Psyllium, or tea tree seed husk, is an insoluble natural fibre that swells on contact with water. The hardness of the fibre (20 mesh) is safe for the intestines. The fibres in the psyllium husk increase and soften the mass of the stool, which in turn activates the bowel. The fibres cleanse the intestines by binding with harmful compounds. Fibres increase the osmotic pressure in the intestine, and lactic acid bacteria thrive faster and more efficiently. Real blueberry powder is a natural source of vitamin C. Gluten and lactose free.
