Sevenhills Wholefoods Psyllium Husk powder is a finely ground version of psyllium husks (mesh 100) and by far the most convenient way of supplementing with Psyllium. Because it is finely ground, it disperses more easily in liquid than the husks and it is easier to drink. Psyllium Husks are divided into different categories according to the purity – our Psyllium Husk is a minimum 95% pure.
