Vitamin B12 Benefits: Boosting Health & Vitality Naturally

My B12 levels get very low, but because of cobalt sensitivity, I break out in an extremely itchy rash when I take it. It happens when I get injections and when I take over the counter supplements. I have an oral spray, a B complex, B12 alone, even multivitamin, they all cause me to break out in a rash? Anyone else have and even solve this dilemma? I sure could use some advice.
