Are B12 injections for life?
If your vitamin B12 deficiency is not caused by a lack of vitamin B12 in your diet, you’ll usually need to have an injection of hydroxocobalamin every 2 to 3 months for the rest of your life.
When are B12 injections necessary?
Vitamin B12, found in any food from animals, needs to be released from proteins during digestion. If the stomach does not produce enough acid, the body does not absorb B12 from food very well, but it can still easily absorb the B12 in an oral supplement. For some people, taking B12 as a muscle injection is necessary.
Is there an alternative to vitamin B12 injections?
Oral vitamin B12 replacement at 1000 μg daily is an adequate alternative to IM B12 injections. Close monitoring with clinical review and repeat vitamin B12 levels are required on a monthly basis to review symptoms and ensure normalization of B12 deficiency.
Where does B12 originally come from?
B12 is the only nutrient in the human diet that simply must come from animal products. The best source of B12 is meat, including both red and white meat, fish, and seafood. Eggs and milk have some B12 as well. Plants and fungi, however, have no need for B12 and therefore do not contain any of it.

Can you overdose on B12?
Since B12 is a water-soluble vitamin, it’s generally considered safe, even at high doses. No Tolerable Upper Intake Level (UL) has been established for B12, due to its low level of toxicity. UL refers to the maximum daily dose of a vitamin unlikely to cause adverse side effects in the general population.
Do you need a prescription for B12 shot?
A B12 shot contains high levels of cyanocobalamin, which quickly elevates B12 levels in the body. Injections are water-soluble, which helps your body store and use the vitamin as it’s needed. Shots can be self-administered or given by a doctor. You need a prescription for injections.

What form of B12 is best?
The body may absorb cyanocobalamin better, while methylcobalamin has a higher retention rate. Both can prevent B12 deficiency, but methylcobalamin should be combined with adenosylcobalamin for best results.
