Modified citrus pectin (also known as citrus pectin, Pecta-Sol and MCP) is a modified, more digestible form of pectin. It is obtained from the peels, seeds and pulp of citrus fruits using a chemical extraction process.[1]

MCP is promoted in dietary supplement form as an alternative cancer treatment and is under research for its potential to increase the efficiency of a conventional chemotherapy, but there is no evidence MCP prevents or treats cancer in humans.[2] As of 2008, only three low quality studies burdened with conflicts of interest had been published about its potential as a chelating agent.[3]

Toxicity and side effects[edit]

Although modified citrus pectin is more easily digested than natural citrus pectin, individuals with allergies or sensitivities to citrus may experience diarrhea or stomach discomfort when taking either type of citrus pectin.[2]

In general, pectins are considered as safe ingredients used over decades for emulsifying manufactured foods; accordingly, pectin and MCP are considered GRAS by the US Food and Drug Administration.[1]
