I agree David. It took my belly about 2 weeks to settle down after starting them but I feel so much better overall now.

I have been taking pro and prebiotics for a long time. Helps with constipation.

Elaine, I found this description of PS128 supplements. Please note,this info came from an ad. I have not yet found any of the 12 clinical trial results mentioned in this statement. So, please proceed with caution and consider talking to you doc before taking anything new. If you put PS128 in the search field, you will find a bit more info and several sources where it is sold.
- Backed by 12 clinical trials, PS128 has been shown to help balance serotonin, dopamine, cortisol and other molecules that affect mind, mood and movement in people with Parkinson's disease, autism spectrum disorder and other neurological conditions.

I read the article. I am going to start taking with my next meal.

Probiotics are worth a shot.
