how soon will i feel the effects of b12 injections Are Vitamin Shots Right for You? How Long Does It Take
Description
Patients with severe, longstanding deficiency typically require longer recovery periods, with haematological improvement occurring over weeks and neurological recovery potentially taking months

Side effects are rare and usually mild, such as slight soreness at the injection site

This is not a health side effect per se, but it is a consequence of use that certain populations must consider

Injections work faster and are better for people who cant absorb B12 well
