Vitamin B12, also known as cobalamin, is a water-soluble vitamin that is naturally found in animal products, including meat, fish, and dairy products, and it is also available as a dietary supplement, an injectable (commonly known as vitamin B12 shots), and in fortified foods

While B12 plays a role in cellular energy metabolism, supplementing B12 in a patient who is not deficient does not increase metabolic rate or cause fat loss

Early signs include tingling or 'pins and needles' in the feet and hands, numbness in the extremities, burning pain (often worse at night), balance problems, and muscle weakness

While some patients notice improvement after a single session, most people require a series of treatments to achieve their desired results

Additional testing should include fasting glucose or hemoglobin A1c, lipid panel, complete blood count, and thyroid function
