GutPro Probiotic Supplement: A "Clean" Choice

GutPro Probiotic Supplement Is A
Smidge Sensitive Probiotic Supplement Is A

GutPro by Organic 3, Inc., a company based in Michigan, USA, was a multi-strain probiotic marketed to “provide essential elements for digestive health, without certain bacteria strains and additives that can irritate some people.

It is now available starting in July 2020 from the new company name of Smidge in a Sensitive Probiotic Capsule, Sensitive Probiotic Powder, Infant Powder, or Optimal Probiotic Capsules.

Please see my Smidge page to view the latest review of the products, as some things have slightly changed during the transition from GutPro to Smidge..

The following information applies to the former GutPro products:

It is also is marketed to be based on research gathered from gut-health promoting communities such as GAPS Diet (Gut and Psychology Syndrome), Body Ecology Diet, GFCFSF, Autism/PDD-NOS and PANDAS/PNAS. The website says that it is not meant to treat any specific medical condition nor is it designed to be compliant with any specific diet.

I was confused at first trying to figure out the connection between Organic3, other GAPS websites and the aforementioned communities, especially for the GAPS diet. Here is what I found out: Gut and Psychology Syndrome™ is the trademark and copyright of Dr. Natasha Campbell-McBride. She developed the GAPS Nutritional Protocol, wrote the book, Gut and Psychology Syndrome: Natural Treatment for Autism, Dyspraxia, A.D.D., Dyslexia, A.D.H.D., Depression, Schizophrenia, and has the website, She also authored many articles and another book.

The website and GutPro are owned by Organic3, not by Dr. Natasha Campbell-McBride, although her picture is at the bottom of the webpages. The is also an independent, privately-owned company which is separate from Dr. Campbell-McBride, but they distribute her book, Gut and Psychology Syndrome, as well as offer products which are supported by the GAPS Nutritional Protocol.

Therefore, my understandings are that the GutPro supplement and the non-Dr. Natasha websites are not specifically endorsed by Dr. Natasha Campbell-McBride, and that GutPro complements information in the GAPS and other communities but is not specifically endorsed by them. However, GutPro is GAPS compliant.

What Probiotic Strains are in GutPro?

The bacteria used are said to be “thoroughly researched, documented and banked in recognized microbial culture collections.” There are eight different bacteria in the powder and capsule supplements, although the strains are not designated:

  1. Lactobacillus plantarum
  2. Bifidobacterium bifidum
  3. Bifidobacterium longum
  4. Lactobacillus salivarius
  5. Lactobacillus gasseri
  6. Bifidobacterium infantis
  7. Bifidobacterium breve
  8. Bifidobacterium lactis

The capsules have the same bacteria, although the gasseri and salivarius are switched in the order of listing.

The infant powder (manufacturer recommended ages 3 months-2+ years old) does not contain L. plantarum and 50% of the formula is B. infantis. The L. plantarum is omitted because the international food standards (Codex Alimentarius) of the World Health Organization ( states that only L-lactate should be in infant formulations. L. plantarum produces both L- and D-lactate. Debate on the restriction of D-lactate in infants and its potential to cause acidosis continues.

The order of the bacteria in the infant powder are:

  1. Bifidobacterium infantis (50%)
  2. Bifidobacterium bifidum
  3. Bifidobacterium longum
  4. Lactobacillus gasseri
  5. Bifidobacterium breve
  6. Lactobacillus salivarius
  7. Bifidobacterium lactis

What are the Other Ingredients in GutPro? 

The other ingredients at the time of this writing are:

  • Hydroxypropyl methylcellulose, cellulose and L-leucine in the capsules
  • The powder formulas have no other ingredients.

Please verify ingredients of any supplement prior to taking it.

What is the Recommended Dosage of GutPro?

For the capsules, one adult serving is 2 capsules per day providing 10 billion CFU. The capsules should not be opened. The child serving is 1 capsule per day, assuming the child is able to safely swallow the capsule.

For the GutPro powder, one adult serving is 1/32 teaspoon providing 25+ billion CFU. Each bottle has 240 adult servings. The child serving is half of the adult one, or 1/64 teaspoon. For convenience in measuring such a small amount, Organic 3 sells a custom set of measuring spoons.

For the infant powder, the dosage is 1/64 teaspoon containing 6+ billion CFU.

What are the Pros of GutPro? 

