I was wondering if anyone who has been injecting B12 has run into any issues with blood sugar. My fasting glucose has always been normal but recently it has spiked to 112. I just had a hemoglobin a1c which came back high at 6.1 (reference range is topped at 5.7). After doing some reading it appears that among many other things, B12 apparently also held the body produce glucose. My mother in law just informed me that she read an article that stated 1-2 years of high B12 levels can raise sugar. I've been injecting and supplementing with sublinguals for a year and a half and try to keep my B12 from. Dropping below 700. Any info would be helpful, thanks in advance!!!
