For most people with straightforward B12 deficiency due to dietary insufficiency , oral cyanocobalamin at doses of 50-150 micrograms daily between meals is the standard UK recommendation
Some groups are more likely to come up short, including older adults, people who eat little or no animal food, and those with digestive conditions that make absorption harder
You should have your vial of vitamin B12, a sterile syringe, two needles (one for drawing the vitamin and one for injecting), alcohol wipes, and clean gauze or a cotton ball
Healthcare professionals prescribe B12 injections for people with a nutrient deficiency
