What Is A Probiotic?

Probiotics are live bacteria and yeast that live in your gut microbiome.

Whenever you see the term “gut microbiome,” it’s referring to all of the microorganisms living within your gut. Some of them may be potentially harmful, so-called “bad” bacteria. On the other hand, some are thought to be beneficial, often called “good” or “friendly” bacteria, aka probiotics. [1, 2, 3, 4]

Researchers believe that having optimal gut health typically means having a good balance between the “bad” bacteria and the “good" bacteria. Ideally, they should co-exist peacefully within the gut.[1, 2, 3, 4]

Probiotics can be found in some fermented foods like yogurt, kefir, kimchi, sauerkraut, and miso. They are also available as dietary supplements. This may be more convenient for some people to consume, especially if they struggle to eat enough probiotic-rich foods.

Note: Individual results may vary. The benefits stated are based on personal experiences and subjective feedback and may vary from person to person.

Primal Probiotics are formulated with 31 billion CUFs from 12 dynamic probiotic strains, including L. acidophilus, L. rhamnosus, L. casei, B. longum, B. bifidum, and Bacillus coagulans. It combines these with PreforPro® and FOS (Fructo-Oligosaccaride) prebiotics.

Our team liked that the product comes in easy-to-swallow, once-daily capsules, making them convenient to add to a supplement routine.

The formula is third-party lab-tested and made in the USA in a GMP-certified facility. To top it off, they’re backed by a 90-day money-back guarantee. Primal Probiotics’ pricing stands out, especially when you buy multiple bottles or sign up for their easy and convenient subscription service.

2. Ultimate Flora Probiotic

by RenewLife

PROS

Over 20 billion CFUs
Made in the USA
12 diverse strains

CONS

No prebiotics
No L. reuteri, B. longum, or B. bifidum

BOTTOM LINE

This product is a great budget probiotic featuring a high CFU count from 12 diverse probiotic strains. It contains both Lacto and Bifido probiotic strains and is delivered in a once daily capsule. Unfortunately, you may note that it was missing some of the probiotic strains we were looking for as well as prebiotics. Although it had a 60-day money-back guarantee but still preferred products with a 90-day guarantee like our number one pick.

B+

GRADE

3. Probiotics

by Nature's Bounty

PROS

Contains L. acidophilus
GMP certified
1 tablet serving size

CONS

Only 1 probiotic strain
No Bifido strains

BOTTOM LINE

Nature’s Bounty probiotics is a low-cost, GMP-certified supplement formulated to support digestive health with over 100 million active Lactobacillus acidophilus. This product comes in tablet form, which may be a downside for some since it’s generally thought that probiotics are better formulated in capsule form. However, the main reason this product didn’t make it to the top was that it only contains one probiotic strain.

C+

GRADE

by Culturelle

PROS

1 capsule serving size
Includes inulin (chicory root)

CONS

Only contains 1 probiotic strain
Only 12 billion CFUs
No Bifido strains

BOTTOM LINE

Digestive Daily Probiotic by Culturelle is a probiotic formula that includes 12 billion CFUs of the probiotic strain Lactobacillus rhamnosus GG. You may note that they include the prebiotic inulin in the formula and that it comes in a one-capsule serving size. However, the fact that this formula only contains one probiotic strain places it fourth on our list.

C+

GRADE

4. Digestive Daily Probiotic

5. Raw Probiotics

by Garden of Life

PROS

Once-daily capsule
High CFU count and number of probiotic strains
Includes enzymes blend

CONS

No 90-day money-back guarantee
No prebiotics
Contains milk

BOTTOM LINE

Raw Probiotics by Garden of Life is a once-daily probiotic supplement that includes 100 billion CFUs of both Lacto and Bifido probiotic strains. This product includes a diverse selection of strains and has a high CFU count. While this product was relatively comparable to the other products on this list, the brand does not offer a 90-day money back guarantee which can be disappointing. Additionally, although that the formula includes a digestive blend, you may note that it did not include prebiotics and did contain milk.*
