My husband is taking this product to heal SIBO. What a difference it made in his well being. He also has issues with his vagus nerve, which we know now has caused all the other symptoms like shortness of breath, heart not pumping properly (CHF), water retention and the digestive issues (Sibo) which is all due to a low vagal tone. If you have all these symptoms do your research on Vitamin B1 get the vagus nerve working and support your digestion with spore probiotics that will take off the pressure of the breathing and heart, you will notice you sleep better too. Also research on Melatonin it is so much more than just a sleep aid, especially with gut issues. Detox first from heavy metal and chemicals and then parasites and you are on your way to health.
