GutPro® Infant Probiotic Powder - by Organic 3, Inc.

GutPro® Infant is a gentle, yet potent custom probiotic created especially for your baby's developing digestive system.

This pure powder contains seven clinically-proven probiotic strains that are naturally found in healthy infants. And it’s designed to help colonize little intestines with beneficial bacteria from the get go. 

Bifidobacterium infantis — a notable strain that dominates in breastfed babies' intestines — comprises 50% of GutPro® Infant, as studies show it supports healthy digestion, growth and immunity in infants (see our ingredients section for more).* 

Just as important, GutPro® Infant does not contain certain strains (or prebiotics) found in other commercial brands that can cause histamine intolerance, d-lactic acidosis or other adverse reactions. 

You also won’t find common allergens, additives or fillers. 

Don’t forget to add our mini spoon set, which comes with a handy dosage chart and allows you to measure the amount that’s right for you. 

How do the new spoons compare to your former spoons?

These spoons are designed to take the guesswork out of your dosing. The former “Drop” spoon is now spoon 2. The former “Smidgen” spoon is now spoon 3. There’s no equivalent for the new spoon 1, as it’s a new, smaller size that’s designed to be a starting point when taking Organic 3 powder supplements.

Spoon 1 None 3+ billion
Spoon 2 Drop 6+ billion
Spoon 3 Smidgen 12+ billion



GutPro® Infant contains only the highest-quality probiotic bacteria. All strains have been thoroughly researched, documented and banked in recognized microbial culture collections. Further, all strains are non-GMO and American Type Culture Collection certified.

Below is a list of ingredients in GutPro® Infant, and information on why we’ve included them:

B. infantis: Bifidobacterium infantis is prevalent in the gastrointestinal tracts of breastfed babies, as it feeds on unique oligosaccharides found in breast milk that babies cannot digest — leaving little room for unwanted bacteria and supporting a healthy digestive ecosystem.* In a recent study, moms and infants received a B. infantis preparation and lactation support from a week to three weeks after birth. The bacteria quickly established themselves in the babies, crowding out other gut bacteria that are associated with intestinal problems and immune-related diseases such as asthma, allergy and autoimmune disease.* Meanwhile, another study discovered that nearly all babies born in developed nations (including the U.S.) no longer have B. infantis. It was hypothesized that an increase in c-sections, infant formula and antibiotics led to the reduction in this beneficial bacteria. This study stated that a stressed microbiome composition may lead to chronic inflammation and immune-mediated diseases, highlighting an increase in infant intestinal dysbiosis. The good news, according to research noted in the same study, is that remodeling of the gut microbiome in breastfed infants fed B. infantis improved gut function and ecosystem productivity.* B. Infantis (as well as several other strains in the Lactobacillus and Bifidobacterium families) also produces folate, which is necessary for infant development and growth and the creation of red blood cells.*

B. bifidum: In one study, Bifidobacterium bifidum was the second most common bacteria in infants' guts (B. infantis was first). B. bifidum seems to support the immune system and help the digestive system stay on track: A clinical study showed that B. bifidum helped academically stressed college students make it through the winter semester with fewer absences and less colds than the students who didn't take the probiotic.* Another clinical study indicates B. bifidum may help with abdominal discomfort, gas and bloating.* And a randomized placebo-controlled study also showed that B. bifidum may help with stress-related diarrhea.*

B. breve: Found in human breast milk, Bifidobacterium breve can also digest human milk oligosaccharides (but not as thoroughly as B. infantis). It's considered one of the first colonizers of the human intestinal tract. A few clinical trials involving preterm babies indicated that B. breve works well in helping to establish a healthy gut ecology.* In one of these studies, researchers concluded that B. breve also seems to help these tiny babies gain weight.* And, clinical research has demonstrated that when combined with a gluten-free diet, B. breve can help restore microbial balance in the digestive tract of children who have experienced some intestinal inflammation.* Additionally, B. breve has been linked to helping with childhood constipation.* As children grow older and face health challenges, B. breve continues to bring strategic support: clinical research suggests this special bacterium is particularly effective in recolonizing the gut of children who have undergone chemotherapy.* The children who took this probiotic seemed to recover better from the treatment without any complications that are usually associated with chemotherapy.*

B. longum: One of the first bacteria to colonize our bodies at birth, Bifidobacterium longum has been associated with helping to digest milk and other challenging foods.* A placebo-controlled clinical study on 33 children with some digestive discomfort showed that in combination with a gluten-free diet, B. longum not only helped them grow taller, but also showed some indications of keeping their immune system strong and balanced.*

