What are B12 Shots?


B12 shots are a type of vitamin B12 supplement. They usually come in the form of an injection, which you can self-administer or have done by a healthcare professional.

Vitamin B12 is an essential nutrient that helps keep your nervous system functioning properly. It also aids in the production of red blood cells and DNA. A lack of vitamin B12 can lead to fatigue, weakness, and memory problems.

B12 shots are often recommended for people who don’t get enough vitamin B12 in their diet. This may be due to a vegetarian or vegan diet, poor absorption from the gut, or certain medical conditions such as Crohn’s disease.

B12 shots are also used to achieve weight loss. While there is no conclusive evidence that they help with weight loss specifically, vitamin B12 is involved in energy metabolism and it is possible that getting more of this nutrient could help boost your metabolism and get you to a more healthy weight.


If you’re considering trying a vitamin B12 shot for weight loss, talk to your doctor first to see if it’s right for you.
