What is it?

These entries are from the Memorial Sloan-Kettering Cancer Center website. Last updated: July 2013.


Pectin is a soluble fiber present in most plants but is concentrated in the peel and pulp of citrus fruits (lemons, oranges, grapefruits) and apples. Modified Citrus Pectin (MCP) is obtained by changing pectin so it is better absorbed by the body. Data from studies in cells and mice showed that pectin and MCP have anticancer properties. There is also some evidence from human studies that pectin and MCP are effective in treating diarrhea and in lowering cholesterol. Pectin causes side effects such as abdominal cramps and diarrhea.

Does it work?

Laboratory and animal studies have shown that pectin has anticancer properties. Human studies are needed to verify these results.

Is it safe?

Do Not Take If
  • You are taking lovastatin for high cholesterol because pectin may inhibit the action of lovastatin and may increase LDL cholesterol.
  • You are taking carotenoid and alpha-tocopherol supplements because pectin interferes with their absorption.
