Smidge Sensitive Probiotic Supplement: A "Clean" Choice

Smidge Sensitive Probiotic Supplement Is A

Smidge Sensitive Probiotic is formerly known as GutPro.

Organic 3, Inc., the makers of GutPro, changed the name to Smidge to secure a brand and international trademarks. Smidge is a company based in Michigan, USA at the same address used by Organic 3.

Here is a table from Smidge showing the comparison of the products. From my information on GutPro products, there have been some slight changes in the orders of probiotic bacteria in the new products:

What Probiotic Strains are in Smidge Sensitive Probiotic?

The product is said to contain "eight clinically-proven strains of probiotics for gut health" in the powder and capsule supplements, although the strains are not designated. Seven are human strains, and one is a plant-based strain. One Smidge spoonful contains 3 billion CFU, and the product includes a spoon.

The eight strains are:

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

The Smidge Sensitive Probiotic capsules have the same bacteria in the same order, whereas in GutPro the gasseri and salivarius were switched in the order of listing between the powder and the capsules. Two capsules contain 10 billion CFU.

Smidge Infant Probiotic Powder

The Smidge Infant Powder does not contain L. plantarum. 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, especially when L-lactate is produced by other strains in the same formula, such as those in Smidge Sensitive Probiotic.

The order of the bacteria in the infant powder, which is a slightly different order than GutPro Infant, are:

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

There are 1.45 billion CFU per Smidge spoonful, and the product contains a spoon.

The dosing for the Optimal Probiotics is to start with one capsule daily with food, and then increase to 2 capsules together, or as directed by a practitioner. Two capsules contain 20 billion CFU.

What is the Recommended Dosage of Smidge Sensitive Probiotic?

For the capsules, one adult serving is 2 capsules per day providing 10 billion CFU, although they suggest to start with one capsule. 

For the powder, one adult serving is 1 Smidge spoonful providing 3 billion CFU. Each bottle has 1000 adult servings.

For the infant powder, the dosage is 1 Smidge spoonful containing 1.45 billion CFU. Each bottle has 750 servings.

Powders may be sprinkled on cold foods. Avoid taking probiotics with hot foods or drinks.

What are the Pros of Smidge Sensitive Probiotic? 

The pros of Smidge Sensitive Probiotic as I see them are:

  • Multi-species
  • Tested for contaminants
  • Freeze-dried for better stability
  • Non-GMO
  • It is a "clean" probiotic supplement compared to many on the market. There are no excipients such as magnesium stearate, silica or titanium dioxide.
  •  It contains NO milk/casein, eggs, fish, shellfish, tree nuts, peanuts, wheat, gluten, or soybeans.
  • It contains NO artificial colors, flavors, or preservatives.
  • Strains are grown on a non-dairy, non-soy vegetarian non-GMO culture.
  • Other ingredients are limited or nonexistent
  • Vegan
  • 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
  • Smidge controls when and how the supplement is shipped to insure that it is not ordered and left in unrefrigerated storage over a weekend. Probiotics only ship Monday through Wednesday.  Regular shipping uses a 2-day service. Overnight shipping is available.
  • The probiotic powders are contained in amber glass bottles for maximum protection against light, and a dessicant is provided in the bottle to protect against moisture.

There are 306 reviews with a 4.9-star rating on their website for the Sensitive Probiotic Powder and 153 reviews with a 4.8-star rating for the capsules at the time of this writing (September, 2023). Here is a sampling of consumer favorable reviews on their website:   

"Worked really well for my allergies, actually better than anything I've ever tried. I'm no longer the most allergic person in the crowd, or even allergic for that matter. Thank you so much Gut-Pro!!!" 7/6/2020

"When kids are young you never know what they’re actually allergic to, I gave these probiotics to my newborn when he got thrush and Bought it again To keep on hand if they ever have to have anabiotic’s. I’ve taken probiotics a lot with my celiac and you never know what you’re going to get. I know these are good because my newborn did amazing on them and he was super sensitive as a baby. that’s why I spend the money on gut pro versus others."  4/23/2020

"Love and appreciate this product. It is effective and powerful so you need to start slow and move up. My son who has Crohns uses this and it is a very supportive product. " 3/28/2020

"I started taking GutPro [Smidge™ Sensitive Probiotic] ~4.5 years ago, at the recommendation of my chiropractor based on the book "The Epidemic of Absence." After the prior round of allergy shots became ineffective, I experienced symptoms of intense allergies the following spring. I've been allergic since I was a child to environmental things (spring pollen, weeds, animal dander, dust, etc.), Now I no longer have allergies, and no longer need allergy shots (the previous five (5) rounds of allergy shots only had temporary results for me). I continue to take GutPro [Smidge™ Sensitive Probiotic] and find it the best! And it's so cost effective when compared to allergy shots and the time getting shots every 4-6 weeks. Initially it took approximately three months before my allergy symptoms totally disappeared, and it was totally worth the wait!"  11/21/2019

I ordered this for husband and self to help with tummy issues. We are seniors and sometimes had bathroom issues. After starting this product, we are both MUCH improved. Will order again and even recommended it to husbands acupuncturist.” 10/26/2019

The Smidge Infant Powder had 57 reviews with a 5-star rating. Here is one review:

"We started this probiotic when my baby was about a month old. She was having terrible gas pains and spitting up a lot of breastmilk after each feeding. She would wake up in the middle of the night screaming with gas pain and had to be rocked back to sleep multiple times a night. We have been using this probiotic for a little over a month and are SO happy we found it. Baby still gets a little gas but significantly improved from what he was having, the spitting up has decreased immensely too. We still use just a small amount every other day. It is the only probiotic I could find that wasn't mixed with additives or preservatives. I was nervous to get a powder but it is such a small amount needed I just wet my nipple with breastmilk and put the powder directly on the nipple. It is more pricey than other probiotics but we use such small amounts this will last well over 6 months -1 year (& you can't beat the ingredients!) . Cannot say enough good things and we will continue to use this product for this baby and any future babies!"  2/18/2020


There were no unfavorable reviews!!!

What are the Cons of Smidge Sensitive Probiotic?

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.
  • As with most probiotic supplements, this one requires refrigeration after it is delivered.
  • 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 5 billion per capsule. However, the powder is much more concentrated and is a budget-friendly option.
  • All sales are final
  • Sold only online or through practitioners such as myself

Where to Find Smidge?

This probiotic supplement is sold online It is only shipped Monday-Wednesday using 2-day service, or an overnight option is available. I can order it for you if you are a nutrition client in my practice for whom it is a good fit.

Is Smidge Sensitive Probiotic 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 Smidge products have "generally recognized as safe" species of Lactobacillus and Bifidobacterium, are free of most allergens and are packaged and shipped properly. I appreciate the care in handling and shipping that Smidge utilizes.

One Other Note

If you decide to take Smidge Sensitive Probiotic, or any of the other Smidge probiotics,  I would combine the health benefits of them with the benefits provided by:
