Firstly, I would like to say that I experienced the contact with Marco (owner) as pleasant. He really takes the time for you. I took 1x DF5. My complaints were flatulence and I am sensitive to gluten and milk. I now notice that I pass far less gas and I can tolerate gluten and milk better. I also notice this when I take a protein shake and don’t suffer from smelly farts. Based on my experience, I can definitely recommend a poop transplant with gezonde darmflora!
