Digestive Aid

180 Capsules ( SKU: 9502, NPN: 80074759 ), 90 Capsules ( SKU: 9504, NPN: 80074759 )


  • Broad-spectrum digestive formula designed to enhance carbohydrate, protein, and lipid absorption
  • Provides a clinical dose of HCl and a complex of betaine and L-glutamic acid to restore optimal gastric pH in less than 10 minutes
  • Provides pancreatic enzymes containing protease, amylase, and lipase for broad-spectrum macronutrient digestion
  • Contains pepsin A that acts as a principal protease and key signal for optimal digestion
  • Ox bile promotes effective lipid and protein digestion and targets metabolic function and intestinal flora composition

Feature Summary

BioDigest provides a comprehensive formula designed to enhance the digestion and absorption of carbohydrates, proteins, lipids, and micronutrients. A decline in acid production is associated with several conditions as well as the normal aging process. This decline may impair the absorption of several micronutrients (including zinc, iron, and vitamin B12) and contribute to bacterial overgrowth in the intestinal tract.1,2,3 The use of hydrochloric acid complexed with betaine and glutamic acid has been shown to normalize gastric pH among participants with impaired acid production, achieving a pH of less than 3 in under 10 minutes and lasting over 70 minutes. This pH normalization effectively improves the absorption of substances dependent upon low gastric pH.4,5

BioDigest also provides pancreatic enzymes designed to restore normal digestion to patients with impaired exocrine pancreatic function, with protease, amylase, and lipase activity for digestion of all macronutrients. The inclusion of ox bile promotes efficient lipid absorption as well as enhanced proteolysis of dietary protein.6 Additionally, bile acids upregulate brown adipose tissue activity, have antimicrobial activity in the small intestine, and have systemic metabolic and endocrine effects previously unrecognized, influencing thyroid function, metabolism, and glucose and lipid homeostasis.7–10 Finally, pepsin A is the principal gastric proteolytic enzyme, and its actions indirectly stimulate pro-digestive functions by triggering gastrin and CCK release.11

Recommended Adult Dose: 1 capsule 4 times per day with or immediately before food, a few hours before or after taking other medications, or as directed by a health care practitioner. Consult a health care practitioner for use beyond 7 days. Use the smallest effective dose that controls your symptoms.


Consult a health care practitioner if symptoms persist or worsen. Consult a health care practitioner prior to use if you have faecal impaction or symptoms such as abdominal pain, nausea, vomiting, or fever, if you have a peptic ulcer, excess stomach acid, high cholesterol, diabetes, pancreatitis, pancreatic exocrine insufficiency, cystic fibrosis, gastrointestinal lesions/ulcers, if you are taking blood thinners or anti-inflammatory agents, are having surgery, or are taking thiazide diuretics, corticosteroids, licorice root, or other medications or health products which may aggravate electrolyte imbalance. Do not use if you are pregnant or breastfeeding, are sensitive to pancreatic enzymes or pork proteins, have gallstones, bile duct obstruction, abnormal constrictions of the gastrointestinal tract, potential or existing intestinal blockage, atonic bowel, appendicitis, inflammatory colon disease, such as Crohn’s disease or ulcerative colitis, abdominal pain of unknown origin, undiagnosed rectal bleeding, severe dehydration with depleted water or electrolytes, or diarrhea. Laxative effect may occur. Stop use and consult a health care practitioner if hypersensitivity/allergy, nausea, vomiting, abdominal pain, epigastric pain, cramps, spasms, diarrhea, and/or heartburn occur. Keep out of reach of children.


Contains no artificial colours, preservatives, or sweeteners; no dairy, sugar, wheat, gluten, yeast, soy, egg, fish, shellfish, salt, tree nuts, or GMOs. Sealed for your protection. Do not use if seal is broken. For freshness, store in a cool, dry place.


Safety during pregnancy and lactation has not been established, and should be avoided. Individuals with a
sensitivity or allergy to pancreatic enzymes or pork products should avoid using. Should be used with caution in an individual with a history of a peptic or duodenal ulcer or inflammatory bowel disease, and avoided in those with intestinal obstructions, atonic bowel, abdominal pain of unknown origin, undiagnosed rectal bleeding, severe dehydration or diarrhea.
