general information from the NHS concerning B12. Obviously, it doesn’t take into account your specific circumstances and who suggested you take that amount.
Regarding headache, are you drinking enough water?

" How much vitamin B12 do I need?

Adults (aged 19 to 64) need about 1.5 micrograms a day of vitamin B12."

I have been having 12-weekly B12 injections from the nurse for donkey’s years. No idea if the dose, I’m afraid. I was told that you just pee out anything you don’t need, and so there are really no downsides and that I should therefore keep having them even though I have no idea whether they’re still needed or doing much good.

You could try dropping all three (B12, oil and vit D) for a few days to see if that makes a difference, and then add back in one at a time, with a few days between, to see if any cause the symptoms to flair up.

Thanks everyone, I’ve dropped all tablets and reintroduced the Vit d and magnesium and so far so good. So perhaps it was the high dose of b12!?! Fingers crossed
