This medpagetoday article implies that the supplement from SuperSmart was used (from the photo).

I don't see specific mention of MB40 on the packaging, but Walmart sells this for under $20.

For $16, I'll gamble that it will help.

MedPageToday just looked up any product with B. subtilis in it. There is no reason to believe that the study used this brand, or that this product contains the strain under study.