The pros of this probiotic supplement as I see them are:

  • Multi-species
  • Non-GMO
  • It is a "clean" probiotic supplement compared to many on the market. It contains NO wheat/gluten, dairy, corn, soy, eggs, fish, shellfish, tree nuts, peanuts, yeast, artificial colors, flavors or preservatives. Strains are grown on a non-dairy, non-soy vegetarian culture. However, the products are produced in a manufacturing facility which may use soy, although the equipment is cleaned and sterilized in accordance with GMP.
  • Other ingredients are limited or nonexistent
  • Produced in a GMP (Good Manufacturing Practices) facility
  • All raw materials and finished product are verified by an independent lab for purity and stated potency
  • Potency is guaranteed through one year from manufacturing date. Organic 3 states that they can “generally guarantee 100% potency… for one full year upon receipt of the product”, providing it is stored properly. To know the “best-buy” date you should contact customer service with the lot number.
  • The regular powder formula is potent so one bottle has many serving sizes. One bottle of powder is equivalent in CFU to 10 bottles of the capsules.
  • Product has refrigerated storage and cold-pack shipping, including a dry-ice option
  • Organic3 controls when and how the supplement is shipped to insure that it is not ordered and left in unrefrigerated storage over a weekend.

There are a few practitioner (including GAPS practitioners) and a couple of consumer favorable reviews on their website:   

I received the package well protected with insulated packaging and an ice pack that I paid extra for. I started out with 1/2 the child’s dose, “drop”, building up the a full “drop” serving at the end of a week. I am now at a full “smidgen” one week later. I started these probiotics due to a systemic yeast infection that I suspect I have had for years. I am experiencing ‘die-off” symptoms: chills, extreme fatigue, etc. Each day they are less and I look forward to feeling normal eventually. I am watching my diet and curtailing sugar consumption. I bought this product mainly because it was gluten and corn free, which I am intolerant on both. I also liked that I could control my dosing-no capsules. This is the first time I have taken probiotics daily, I probably will continue from now on. I have other issues, insomnia and acid reflux that seem to be resolving and I am hopeful they will go away.” 3/26/16

GutPro is powerful stuff and does its job, but treat it with respect. I had to start even more slowly than recommended, and increase more slowly, too, because it's so effective.” 3/28/16

This probiotic heals my leaky gut. My problems are not cured, but they are lessened.” 4/17/16

I have tried more than a few brands and I always come back to GutPro. The best analogy I can think of is that it's like comparing $400 shoes to $10 shoes. There is just a world of difference in comfort and quality. With a child with many food intolerances and allergies and another with PDD-NOS, it really helps me that this has no fillers and everyone in the family can take it together.” 5/23/16

There were no unfavorable reviews.

What are the Cons of GutPro?

The cons of this probiotic supplement as I see them are:

  • Only the species are given; you don't know which strains are in the product since the information is proprietary.
  • Only the total CFU is given; you don't know how much of each species is present, except for the infant powder in which 50% is B. infantis.
  • As with most probiotic supplements, this one requires refrigeration after it is delivered, but should also be shipped with at least a cold pack during transit. It is shipped from either Washington state or Virginia Monday-Wednesday via 2-day express mail.
  • No studies with this supplement as a whole supplement have been performed to my knowledge, and since neither the strains nor the amounts of each strain are listed, it is not possible to predict what specific benefits this product will have. Note that there are very few probiotic supplements which undergo clinical studies.
  • Compared to other multi-species probiotic supplement capsules, this one contains a lower number of total CFU of 6 billion per capsule. However, the powder is much more concentrated and is a budget-friendly option.
  • No money-back guarantee
  • Sold only online or through practitioners such as myself

Where to Find GutPro?

This probiotic supplement is sold online and it is only shipped Monday-Wednesday using 2-day service. It may also be stocked by some health practitioners like myself. I can order it for you if you are a nutrition client in my practice for whom it is a good fit.

Is GutPro the Right Supplement for YOU?

If you would like help in determining if this probiotic supplement is right for you, please consider nutritional consultations with me. A supplement is just that: supplemental to other healthy lifestyle factors. A supplement should not replace good eating habits and taking care of oneself and nutrition consultations can certainly help with those.

The powder is a high potency supplement. All GutPro products have "safe" species of Lactobacillus and Bifidobacterium, have a nice third-party verification, are free of most allergens and are packaged and shipped properly. I appreciate the care in handling and shipping that Organic3 utilizes.

Since the powder formula is concentrated, I think it is best to use their special measuring spoons to ingest the recommended dosages and increase the dosage over time. In many cases, especially once a higher dosage is established, eyeballing the amount based on how it fits into a 1/4 teaspoon or 1/8 teaspoon standard measurement may be adequate, but doing so in the beginning may cause uncomfortable symptoms.

Thanks to Christine for suggesting a review of this probiotic supplement!
