Tablets incorporating isoflavone plant extracts and methods of manufacturing them

A direct compression process for producing a tablet comprising the following steps:

• (a) mixing an initial formulation comprising
• an isoflavone-containing plant extract,
• a water-insoluble polysaccharide, wherein the amount of the water-insoluble polysaccharide in the tablet comprises at least about 15% of the dry weight of the tablet,
• a filler, and
• a silica gel glidant wherein the amount of the silica gel in the tablet comprises between about 1% to about 5% of the dry weight of the tablet;
• (b) milling the mixed formulation;
• (c) mixing into the milled and mixed formulation a micronized stearic acid, wherein the amount of the micronized stearic acid in the tablet comprises between about 1% to about 5% of the dry weight of the tablet;
• and
• (d) pressing the milled formulation into a tablet form, wherein the compression force of the press on the tablet is at least about 15 kilopounds.
