Bioclinic Naturals PGX Daily Ultra Matrix comes in a bottle of 180 Softgels. PGX is a dietary fiber that binds sugars and causes them to be digested more slowly. Additionally, because this fiber absorbs water as well, it can swell when consumed causing a feeling of fullness. Because of the lowered glycemic index of foods consumed with PGX, it is used to address cholesterol levels for both HDL and LDL.
