Top 5 Probiotics of 2018

Updated Feb 22nd, 2018

Within the past few years, the probiotics market has been EXPLODING. Doctors may have been prescribing them for a long time, but only recently have people started including these extraordinary supplements in their daily diets. Those who have started regularly taking probiotics have reported many improvements in their overall health. Here are some examples of the benefits thousands of daily users report:

  • improved digestive function
  • weight loss
  • lowered cholesterol
  • normalized blood pressure
  • less sick days

With so many brands of probiotics on the market, how can you find the right one? Because every product claims to be the “most effective“, it can be hard to find the probiotic that best suits your particular needs. Luckily, that’s what we’re here for.

This list ONLY includes probiotics which are manufactured in accordance with cGMP guidelines.

If a probiotic was NOT manufactured in clean, regulated conditions, as per cGMP guidelines then in all likelihood it will not only be ineffective but it could be POTENTIALLY HAZARDOUS!

There are 5 factors which impact our grade of each probiotic. They are listed and explained below.

      • Price – this one is pretty self-explanatory.
      • Potency – WAY too many companies leave their probiotics sitting around gathering dust, over 50% of the brands that we tested had ZERO live cultures left! Potency is the % of live cultures we discovered upon testing the brand, you’d be surprised at how many companies store their probiotics for way too long.
      • CFU (Colony-Forming Units) – this is the total count of all of the bacteria in the probiotic, VERY important because probiotics are ONLY EFFECTIVE IN ADEQUATE AMOUNTS.

      • Strains – total number of different types of bacteria in each probiotic, varies greatly and, along with strain diversity, affects the types and levels of benefits that you will notice.
      • Strain Purity – a combination of the effective concentration of the strains within the probiotic and the functional quality of the active cultures (the ability of the bacteria to perform its specific job).

          #1     BlueBiotics Ultimate Care                                                                                           2018 TOP PICK

Our Rating:          4.7/5ucbottle_small-fw

User Rating:        4.8/5  (1509)


Here’s Why:

  • 61 Billion live probiotics per serving (CFU)
  • 11 proven strains, only top proven strains are included
  • Endorsed by many doctors and health professionals
  • Contains S. Boulardii – possibly the most effective, but most expensive, probiotic strain. Many companies do not include S. Boulardii because of the cost
  • Small Capsules Designed to resist stomach acid – a must for any probiotic to be effective
  • Vegetarian capsules + free of potentially hazardous binders and fillers
  • Highest % of living cultures among top brands tested – by far


From Lactobacillus acidophilus to Bacillus Coagulans, the BlueBiotics blend is a veritable list of the most researched and proven probiotic bacteria known to science. And recent advances on the blend have made it the only full-spectrum probiotic supplement on the market, as it contains strains which are typically not available to the general public (Bacillus Coagulans and S. boulardii). The CFU count alone is remarkable enough, leaving most comparable spectrums in the dust… HOWEVER even more surprisingly our tests showed that a whopping 98% of the probiotic colonies in BlueBiotics were still alive, making this BY FAR the most effective probiotic supplement that we have ever reviewed. Also, because of the diverse pool of strains in BlueBiotics, users have reported a wide variety of benefits from weight loss, to increased energy, improved digestive health and cognitive function. Many of our staff switched to these probiotics, as well as myself and my family.

BlueBiotics capsules are also free from unnatural additives, contain a resistant-starch which serves as a food and fuel for the probiotic strains, and are enteric-coated to protect the strains which aren’t acid-resistant from being destroyed by your stomach acids.

          #2     Ultimate Flora Critical Care

Our Rating:          4.4/5                      User Rating:           4.3/5  (1288)

Here’s Why:

  • 50 Billion live probiotics per serving (CFU)
  • 10 top strains, many proven strains are included
  • Capsules Designed to resist stomach acid
  • Vegetarian capsules + free of potentially hazardous binders and fillers
  • High % of living cultures


Ultimate Flora tested significantly higher than the majority of general probiotic blends. Critical Care is composed of very well-documented probiotic strains and is an effective addition to any lifestyle, capable of conferring a wide variety of health benefits. The probiotic strains are not only diverse, they were also resilient to outside influences and, in many cases, were successful in establishing colonies within the digestive tracts of study participants.

Despite the hefty CFU advertised by Ultimate Flora, a large portion of the probiotic colonies were no longer alive upon analysis. This resulted in the effective CFU being much lower than what was claimed by the product.

Price: $35.99


CFU: 50 Billion…………..4.5

Strains: 10………………..4.2

          #3      Garden of Life RAW Probiotics

Our Rating:          4.3/5                      User Rating:           4.1/5  (845)

Here’s Why:

  • produced by a trusted, well known brand
  • 100 Billion CFU
  • 34 Strains
  • Vegetarian capsules + free of potentially hazardous binders and fillers
  • Reasonably high % of living cultures


Topping the probiotic market numbers at 100 Billion CFU divided between 34 probiotic strains, Garden of Life’s Ultimate Care probiotic was definitely a contender for our Best Probiotic of 2018. Free from preservatives and additives, RAW scored impressive marks across the board. Although this shortens the lifespan of the probiotics strains somewhat, buying in small quantities can easily solve this problem and – honestly – at CHR we always prefer purity to additives.

We were a little disappointed to see that this product was not enteric-coated. Although enteric-coating is not necessary for roughly 70% of the cultures in this probiotic, the remaining 30% (probiotics such as Streptococcus Thermophilus) will be devastated by your stomach acids. That is the only real drawback for an otherwise exemplary probiotic.

Price: $38.49


CFU: 100 Billion……………4.7

Strains: 34…………………..4.7

Living Cultures:…………..4.1

          #4      InnovixLabs Multi-Strain Probiotic

Our Rating:          4.1/5                      User Rating:           4.2/5  (912)

Here’s Why:

  • 31 Strains
  • 50 Billion CFU
  • Capsules Designed to resist stomach acid
  • High % of living cultures


The 31 strains in this probiotic include complete lactobacillus and bifidobacterium complexes, as well as two variants of the Streptococcus Thermophilus bacterium. Additionally, this supplement features enteric-coated capsules ensuring that your stomach acids won’t eat up the probiotics before they get to your intestines.

The only reason InnovixLabs didn’t outrank a couple other probiotics on this list was due to its worrying amounts of additives, including: Microcrystalline Cellulose, Hydroxypropyl Methylcellulose, and Silicon Dioxide.

Price: $23.99

          #5      Vitamin Bounty Pro 25

Our Rating:          4.0/5                      User Rating:           4.2/5  (947)

Here’s Why:

  • Produced by a trusted, well known brand
  • 25 Billion CFU
  • 13 Proven Strains
  • Designed to resist stomach acid
  • Very high % of living cultures


Vitamin Bounty’s probiotic contains a variety of well-studied strains and a competitive 25 Billion CFU. It also contains a natural prebiotic resistant starch, rice flour, to fuel the strains this probiotic supplies. Over 95% of Pro 25’s strains were still active and viable, the second highest observed strain viability out of all probiotics reviewed-to-date!

This product does contain the magnesium stearate additive, and the CFU/Strain count is a little under the recommended levels, however those are only a couple negative marks on an otherwise incredible product!

Price: $23.70


CFU: 25 Billion…………..3.3

Strains: 13…………………..4.4

Living Cultures:…………..4.7

    Did you try Vital Reds and if so how did it compare?

    1. JuliaJulia (Post author)

      Hello Karen,

      Gundry Vital Reds are not included because they are not strictly a probiotic.

      They only contain a small amount of probiotics.

  2. Audrey Hines

    I just ordered 3 bottles of probiotic from Probiotic America called Perfect Biotics. Is this a good company or a scam? Thanks

    1. JuliaJulia (Post author)

      You can find a list of probiotics we reviewed under probiotics > reviewed brands at the top of this page.

      Many brands did not make the cut to the top 5, and we’re not included on this page.

  11. Susan Green

    I would like to know which probiotic is best for IBS and fibromyalgia. Is important to use a product with with one or two cultures with the fibromyalgia?
    Thank you,


  12. JuliaJulia (Post author)

    Many users report that Probiotics help with IBS (Irritable Bowel Syndrome).

    I would start with the top of the list with a probiotic that contains saccharomyces boulardii – BlueBiotics.

    There is some research that suggests probiotics could help with fibromyalgia, I would recommend a probiotic with more that just 1-2 strains. Find one with top proven strains (5+) and a high CFU!
