It&#8217;s found naturally in many foods, such as meat, fish and dairy products. Vitamin B-12 is added to some foods and is available as a dietary supplement. Health care providers commonly prescribe vitamin B-12 shots to help prevent or treat pernicious anemia and B-12 deficiency.<\/p>\n<p>Some researchers have studied vitamin B-12 to find out if it can raise energy and endurance during exercise. But there isn&#8217;t evidence to prove this. And unless you have low vitamin B-12 levels in your body, vitamin B-12 shots aren&#8217;t likely to give you more energy or improve your performance.<\/p>\n<p>Metformin (Fortamet, Riomet, others) is a drug that may be used as part of a weight-loss tool for people with type 2 diabetes. Low vitamin B-12 levels in your body can be a side effect of this drug. If you take metformin, talk to your health care provider about ways to keep enough vitamin B-12 in your body.<\/p>\n<p>Getting large amounts of vitamin B-12 through vitamin B-12 shots is not likely to harm your health. But vitamin B-12 may affect how well some drugs work. And some drugs can affect vitamin B-12 levels. So if you want to get vitamin B-12 shots, tell your health care provider first.<\/p>\n<p>If you&#8217;re hoping to lose weight, avoid giving in to quick and easy fixes. What counts is a healthy lifestyle. Enjoy healthier foods in proper portions. And get physical activity every day.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Vitamin B-12 injections &mdash; A weight-loss shot sounds appealing, but does it work?<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","template":"","tags":[406,1682,1113],"class_list":["post-50294","mayo","type-mayo","status-publish","hentry","tag-lifestyle","tag-person-group-concept","tag-weight-loss","content_type-answers"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.3 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Vitamin B-12 injections for weight loss: Do they work?
