Beneficial "good" intestinal bacteria promote health, discourage the growth of disease-causing "bad" bacteria and pathogenic fungi, and improve the balance of microbes which normally inhabit our intestines. Many beneficial bacteria transform naturally occurring sugars, especially lactose, into lactic acid, promoting a more balanced and stable intestinal environment. As one of the most abundant sources of lactose is milk, these beneficial bacteria have been used for thousands of years to produce yogurt, cheese, and fermented milks. Both science and folklore support healthful roles for these foods. GNLD's supplement of beneficial bacteria, Acidophilus Plus, combines potency with technology to guarantee that live organisms survive the stomach acid and reach the intestines to deliver five billion viable organisms capable of supporting optimal digestive tract function.
