Hydrogen sulfide is an important signaling molecule in the human body. It reduces blood pressure, reduces oxidative stress, and may even delay aging.


However, hydrogen sulfide is also produced by certain bacteria in the gut that convert hydrogen into hydrogen sulfide, and when overproduced in the gut, it can cause some very unpleasant symptoms.


Excess hydrogen sulfide production has been connected with irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), colorectal cancer, and more.

In this 3-part course, we cover:

- How to know if you have hydrogen sulfide overgrowth

- The utility of breath testing and stool testing for hydrogen sulfide

- The four major sources of sulfur in the gut

- Evidence-based strategies for addressing hydrogen sulfide overgrowth
