Di-Acid Stim from Bio-Design®


Hydrochloric Acid and Digestive Enzymes

Bio-Design’s Di-Acid Stim provides digestive support in a unique (or, at least, uncommon) two-phase delivery system: Phase I, in the stomach, and Phase II, in the duodenum, making it an excellent two-phase release aid for proper food digestion.

120 tablets bottle.

Bio-Design’s Di-Acid Stim offers excellent support for those who need added HCl and pepsin, as well as digestive enzymes, for the proper digestion of foods.  I’ve used it for years, and have found it quite helpful.

The enzyme ingredients in all of Bio-Design’s enzyme products are made fresh with each batch in order to ensure the highest enzymatic activity levels.

  • Supports Healthy Digestive Function
  • Two-Phase Release Tablet

Bio-Design’s DiAcid Stim is a unique, comprehensive hydrochloric acid (HCl) and digestive enzyme formula, supplied in a single, convenient two-phase release tablet. DiAcid Stim can be particularly beneficial for people as they age, due to both diminishing stomach acid and diminishing digestive enzyme levels, which result in indigestion, gas, bloating and reduced utilization of nutrients.

Most digestive formulas support only one phase of digestion, providing either digestive enzymes or hydrochloric acid. Because DiAcid Stim provides both.  It can assist those with low stomach acid, by supplying the hydrochloric acid (HCl) and pepsin, necessary for the stomach phase of digestion. Additionally, it supplies digestive enzymes for intestinal digestion.  Bio-Design’s two-phase release tablet is designed to release Betaine HCl and glutamic HCL in the stomach, while delaying and protecting the digestive enzymes from acid until they reach the intestine.


The ingredients of HCl, Pepsin and digestive enzymes combine to provide an optimum breakdown of food, so absorption of vitamins and minerals can be enhanced.

  • Phase I: 220 mg Betaine HCl, 220 mg Glutamic Acid HCl, 100 mg Pepsin, 50 mg Papain.
  • Phase II: 100 mg Pancreatin, 30 mg Amylase, 40 mg Bromelain.


Suggested Use: As a dietary supplement, take 3 capsule daily, with meals, or as directed by your healthcare practitioner.
