Some weight-loss clinics offer vitamin B-12 injections as part of their weight-loss programs. Proponents of vitamin B-12 injections say the shots give you more energy and boost your metabolism, helping you shed unwanted pounds. But unless you have a vitamin B-12 deficiency, vitamin B-12 injections aren’t likely to give you an energy boost.
Although getting B-12 injections may not harm your health, vitamin B-12 may interfere with the effectiveness of some medications. If you are considering getting injections or taking oral supplements, please talk to your doctor first.
