Green coffee

Green Coffee Extract/Nutrient depletion:

  • CalciumCalcium: Studies in rats found the solubility of calcium to decrease when coffee (caffeinated or decaffeinated) was mixed into the diet (95).
  • GlucoseGlucose: Green coffee and its constituents have been demonstrated clinically to lower blood postprandial glycemia (129; 21; 32).
  • IronIron: Polyphenolic compounds found in coffee (namely chlorogenic acids) are potent inhibitors of iron absorption in humans (105); this iron-reducing activity is not affected by caffeine (106). Studies in rats found the solubility of iron to decrease when caffeinated (but not decaffeinated) coffee was mixed in the diet (95).
