Struggling to lose weight? A probiotic supplement could be the missing piece to your health and wellness puzzle. Eating well and exercising consistently will always be great habits, but having a probiotic supplement may be what finally helps you find your groove — and consistent results.

Scientific research has shown that taking probiotics may be a promising strategy when it comes to lowering body weight and BMI, showing a greater effect on people who took them for longer periods of time (National Library of Medicine). But what exactly should you be looking for?

How We Chose the Best Probiotic Supplements

As with your food, makeup or clothing, you’ll want to consider which probiotic supplement actually suits you as opposed to just grabbing the first one you see. Here are some things we considered when making this list for you:

  • We searched for specific probiotic strains e.g. Bifidobacterium and Lactobacillus
  • We only considered trusted brands we’ve either personally used or with great reviews and third party testing
  • We searched for gluten-free, vegan and clean options
  • We searched for other beneficial ingredients like prebiotics or digestive enzymes
  • We considered the CFU (colony forming units) count: the number of alive/active microorganisms in a probiotic supplement
  • We took budget into account, finding options at different price points
  • And more!
