I have recently be prescribed Cyancobalamin 50 mcg tabs 3 times a day by GP after my b12 level was checked and described as low. The GP suggested this may be caused by poor B12 absorption in my GI tract. My symptoms mainly are Paresthesia in my fingertips and soles of my feet. I am wondering how tablet form of B12 will be absorbed any better as so far I have had no improvement. Would injections be better??
