But this buzzy vitamin—prized for its ability to boost energy and mood—isn’t just available in pill form. Vitamin B12 injections are also gaining in popularity and availability. Curious about the benefits of B12 shots and whether they can give you a lift? About six percent of Americans under the age of 60—and 20 percent of those over 60—have a B12 deficiency (1). And while eating B12-rich foods and take oral supplements can boost your levels, vitamin B12 injections are an increasingly popular way to supplement. Vitamin B12 is responsible for making red blood cells, white blood cells, and platelets. It may also enhance the activity of certain immune cells, which may ward off viruses and chronic disease such as cancer, according to a 2020 review in the medical journal, Nature (2).For people who don’t absorb B12 well, or those whose want to make sure beyond reasonable doubt that they’re getting an ample dose quickly, B12 shots are available via prescription, says Richard Foxx, M.D., a board-certified physician who treats hormonal disorders and nutritional deficiencies.B12 ShotsVitamin B12 is a water-soluble B vitamin found in some foods. Most are animal sources (milk, egg yolks, yogurt, salmon, tuna, beef) which is why vegetarians and vegans have a higher risk of being deficient (3). B12 is also added to certain foods, like cereals.B12 injections are especially useful for people with a B12 deficiency, which tends to stem from difficulties absorbing the nutrient, not falling short nutritionally, says Foxx. People with stomach and intestinal conditions such as celiac disease and Crohn’s disease may struggle to absorb enough B12 from their food.Aging can also set you up for a B12 shortage since absorption
