B12 Side effects

[LONGEATON]

At my last blood take the Serum & Folate B12 reading was 278 ng/L and have been prescribed Cyanoco B12 100mcg tablets one per day

Since taking B12 my skin has been alive with irritation, in particular my back - is this usual?

With serum B12 result below 500, (Or active B12 below 70) recommended to be taking a separate B12 supplement

A week later add a separate vitamin B Complex 

Then once your serum B12 is over 500 (or Active B12 level has reached 70), you may be able to reduce then stop the B12 and just carry on with the B Complex.

supplementing a good quality daily vitamin B complex, one with folate in (not folic acid) .This can help keep all B vitamins in balance and will help improve B12 levels too

Thorne Basic B recommended vitamin B complex that contains folate, but they are large capsules. (You can tip powder out if can’t swallow capsule) Thorne can be difficult to find at reasonable price, should be around £20-£25. iherb.com often have in stock. Or try ebay

IMPORTANT......If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 7 days before ALL BLOOD TESTS , as biotin can falsely affect test results

In week before blood test, when you stop vitamin B complex, you might want to consider taking a separate folate supplement (eg Jarrow methyl folate 400mcg) and continue separate B12
