Modified Citrus Pectin

Key Points
|
Pectin is a soluble plants fiber found in highest concentrations in apples and the peel and pulp of citrus fruits. Modified citrus pectin (MCP) is an altered form of citrus peel pectin that is reportedly more absorbable in the body. As a result, natural citrus pectin may not have the same effects on cancer as modified citrus pectin.1
Treatment: Impacts and Evidence
In lab, animal and preliminary human studies, MCP has shown anticancer effects in these cancers:
- Breast cancer
- Colon cancer
- Lung cancer
- Melanoma
- Prostate cancer
Clinical Evidence
MCP significantly increased prostate specific antigen doubling time in patients with recurrent prostate cancer in a small study.2
Lab and Animal Evidence
Cautions
Modified citrus pectin is “generally regarded as safe” in the US. However, MCP can cause mild side effects as well as some potentially serious interactions with drugs and supplements, including digoxin, lovastatin and tetracycline. MCP may also slow or reduce absorption of some oral drugs.7 Consult with your pharmacist for interactions, and discuss using MCP with your doctor.
Access
Pectin is found in common food sources, and modified citrus pectin is widely available in supplement form.
Non-cancer Uses of Modified Citrus PectinBCCT has not reviewed the effectiveness of this therapy for non-cancer uses.

Dosing
Although clinical trials have not established an optimal modified citrus pectin dose during or post cancer treatment, suggested dosages are listed in the integrative cancer care protocols, plans and references below. Levels of active ingredients of natural products can vary widely between and even within products. See Quality and Sources of Herbs, Supplements and Other Natural Products.
