PectaSol® modified citrus pectin is a complex polysaccharide. Regular citrus pectin molecules are long chains of highly branched glucose molecules, which are too large and complex to be absorbed in the gastrointestinal tract. PectaSol® modified citrus pectin has undergone a unique manufacturing process that renders the pectin molecules shorter and less branched than regular citrus pectins. This special process ensures the lowest degree of methylation with a molecular weight within a specific range of 10,000-20,000 daltons. Low methylation increases the number of galactosyl binding sites, thus enhancing the intensity of modified citrus pectin’s immune supporting and cellular health benefits. The shorter, unbranched chains of modified citrus pectin optimize its reliable absorption, bioactivity, and utilization of its important polysaccharide components. PectaSol® modified citrus pectin is rich in galactosyl residues, the key component thought to confer modified citrus pectin’s health benefits. Galactosyl residues interfere with the binding of galectins, a type of protein on the surface of cells. Galactosyl specifically interferes with the carbohydrate-binding galectin 3, which has been identified on prostate, breast, colon, brain, skin, lymphatic, and larynx cells. By interfering with galectin binding, galactosyl interferes with undesirable cell-cell interactions, thereby exerting unique assistance to the immune system. A clinical trial demonstrated PectaSol’s ability to bind and remove toxic heavy metals from the body, without affecting essential minerals. Heavy metal removal with Pecta-Sol has been shown in multiple case studies to play a role in ongoing health maintenance. A hospital case study in 2008 reported that PectaSol significantly decreased toxic lead levels.
