This is one of the highest strength bromelain products available, providing 1250 GDU\'s (gelatin-dissolving units) per tablet. This is a measure of how active this naturally sourced enzyme really is and is therefore more relevant than the weight of bromelain. Watch out for some USA imports which overstate the GDU level per tablet on the front of the label (one described as 3000GDU is actually 1250GDU).Bromelain is a protein digesting enzyme extracted from the stem of fresh pineapples which has traditionally been used as an aid to digestion. However, more recently, research has shown that some bromelain can be absorbed and have useful activity within the body. It is sometimes recommended to be taken alongside glucosamine.IngredientsEach tablet delivers:Bromelain400mgEnzyme activity level:1250 GDU**GDU= gelatin-dissolving unitsTableted with:Bromelain, Calcium Carbonate, Cellulose, Anti-caking Agents (Silicon Dioxide, Stearic Acid, Magnesium Stearate), Crosslinked Cellulose Gum, Tablet Coating (Hydroxypropyl Methylcellulose, Glycerin). Directions For UseFor joint care: 3 tablets (1 between each meal) for one week.
