Attempting to sell a product which cannot work is very despicable IMO. The latest research on "Leaky Gut" completed in 2018 and published in 2019 by Daniel Vipond theorizes that Leaky Gut, a term that I dislike, is caused by pathogens in the digestive system. In Jan 2014 I worked this out myself long before that research was conducted. I know the precise location of the pathogens and how they cause Increased Permeability in multiple connected locations.
Therefore your useless supplement cannot and will not fix it, I guarantee that! It is a total waste of money IMO. It's like all the worthless claims that L-Glutamine will fix it when it will not because it is not antimicrobial and does not address the infection or biofilm(s).
Therefore don't waste your time and money on this.
