Extra Strength Digestive Support. Enhances Proper Digestion and Absorption of Nutrients. Plant Source. Provides Relief for Lactose Intolerance. Flora’s Advanced Adult Enzyme Blend was formulated for people seeking extra digestive support - especially individuals 65 years of age or older. This is because our ability to digest food and absorb nutrients decreases with age. This full-spectrum vegetarian enzyme blend is our most potent formula to aid in the healthy digestion of fats, proteins, soluble fiber, and carbohydrates - and it helps prevent symptoms of lactose intolerance.
