I listened to Dr Jess w/ her talk on reviewing. her labs and she discussed getting IV- B vitamins really helped. I have MTHFR and have been taking injectable Methylcobalamin 25 MG on the side of my butt cheek & also MIC w/ HB12 1ML in the butt cheek muscle as well. Does the injectable that I’m doing in my butt cheek benefit as well as the IV in the vein for the B 12 vitamins is what I wanted to. know? Thank You
