Too much B12

8 Replies

Hi, can anyone tell me if spots on the face and neck are a symptom of too much B12. I supplement with jarrows 1000. I have been taking them for a few years but lately find I am having break outs of spots, something I have never suffered with. I also take a Vit D supplement so could be this as we have had such lovely weather maybe I don’t need the supplement. Thanks,

All's I can say about myself is that in the beginning when I had loading doses of IM B12 and then monthly for a good while, I had spots on my face neck and on my head amongst my hair. Apparently it's the b12 lowering the toxic homocysteine levels and it can come out as zits on your skin. So it's a good sign. My skin cleared once my b12 level got up to 2000 and my homocysteine levels returned to normal.

I would agree with this. I started taking high dose B12 and developed lots of spots, but I persevered and my spots eventually went away. My skin ended up looking better and being less spotty than it was before I started the B12. If I let my B12 drop a bit I'll get spots on the way down and spots when I go back to taking B12 again (at least until my level has returned to "normal for me"). My levels of B12 are often greater than 2000.

Thanks for your help. I think I will get my B12 and Vit D tested and if they are ok put the spots down to something that will go. Just wondering if anyone could recomend a good Magnesium supplement to take.

Hi, a person only has about 20% of the total serum B12, that's active as it's a mix of active and inactive. Once you're on b12 , as in my case for life, there's no point in measuring it,. Measuring the b12 is only good for diagnosis in beginning. Body only takes what it needs and excretes the rest in urine. Non toxic. It lowers toxic homesysteine levels which cause , strokes and heart attacks , nerve damage from demyelination of myelin sheaths and brain shrinkage that can mimic dementia. B12 is a holy grail. It can only do good and every granny and grandpa especially should be on it to keep them out the nursing home supposedly suffering from dementia.

If your spots are related ( and you don't know) dont stop taking it all the same as soon as the homesysteine levels are normal, your skin will be glowing with good health. All the best

Thanks for that, I will stick with the B12 and hopefully the spots will clear up.

Spots on the face an be a symptom of mask-wearing, if you haven't been changing the mask every couple of hours or when damp, or haven't been washing your hands every time you touch the mask. I'd think it would only affect the neck if you pull the mask down under your chin or touch your neck after touching the mask. I take large doses of B12 (Jarrow 5000) and haven't had spots.

Apparently not, although my Dad did. Some people on HU think I might have in spite of negative test
