Synopsis

Source of validity: Scientific
Rating (out of 5): 4

A "fiber blend (proprietary)" typically refers to a mixture of soluble and insoluble dietary fibers, commonly including ingredients such as psyllium husk, inulin, oat beta-glucan, and others. Scientific evidence robustly supports the role of dietary fiber in reducing cardiovascular disease (CVD) risk. Multiple large-scale epidemiological studies and clinical trials have demonstrated that higher intakes of dietary fiber are associated with reduced levels of total and LDL cholesterol, lower blood pressure, improved glycemic control, and decreased risk of coronary heart disease and stroke. Soluble fibers like beta-glucan and psyllium are particularly effective at lowering LDL cholesterol, a major risk factor for CVD, by binding bile acids in the gut and increasing their excretion, which forces the liver to use more cholesterol to synthesize new bile acids.

The American Heart Association and European Society of Cardiology recommend increased fiber intake for cardiovascular health. Meta-analyses indicate that each 7-10 grams/day increment in fiber intake is associated with a 9% reduction in risk of coronary heart disease events. However, the exact efficacy of a "proprietary" blend depends on its specific composition, which is often undisclosed. While the general use of dietary fiber for cardiovascular health is scientifically validated, the evidence rating is not maximal (5) due to variability in fiber formulations and possible lack of transparency about ingredient proportions in proprietary blends.
