Hi All, I was actually tested to be low in B12, which means I am probably VERY low by this point. I have been following Freddd's MB12+ADB12+Metafolin plan religiously for a few weeks now. I've been feeling better and better. I take a single Enzymatic Therapy 1mg B12 each morning. I know Freddd recommended the 5mg Jarrow in the past, but no longer. So I just take the single 1mg. I've read that some people experience pink urine from injected MB12, and some people even with sublingual. I'm wondering if this is a good thing, that you've titrated up to as much as your body can hold and you're getting rid of excess. Since, I've never experienced this, I wonder if I should be adding more ET 1mg a day up until I reach "urine tolerance" and keep it right before that level until I saturate my body. Or, is the urine thing just a side effect with people who have kidney issues or just not absorbing it well in the first place? Or, does this only happen with injected MB12, and sublingual will never go to pink urine?
