Vitamin B12 is important for proper function the heart and circulatory system. It also promotes energy production in the body. As we age, we lose our ability to absorb B-12 from foods that we eat. Sublingual B-12 is a special formulation of B vitamins that is dissolved under the tongue, meaning that the vitamins can be absorbed directly into the blood stream. Studies have shown that this is an effective way to increase the B-12 levels in the blood. The bioavailable form of vitamin B-12 is methyl B-12. Many less expensive products use cyanocobalamin, which must be converted into methylcobalamin by the liver.
Some supplements may interact with prescription and (or) over-the-counter medicines.
