What is the best probiotic to take while on triple antibiotic therapy?

When I started antibiotic treatment for MAI, my gastroenterologist recommended Florastor. It is Saccharomyces bollardii, and apparently it is the only brand established in (small) studies to survive and work against antibiotic gi effects. That doesn't mean it's the only brand of Saccharomyces bollardii that will be effective, just that it's been studied. I have found it very helpful and have continued it since being off antibiotics even though it's pricey.

I have also looked on the iHerb website. My drug regimen will include Rifampin, Ethambutol, and Azithromycin for 12-18 months. The literature suggests both Saccharomyces boulardii and Lactobacillus rhamnosus GG, and some lean toward recommending the former, since it is a probiotic yeast rather than a bacteria, so it will not be killed by the antibiotics I will be taking. I see my pulmonologist in 2 weeks and I want to have all of my questions lined up. I will start the treatment at that time.

I always look for peer-reviewed studies - and more than one - but there are precious few that I trust. And of course, the studies do not reveal where they source their cultures because they cannot be seen to promote a given supplier. However, since I used to attend a number of CF conferences for my work, I did buttonhole one researcher who admitted they got their L. acidophilus from Culturelle. This was years ago, but I still use that one. It worked great for IV antibiotic-induced diarrhea, but now I'm searching for probiotics to help treat SIBO, so I'm going to have to try to contact some of my old (and I do mean old) colleagues.
Please note I am not promoting Culturelle. The company may have changed hands 10 times since then for all I know. Also, YMMV!

I think this one looks promising for use during antibiotics. Spaced 2 to 4 hours after. It includes Sac. Boulardi but you could probably take extra of that as well.

@corina3892 Hope this is not common but with iHerb buying Vitacost there are some changes.
"Kroger" no longer owns them.
My order was messed up by them. I double checked all information I was inputting.
First order went to the Bronx rather than OKC. Finally messaged to say where is it.
Outcome. They refunded the money and had to reorder all and make sure they applied and gave the the original 20% off coupon. They took forever to get the second order out.
That meant it took two weeks to get what I needed in two days.
Just be aware....
and know they appear to no longer take telephone calls.....e mails now.

Apparently you need to gain access to shop for these products through a licensed health care professional... ?
