Align is the doctor-recommended option, and it leans on that claim. The product page says Align has been the No. 1 probiotic recommended by gastroenterologists for over 15 years and that doctors recommend it nearly twice as often as any other brand. The formula is a single strain, Bifidobacterium 35624, developed by gastroenterologists and backed by more than 20 years of research per the page, and each lot is DNA tested to confirm the strain. One capsule a day is the dose, it needs no refrigeration, and the capsules are gluten free and vegetarian. Align does not sell on its own site, so there is no brand price to quote; we left its price pending rather than use a retailer figure. The page also notes its star rating comes from incentivized reviews. Buyers who want more than one strain or a prebiotic should look at Renew Life or Seed.
