b12 injection for cancer patients Cyanocobalamin Vitamin 1000 mcg — Mountainside Medical Vitamin B12 Injection - 10mL
Description
Multivitamins are intended to supplement your diet and should not be regarded as a substitute for a varied diet and a healthy lifestyle

The family of B vitamins is composed of three compounds: B1, B6, and B12

Foods like meat, fish, dairy, and eggs are primary sources of B12

I think they should take the blood test before they give the injection and maybe that would give a truer reading
