Proteolytic enzymes like Nattokinase, Bromelain, Papain, Serrapeptase - what can we expect

Posted by iHerb Customer on Jan 18, 2018 | Verified Purchase

1. An improvement of digestion, especially for people who use protein based diet. Reduces the time of the digestion process two times or more. It helps to avoid intestinal decay connected to the undigested protein. Therefore, such enzymes supplementation is important in most of digestive disorders. In this case proteolytic enzymes are applied during the meal. 2. Barely anyone knows what is the primary purpose of plant enzyme production (e. g. pineapple, papaya, kiwi fruit). These enzymes are used to dissolve plant parasite's protein. In order to combat parasites in the human body, enzymes are used overnight or during fasting (out of meal time). Apart from parasites, enzymes allow unwanted protein contamination, blood clots and in some cases even cysts and tumors to be removed. Moreover, enzymes help to overcome such pathogens as parasites and some persistent fungi like Candida. Some pathogens produce biofilms or exudates containing protein, which helps them to adhere to the host's tissues. Therefore, proteases are applied as an anti fungi-biofilm factor. Literature 1.
