Product education

Bio-Gest®: A Comprehensive Digestive Enzyme Formula with HCl

Thorne’s Bio-Gest® is a broad-spectrum digestive enzyme supplement designed to support the optimal digestion of proteins, fats, and carbohydrates. This potent formula provides a blend of hydrochloric acid (HCl), pepsin, pancreatin, and ox bile, which are essential for individuals who experience occasional gas, bloating, and indigestion after meals. It is a particularly effective choice for those with a lifestyle that can lead to compromised digestive function, including the elderly and individuals who overuse antacids.*

How It Works: Supporting Each Phase of Digestion*

Effective digestion requires the right enzymes and acidity at each stage. Bio-Gest® is formulated to provide support throughout the entire digestive process.*

Promoting a Healthy Stomach Environment
The formula begins its work in the stomach with Betaine HCl and Pepsin. HCl is crucial for creating the acidic environment needed to break down proteins and for triggering the release of other digestive enzymes. Pepsin is the primary enzyme that begins protein digestion in the stomach. This combination is particularly beneficial for individuals who have low stomach acid.

Support for the Small Intestine
As food moves into the small intestine, Pancreatin and Ox Bile take over. Pancreatin is a comprehensive blend of amylase, lipase, and protease, which are needed to break down starches, fats, and the remainder of the proteins. In addition, Ox bile is included to aid in the emulsification and absorption of fats and fat-soluble vitamins, ensuring you get the most nutritional value from your meals.*

  • Promotes the complete digestion of proteins, fats, and carbohydrates*
  • Helps relieve occasional indigestion, gas, and bloating*
  • Provides HCl to support a healthy stomach acid level*
  • Includes pancreatin and ox bile for comprehensive enzyme support*
  • Ideal for individuals with compromised digestive function
