The ingredients in ProFibe--soy protein, guar gum and citrus pectin-- long have been identified as ingredients for functional foods that offer medicinal benefits to humans. The combination of these components into a tool for reducing cholesterol is the story of ProFibe.
Both guar gum and citrus pectin are WSFs, which have been researched for more than 70 years and clinically proven to lower low-density lipoprotein (LDL--“bad”) cholesterol. Unfortunately, WSFs can be sticky and slimy in their natural state, making it very difficult for people to consume enough to derive medicinal benefits.
