Enzymes levels decline with age. Low enzyme levels are correlated with advancing age. Each decade (after what age?), the body’s production of enzymes decreases by about 13%. In addition, your stomach also produces less hydrochloric acid (HCl) which is critical in activating your stomach’s digestive enzymes. Betaine hydrochloride can be taken as a supplement. Poor enzyme and HCl levels reduces nutrient absorption which can lead to illness and disease.
