B2 is vital for protein and carbohydrate metabolism.  Riboflavin is a precursor to two coenzymes. Coenzymes are molecules that carry chemical compounds between two enzymes which transport many substances in the body. Being a precursor simply means that the equine body uses B2 to make the coenzymes. B also appears to have a role in fat metabolism.

There is a specific site in an area of the small intestine where dietary B is absorbed.  It binds to a carrier protein and then is transported to the liver, the adrenals, and other sites where it is built into the enzymes.

As with all water soluble vitamins excess B is withdrawn by the kidneys and excreted via the urine.
