Digestive enzymes are essential to the body's absorption and full use of food. The capacity of the body to make enzymes diminishes with age, and therefore the efficiency of digestion declines. Now Optimal Digestive System features a blend of non-GMO, fungal-derived enzymes that may aid in digestion. The vegetarian enzymes in Now Optimal Digestive System have been proven in a controlled laboratory study by the Netherlands Organization for Applied Scientific Research (TNO Nutrition and Foods Research) for active enzyme activity throughout the entire pH range of the digestive system.
