Gallbladder Support Formulas

Blends of ox bile, beet, artichoke, dandelion and taurine sold for fat digestion. The finished formulas have never been tested; one ingredient, artichoke leaf, does have randomised evidence for indigestion.

What the science says

Artichoke leaf for functional dyspepsia Moderate evidence
A six-week multicentre randomised placebo-controlled trial in 247 patients found artichoke leaf extract improved dyspepsia symptoms compared with placebo, and a later randomised trial of a ginger-artichoke combination reported similar results. This is the strongest ingredient-level evidence in the category.
Bile salts for fat digestion Limited evidence
Ox bile and bile-salt supplements are widely sold after gallbladder removal, but there are no randomised controlled trials showing they improve fat digestion, steatorrhoea or symptoms in that population. Use rests on physiological reasoning rather than clinical data.
The blends themselves Limited evidence
No published trial has tested a commercial multi-ingredient gallbladder formula. Doses of individual herbs in these products are typically well below the amounts used in the artichoke trials.

Dosage & safety

Studied doseNo validated dose for the blends. The artichoke trials used 320-640 mg of standardised leaf extract two to three times daily. Ox bile products typically supply 100-500 mg per meal, a label dose with no trial support.

SafetyShould be avoided by anyone with a bile duct obstruction, active gallstones, or acute cholecystitis, where stimulating bile flow can trigger colic. Bile salts commonly cause diarrhoea. Artichoke is in the Asteraceae family and can cause reactions in people allergic to ragweed or daisies. Discuss with a doctor before use if you have had gallbladder surgery or liver disease.
