Now Acid Relief with Enzymes supports the relief of occasional acid indigestion and upset stomach. Calcium Carbonate for relief of occasional heartburn has been well accepted, and works by neutralizing the acid produced in the stomach. It can however, slow down the digestion of food when used alone because the enzymes secreted by the stomach only work at acidic pH. Acid Relief with Enzymes combines Calcium Carbonate with digestive enzymes to encourage complete digestion of food, even in the presence of reduced stomach acid. This formula delivers rapid relief from occasional indigestion, as well as digestive enzymes in a delicious chewable tablet. Natural color variation may occur in this product. Recommended Use: Chew 1-2 tablets daily as needed, or as directed by a healthcare professional. Store in a cool, dry place after opening. Warning: Xylitol is harmful to pets; seek veterinary care immediately if ingestion is suspected.
