B12 shots are intramuscular injections of vitamin B12, a crucial vitamin that supports various bodily functions, including energy production, metabolism, and cognitive health. Vitamin B12 is naturally found in animal products, but many people have difficulty absorbing enough from their diet alone, leading to fatigue, weakness, or even mood disturbances. B12 injections bypass the digestive system, delivering the vitamin directly into your bloodstream for faster, more effective absorption. This makes B12 shots a great option for those looking to improve their energy levels, support healthy metabolism, or boost overall wellness.
