I am 18 months post op from RNY surgery. The first year I took my B12 shots once per month, but then I switched over to sublingual B12 once per day. During my visit with the nutritionist last week, she asked me what type of sublingual B12 I was taking. Apparently there are two types. The correct type is called methylcobalamin and it turns out that was the type I had been taking. So is this commonly understood? What type are you taking?

I was told to use the one from Celebrate Vitamins which is what I do.
