Vitamin B12

Vitamin B12 is a water-soluble B vitamin. B12 is also known as cobalamin because it contains cobalt. The form of B12 most commonly used in dietary supplements is called cyanocobalamin. B12 is only produced by bacteria, so it is only found in food products of animal origin and in some fermented vegetable products such as tempeh and miso (fermented soybeans)
