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 ...

Cancer Cells Thrive on Glucose and L-Glutamine: Insights from Dr. Thomas Seyfried

Dr. Thomas Seyfried, PhD, has extensively researched how cancer cells depend on glucose and L-glutamine for their growth and proliferation. Cancer cells exhibit altered metabolism, relying heavily on glucose (the Warburg effect) and L-glutamine (an amino acid) to fuel their rapid division and growth. By disrupting these metabolic pathways, we can effectively starve cancer cells and inhibit their growth.
