Apple Pectin

A gel-forming soluble fiber from apples. Pectin lowers LDL cholesterol modestly at doses far higher than most capsules provide, and its effects on stool form are barely studied.

Evidence last reviewed: August 2026

What the science says

  • LDL cholesterol Moderate evidence

    A classic meta-analysis of dietary fiber trials found that pectin lowered total and LDL cholesterol by a small amount, on the order of a few percent, at intakes of several grams per day. A controlled human study of isolated fiber components reached the same modest conclusion.

  • Apple products and cardiometabolic markers Limited evidence

    A systematic review and meta-analysis of randomized trials of apples and apple-derived products reported small metabolic and cardiovascular improvements, but the trials tested whole apples and juices rather than pectin capsules.

  • Stool form and regularity Limited evidence

    Pectin is a gel-forming fiber and is often marketed for stool normalization, but there are no adequately sized randomized trials of apple pectin supplements for constipation or diarrhea in adults.

Dosage & safety

Studied doseCholesterol trials used roughly 6–15 g of pectin per day. Typical capsules provide only 500–1,000 mg, far below the studied dose.
SafetyGenerally safe; gas, bloating and cramping at higher doses. Being viscous, it can slow the absorption of medications and minerals — space it a couple of hours apart, and take with plenty of fluid.
