We’ve researched and tested dozens of natural probiotics—these are our top seven picks, made with organic ingredients.

Probiotics are living organisms that are good for you (yes, they exist!)—think healthy bacteria, yeast, and spores. Once ingested, probiotic strains help restore your gut health, heighten immunity, reduce inflammation and allergies, and even support your mood.

Why should you look for natural and organic probiotics?

Natural and organic probiotics offer numerous benefits that conventional probiotics miss out on. They are free from harmful chemicals like pesticides, GMOs, and synthetics. Organic farming practices also contribute to a healthier soil ecosystem and higher quality ingredients that can be used in probiotic formulas to boost their benefits (think prebiotic fiber from organic fruits). Organic probiotics are also more sustainable, as less synthetics and better biodiversity in farming practices minimizes adverse impacts on our environment.

As with any ingestible supplement, knowing what to look for in a healthy, effective probiotic is important. According to both the Cleveland Clinic and WebMD, you want to search for quality brand names. You’ll also want to look for a probiotic with one billion or more colony forming units (CFUs) or active fluorescent units (AFUs), and check that it aligns with your preferred dosage and form (consider capsules, gummies, or powder). 

We’ve found seven of the best and most trusted natural probiotics out there, ranging from USDA certified organic formulas for immunity, to vegan options for gut health and digestion, to natural capsules for pregnancy or vaginal health. We also recommend chatting with your doctor for personalized suggestions or before starting any new supplement. If you have a probiotic you already love, we’d love to hear in the comments below!

Our criteria:

  • NATURAL, HIGH QUALITY INGREDIENTS | Each of these probiotics is made from natural ingredients that are third-party tested and highly effective.
  • AFFORDABILITY | We’ve offered a variety of choices for probiotics at various price points, prioritizing budget-friendly options.
  • ACTIVE FLUORESCENT UNITS (AFU) | Each of these brands that provide detailed information on their CFU/AFU count, ensuring plenty of gut friendly microorganisms are reaching your colon, where they’ll go to work!

AG1 Review | “I’ve trialed a variety of different supplementation products from a wide array of companies – some have worked better than others. And I know some are good for me over the long term even if I don’t notice anything, but with the cost of living, I only stick with a supplement if I actually FEEL a difference in my daily life. With AG1, I notice feeling just better overall, and I get more unsolicited compliments from people about me looking good, so it must be doing something! Moreover, I noticed when I went a couple months without it after first trying it, I definitely felt less energy, more brain fog, etc. All that said, I’ve decided to stick with it!” – Jeff M.
