Covid-19: Advice, Updates And Vaccine Options
Answer From Brent A. Bauer, M.D. Vitamin B-12 is a water-soluble B complex vitamin found naturally in a variety of foods, including meat, fish and dairy products. 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. Metformin (Fortamet, Glucophage, Riomet) is a drug sometimes used as part of a weight-loss strategy for people with type 2 diabetes. Getting large amounts of vitamin B-12 through vitamin B-12 injections isn’t likely to harm your health.
But vitamin B-12 can interfere with the effectiveness of some medications, so if you receive vitamin B-12 injections, be sure to let your doctor know. If you’re hoping to lose weight, resist the lure of quick and easy solutions. Review/update the information highlighted below and resubmit the form.
