I have been having the pin pricking sensation which you HU folk say is a side effect of low B12, but I am taking a sublingual B12 supplement of 1,000ug by a company called Nu U Nutrition, for a month now and still have the pricking sensation.
So I'm wondering whether these tablets are a good enough quality. I think they are a fairly new company and only sell on Amazon.
Would love some answers please from you very knowledgeable people ? Getting really fed up with sensation !!
