Understanding what Modified Citrus Pectin (MCP) Pectasol-C® is, how it interacts with galectin‑3 and cancer, what the research shows, and what patients should know about safety, interactions, and integrative oncology considerations.

What Is Modified Citrus Pectin?

Modified citrus pectin (MCP), Pectasol-C, is a form of pectin derived from the peel and pulp of citrus fruits. Unlike regular pectin—which is too large to be absorbed—MCP is processed into smaller, low‑molecular‑weight fragments that the body can absorb more easily.

MCP is rich in galactoside residues, which give it a unique ability to bind to certain proteins involved in cancer biology, especially galectin‑3.

Pectasol-C® is a brand of MCP. 

How MCP May Influence Cancer Biology

Much of MCP’s anticancer interest comes from its ability to bind and block galectin‑3, a protein involved in:

• Tumor growth[i]
• cell adhesion
• metastasis[ii]
• angiogenesis
• immune evasion
• apoptosis resistance

Galectin‑3 is overexpressed ...

How pumpkin seeds support anticancer nutrition, key nutrients, research findings, and practical guidance. 

Research and written by Keith Bishop, Cancer Coach, Clinical Nutritionist, Retired Pharmacist, and Founder of Prevail Over Cancer™ and the Prevail Protocol™

Pumpkin seeds—often treated as a simple snack—are quietly becoming one of the most compelling foods in anticancer nutrition. Rich in bioactive compounds, antioxidants, lignans, and unique proteins, these seeds have demonstrated promising effects in laboratory studies and population research. Below is a comprehensive, evidence-based look at what we know so far.

Anticancer Actions of Pumpkin Seeds

Pumpkin Seed Apoptosis-Inducing Activity

Pumpkin seed protein fractions have been shown to induce apoptosis (programmed cell death) in cancer cells, including liver (HepG2) and triple-negative breast cancer (MDA-MB-231) cell lines.[i]

Antioxidant & Anti-Inflammatory Effects

Pumpkin seeds contain phenolic compounds, tocopherol...
