Digestive Health & Function

Fiber supplements (psyllium, methylcellulose, inulin, pectin and others) add bulk and water to stool. They are a first-line option for constipation and hemorrhoids, and soluble types modestly improve cholesterol and blood sugar.

Electrolyte drinks, powders and tablets supply sodium, potassium and chloride (often with glucose) to replace what is lost in sweat, vomiting or diarrhea. Their best-proven use is oral rehydration solution for dehydration; for everyday hydration, water and food usually suffice.

Glutamine is the most abundant amino acid in the body, essential for gut health, immune function, and muscle recovery. It supports intestinal barrier integrity.

Licorice root with glycyrrhizin removed to eliminate aldosterone effects while preserving digestive benefits. Supports stomach and intestinal lining, promotes healing, and reduces inflammation.

Dried or fresh seeds of the papaya fruit, a traditional dewormer. Two small trials in children with intestinal worms were positive, but the evidence is thin and animal data raise fertility concerns.

Digestive enzymes break down proteins, carbohydrates, and fats, supporting nutrient absorption and reducing digestive discomfort.

Probiotics are live microorganisms that provide health benefits when consumed in adequate amounts. These beneficial bacteria support digestive health, immune function, and may influence mood and cognitive function through the gut-brain axis.

A carvacrol-rich essential oil distilled from oregano. Strong antimicrobial activity in the lab, but only small, early human trials so far.

An edible red seaweed, also called Irish moss, sold dried or as a gel. It supplies carrageenan and some minerals, but no human trial has tested its health claims.
