Grapefruit pectin is the white substance in the rind of a grapefruit. Pectin is a soluble fiber that has a specific action in your intestinal tract. According to a 2004 issue of "Life Extension," when manufacturers chop grapefruit pectin into very small pieces, it changes the structure enough that it becomes more absorbable. This slight modification of pectin's structure allows your body to absorb it directly into your bloodstream, which can help improve your cardiovascular health. However, consult with your health-care provider prior to using grapefruit pectin for high blood pressure.
History
Historically pectin has been used in the food industry as a gelling agent and thickener for jellies and canned foods. In addition to being used as a food product, it has been added to some anti-diarrhea medications and in certain cosmetics. More recently -- over the past 10 to 15 years -- laboratory studies of animal and human cells have indicated that citrus pectin, including grapefruit pectin, may have health-promoting and cancer-fighting properties. However, large randomized controlled human studies are needed before any firm conclusions regarding benefits to people can be reached.
Effects
Grapefruit pectin may help reduce cholesterol levels, which may improve your cardiovascular health and reduce your high blood pressure. A study published in a 1988 issue of "Clinical Cardiology" reported the effects of grapefruit pectin on humans at risk for heart disease without altering their current diet. After the study participants had gone through 16 weeks of treatment, the researchers from the University of Florida College of Medicine found that grapefruit pectin reduced overall cholesterol levels by 7 percent and low-density lipoprotein, or LDL, levels by as much as 10 percent. The researchers concluded that grapefruit pectin may help reduce blood cholesterol levels, which might help lower cholesterol-induced high blood pressure.
Preparation
Your body most easily absorbs grapefruit pectin when it has been broken down into very small molecules. Therefore, look for a product that states that it is a modified citrus pectin. According to "Thai Science," in order to experience a significant reduction in blood cholesterol and, therefore, lower your blood pressure, take at least 6 grams of grapefruit pectin per day. You can find grapefruit pectin at your local health food or supplement store in powder, capsule or tablet form. Consult with your doctor prior to using a grapefruit pectin supplement for high blood pressure.
Side Effects
According to the American Cancer Society, the U.S. Food and Drug Administration generally considers citrus pectin safe for human consumption. Furthermore, when you take it as directed, there are generally no side effects. The most commonly reported side effect with citrus pectin is mild gastrointestinal upset. This supplement may cause an allergic reaction if you have allergies to citrus fruit and in a rare number of people, can cause asthma symptoms.
Safety
Vitamin and supplement manufacturers in the United States are not regulated by the Food and Drug Administration, FDA. Therefore, they are not required to provide evidence that their products are proven effective or safe. Furthermore, manufacturers may not follow quality control guidelines or test their products for interactions with other supplements, herbs or medications. Use your discretion and consult with a professional prior to choosing a grapefruit pectin product.
