Why was this study done?

The cholesterol-lowering ability of fiber has been well established, but making a fiber supplement palatable can be difficult. This study was designed to investigate a combination fiber product (psyllium, pectin, and guar/locust bean gums – which is generally more palatable) and compare it with guar gum.

What did the study find?

The study found the combination formula had similar cholesterol-lower effects as guar gum in lowering cholesterol and easier for most people to take.
