Vitamin U is A vitamin found in green vegetables. It is used in the treatment of peptic ulcers, colitis, and gastritis and has an effect on secretory, acid-forming, and enzymatic functions of the intestinal tract.The Vitamin U was termd from the fact that a very small quantity of this compound was effective for the medical treatment of the gastric ulcer.
