Di-Acid Stim

120 tablets



Di-Acid Stim is a unique, comprehensive Hydrochloric acid (HCL) and digestive enzyme support formula supplied in a single convenient two phase release tablet. Di-Acid Stim can be particularly beneficial for people as they age, due to diminishing stomach acid and digestive enzymes which result in indigestion, gas, bloating and reduced utilization of nutrients.


Most digestive formulas support only one phase of digestion, providing either digestive enzyme support or hydrochloric acid. Di-Acid Stim provides both. It assists those with low stomach acid by supplying Hydrochloric acid (HCL) and pepsin necessary for the stomach phase, and it supplies additional digestive enzymes for intestinal digestion. Because stomach acid can damage sensitive digestive enzymes when HCL and enzymes are taken together, our two phase tablet is designed to release HCL in the stomach while delaying and protecting the digestive enzymes until they reach the intestine.*

Try Di-Acid Stim, we are confident you will feel the difference!


*Our Supplement Facts for Di-Acid Stim has been updated to show the activity levels of the digestive enzymes. At Bio-Design, transparency of our products is of the utmost importance to us. The milligram amount of an enzyme does very little to tell you have effective it is. That’s why we are changing the amount per serving in our Supplement Facts to reflect the units of digestive activity.
