Restored gut health
17 people found this helpful
I had c. Diff that wouldn't improve with prescription drugs, and this product restored my gut. I experienced severe gastroenteritis during Easter and have not felt right since. I've been taking Culturelle and lots of yoghurt, but this has been what I needed. I had used this about seven years ago, and it normalised my gut health then. Its ingredients are similar to those in the very expensive Florastar, so I'm thrilled with the effectiveness and affordability of the Jason brand.

Effective microbiota support
3 people found this helpful
Brady's yeast supports beneficial microbiota in the gut and enhances immune function, while MOS prevents microbes from adhering to intestinal cells. Taking Brady yeast has significantly reduced my bowel movements and the duration of diarrhea associated with gastroenteritis, with no side effects observed.

I used to order Jarrow products from another company, but living in Japan makes delivery a challenge. I found iHerb and decided to give them a try. Within six days, I received my excellent Saccharomyces Boulardii + MOS. They are very effective as a preventative against gastroenteritis, from which I previously suffered. I highly recommend iHerb to friends!

High effectiveness noted
1 people found this helpful
Highly effective for relief of gastro disorders. This is very beneficial in reducing symptoms of severe gastro infection. Particularly good for nausea, it also has positive effects on appetite and well-being. I have suffered from C. diff for 12 months, and this medication has made the difference between surviving or not—simple as that.

Quick recovery noted

This product is nothing short of wonderful. Living in Japan, the rate of gastroenteritis is surprisingly high, and I've experienced it, unfortunately losing eight pounds in two days. I do NOT recommend this approach to weight loss. A good friend introduced me to Jarrow Formulas’ probiotics, and I felt better almost immediately. I am thrilled that iHerb can send this product to me here. My thanks to the good people at Jarrow Formula and iHerb!