B. lactis: Bifidobacterium lactis is also powerful probiotic bacteria found in the digestive tract of humans. In one eye-opening study, when preterm babies were given B. lactis after taking antibiotics, they gained four times as much weight as the babies given the placebo.* In the same study, researchers observed signs that B. lactis helped the babies' immune systems develop effectively.* In addition, a meta-analysis of five studies revealed the role of B. lactis in supporting healthy weight gain may be particularly effective in the most vulnerable babies, as it seemed to help babies born to HIV positive moms gain much more weight per day than their counterparts who were not supplementing with a probiotic.* Finally, and significantly, preliminary lab research indicates B. lactis shows exciting promise in neutralizing certain toxins from wheat.*

L. gasseri: Lactobacillus gasseri is a normal inhabitant of the lower reproductive tract in healthy women. A clinical trial on children showed that this bacterium seemed to help regulate the immune system, as children who took L. gasseri showed an increase in regulatory T cell counts and a decrease in immunoglobulin E.* Preliminary research on mice indicates that L. gasseri may inhibit inflammation signaling at the genetic level.*

L. salivarius: Lactobacillus salivarius is a probiotic bacteria species that has been found to live in the gastrointestinal tract and exert a range of therapeutic properties including suppression of pathogenic bacteria.* Several clinical trials on both adults and children indicate that Lactobacillus salivarius seems to help regulate the immune system and, as a result, supports healthy skin.* L. salivarius also seems to play a distinct role in keeping the microbial population in the mouth healthy.*

Start low and slow: The digestive health supplements we carry are premium, pure and potent. Therefore, it’s critically important to start slowly, with a lower dosage than recommended. For example, a minimal dose every other day, or even once a week, until you can determine how the supplement affects your body and what feels right for you. 

How to take: Use our mini spoon set to accurately measure your desired dose of probiotic powder. You can sprinkle GutPro® Infant on lukewarm or cold food. Or it can be mixed in breastmilk, formula, a smoothie or organic milk of choice. For toddlers and older children, GutPro® Infant can also be taken with an organic fat, like butter, ghee, emu oil or coconut oil. See dosage instructions above for more info. 

Frequently asked questions

GutPro® Infant does not contain certain strains found in other probiotics that can cause histamine intolerance, d-lactic acidosis or other adverse reactions. This means no strains that produce d-lactate, no streptococcus thermophilus, no spore-forming strains; and only histamine-neutral and histamine degrading strains. It also does not contain prebiotics.

L. plantarum is omitted in GutPro® Infant because L. plantarum is a very potent strain that increases the potency of the formula. Because the folks at Organic 3 wanted the infant formula to be less potent than the original GutPro® powder, they did not include it. Customers with worries about d-lactate production may also prefer the omission of L. plantarum as it does produce a small amount of d-lactate. However, it’s important to remember that it helps balance the production of L-lactate. For more information about D-lactate free probiotics, click here.

There are no prebiotics in GutPro® Infant. This is because prebiotics like inulin and maltodextrin are often included in other commercial brands as fillers, yet can feed pathogens and cause negative reactions in people with sensitive digestive systems. Breast milk already has its own unique prebiotics. And prebiotics have been added to infant formulas with beneficial effects. But bottom line, Organic 3 wants parents to be able to carefully develop their children's diets according to their unique situations.

Yes! GutPro® Infant does not contain common additives, allergens or fillers. This means no excipients or other added ingredients, such as magnesium stearate, silica, titanium dioxide.

GutPro® Infant is free of common allergens. All strains are grown on a dairy-free, soy-free, vegetarian, non-GMO culture. GutPro® Infant does not contain milk/casein, eggs, fish, shellfish, wheat/gluten, peanuts, tree nuts, yeast, corn or soy.

GutPro® Infant is comprised of freeze-dried bacteria. Old school probiotics contained live cultures that died in transit due to warm temperatures. Freeze-dried bacteria can withstand warmer temperatures during transit.

The digestive probiotics in GutPro® powder work best in conjunction with a wholesome, real food diet for mother and children. Think healthy fats, organic or raw milk, wild-caught fish, grass-fed meat, organic vegetables; and the elimination of GMOs, additives, preservatives, chemicals and processed sugar/flour.

Note: Please consult with a qualified healthcare practitioner as to whether a probiotic is appropriate for your baby and when to start a regimen.
