B12 Injections refer to shots that deliver a high dose of vitamin B12 directly into the body. Vitamin B12, also known as cobalamin, is essential for many critical functions in the body, including energy production, DNA synthesis, and the formation of red blood cells. While vitamin B12 is naturally found in animal products, certain populations, such as vegetarians, vegans, and some elderly individuals, might not get enough from their diets. Others may have absorption issues, such as those with pernicious anemia or certain gastrointestinal disorders, which prevent them from absorbing B12 effectively from food. In these cases, B12 injections can help restore optimal levels. B12 injections are typically administered intramuscularly, often into the upper arm or hip. Before starting B12 injections, it’s important to discuss potential benefits, side effects, and the frequency of administration with a healthcare provider.
