INGREDIENT BREAKDOWN

One scoop provides the following:

This patented ingredient is a prebiotic fiber that comes from non-GMO corn starch that supports healthy digestion, promotes optimal gut health, and promotes feelings of fullness. In addition, Fibersol is backed by more than 30 years of clinical research.(1)

An ingredient you may not be familiar with is “FOS,” otherwise known as fructooligosaccharides. It contains a mixture of various oligosaccharides that are found in vegetables, fruit, and grains. FOS has several benefits. These include functioning as a source of beneficial gut bacteria and helping to ease constipation. In addition, FOS helps improve the absorption of iron, magnesium, and calcium. Finally, FOS provides immune system support due to their gut health functions.(2)

Polydexrose is a water-soluble fiber that slows digestion, promotes fullness, and provides healthy gut bacteria. In addition, it may help nutrient absorption, specifically calcium and iron. Finally, polydextrose is believed to lower insulin response after typical meals.(3)

This ingredient comes from the Plantago ovata plant. It’s a source of insoluble and soluble fiber. It improves digestive health and may help lower “bad” cholesterol. In addition, it promotes fullness, and functions as a prebiotic. Finally, psyllium husk eases constipation by soaking up water in the gut which creates a gel that supports regular bowel movements.(4)
