Supersmart - Lactobacillus Reuteri 5 Billion CFU per Day - Probiotic Supplement | Non-GMO & Gluten Free - 60 DR Capsules

Fellow IBS-sufferer here. Runs in my family.

So doing a search for "Reuteri" on Amazon, I immediately see several pages worth of supplements, with such helpful reviews as "HELPS DIGESTION. ENLARGES TESTICLES."[0]

How do you separate the trustworthy supplements from the snake oil?
