thats a lot of pepsin and not very much HCL at all
When I took betaine i used to use these
you can see how the ratios are completely different. I took about 6 of them 30 minutes after meals.
HCL will do nothing to your beneficial bacteria, your beneficial bacteria shouldn’t be located in your duodenum really. Your body neutralizes the chyme pretty fast once it enters your small intestine too. So I wouldn’t worry about that aspect of it at all.
