I bought this product for ingestion last October and bought 3 x 2 x 1 kg to 5 kg. I gave my three horses, Newfoundland senior 12 years, Jack Russell and myself. The stool of my horses is no longer wet, but solid. My horses, dogs, and I started to lose a lot less hair / fur. My nails had gray lines and white spots that disappeared after two months. I take a tablespoon in empty stomach each morning. I give my Newfoundland also a tablespoon and 1 teaspoon my Jack Russell, and my horses also 1/2 cup each morning as well. I have more energy since I started to ingest the product. I think it cleanses the intestines and absorb nutritions more easily.
