I have already tried Psyllium from different manufacturers. Again and again disturbed or similar small stones With the price I am also very satisfied. Even with the new, additional shipping and handling charges this product is still cheaper than it is offered in drug stores or pharmacies. My recommendation for "cranking" digestion: the morning before breakfast 2 tablespoons psyllium in about 200 ml Water swell 10 minutes. I then drink another large glass of water and my 2 cups of coffee.
