Enzyte is an herbal nutritional supplement originally manufactured by Berkeley Premium Nutraceuticals (now Vianda, LLC) of Cincinnati, Ohio. The manufacturer has claimed that Enzyte promotes "natural male enhancement," which is a euphemism for enhancing erectile function. However, its effectiveness has been called into doubt and the claims of the manufacturer have been under scrutiny from various state and federal organizations. Kenneth Goldberg, M.D., medical director of the Male Health Center at Baylor University, says, "It makes no sense medically. There's no way that increasing blood flow to the penis, as Enzyte claims to do, will actually increase its size."
