Vitamin B12, also known as cobalamin, is a water-soluble vitamin essential for various bodily functions, including nerve function, DNA synthesis, and the formation of red blood cells. It naturally occurs in animal-based foods like meat, fish, poultry, eggs, and dairy products. Vegans and vegetarians often require supplementation since B12 is not naturally found in plant-based foods. It is also added to some foods like fortified cereals and nutritional yeasts.
Vitamin B12 supplements are widely available from various manufacturers and retailers. Some popular brands include Nature Made, Thorne, Garden of Life, and GNC. These supplements come in various forms, including tablets, softgels, gummies, liquids, sublingual tablets, and even injections. The most common form of B12 in supplements is cyanocobalamin, but other forms like methylcobalamin, adenosylcobalamin, and hydroxycobalamin are also available. The price of B12 supplements generally ranges from $0.10 to $1.00 per serving, or $7 to $30 per container. The appropriate dosage varies depending on individual needs, with supplements typically containing between 500 to 2,000 mcg per tablet. Vitamin B12 supplements are readily available online and in stores like Walgreens, Walmart, Target, and GNC.
