Modified Citrus Pectin

 What is modified citrus pectin?

Pectin, as it is found in the peel of various citrus fruits, is a carbohydrate that is made of thousands of sugar molecules that are chemically linked together.  Pectin in this natural form cannot be easily absorbed by the body so it is mainly considered to be a soluble dietary fiber that can be useful in pushing food through the digestive system.  In contrast, Modified Citrus Pectin has been altered so that it can be easily absorbed by the digestive tract and can travel freely through the bloodstream.

Modified citrus pectin can be helpful for detoxing heavy metals and for cancer

Modified citrus pectin has proven itself to be a useful tool in the excretion of heavy metals from the body. In a recent study, people who were given 15 grams of PectaSol-C for five days, and 20 grams on day 6. Twenty-four hour urine samples were collected on day 1 and day 6 for comparison with the baseline.  By day 6, participants excreted much higher levels of metals, for instance, arsenic excretion went up 130%, cadmium was up 150%, and lead was up 560%. Link to the study.

Modified Citrus Pectin is also proving itself to be very helpful in the prevention and treatment of metastatic cancer, this is especially true for metastatic melanoma and solid tumors such as cancer of the prostate, colon, and breast. Scientists believe that MCP works by inhibiting two key processes involved in cancer progression~ angiogenesis and metastasis.

  • Angiogenesis-  is the process in which cancer cells establish their own blood supply to fuel their growth and spread.
  • Metastasis-  occurs when cancer cells break away from the original tumor and enter the bloodstream or lymphatic system to form a new tumor in a different organ or other part of the body.  Secondary or metastatic cancers often pose more life-threatening circumstances than the original tumor.

Available evidence for modified citrus pectin:

Several animal studies found that MCP helped reduce the spread of prostate, breast, and skin cancers.  For example, one study examined the effects of MCP on lung metastases from melanoma cells.  For the study researchers injected mice with melanoma cells and then fed them differing diets. The mice that were given the MCP had significantly fewer tumors that had metastasized to the lungs than the mice that weren’t given the MCP supplement. It was also noted that if lung tumors had developed in the treated mice they tended to be smaller than those that had formed in the untreated group of rodents.

The studies also reveal that MCP makes it more difficult for cancer cells that break away from the main tumor to grow in other organs. It should be noted that in most of these animal studies, MCP had no effect on the main tumor, suggesting that it may only be a useful preventative for slowing the growth of metastatic tumors that are in the early stages of development.

Recent laboratory studies of human and animal cells have provided additional information on how MCP might slow the spread of cancer. It appear that MCP attaches to galectin-3, a common chemical that is found in many cells and is abnormally high in cancerous cells. Galectin-3 appears to play an important role in the growth, survival and spread of cancer cells. Link to this study

Another study looked at the effect of MCP on prostate-specific antigen (PSA) doubling time.  This measures how long it takes the PSA levels in the blood to increase by 100 percent.  For this test prostate cancer patients with rising PSA levels were given 6 PectaSol capsules 3 times per day for 12 months.  After treatment, 7 out of 10 patients showed a slowing of their PSA doubling time.

The U.S. Food and Drug Administration has not approved the use of MCP as a treatment for cancer or any other medical condition, but MCP is readily available in the United States as a dietary supplement.

Dosage information

Modified citrus pectin is available as a capsule or powdered form. The dose suggested by manufacturers for the powder is 5 grams (nearly a fifth of an ounce) mixed with fresh water or juice, taken 3 times a day on an empty stomach. For capsules, the suggested dose is 800 milligrams, taken 3 times a day on an empty stomach.  It is important to drink large amounts of fluids with this product.  PectaSol-C Modified Citrus Pectin is one brand that has been tested for purity and has also been used in various studies.  This product was manufactured by Dr. Isaac Eliaz, (in the video posted below).
