Betaine and Pepsin is designed for those who want a digestion aid, as the potency and volume of gastic juice can be reduced with age. This makes it difficult to digest foods after a meal. This formula can also help anyone seeking enhanced digestive function. Betaine HCl is an acidic form of betain used to lower stomach acid pH. Pepsin is an enzyme produced naturally in the stomach to aid in the digestion of proteins. Usual dose is 1-2 capsules before each meal, or as directed by your physician.
