Product Description

Introducing Smidge® Optimal Probiotic capsules, with 13 balanced, premium strains to give your overall digestive health lots of TLC. These strains work in synergy to help ease mild stomach issues, generate and maintain a healthy microbiome — and support reproductive and urinary health and a positive mood.*

We also curate and carefully calibrate each strain to maximize the benefits while avoiding side effects associated with other commercial brands, like d-lactic acidosis and histamine issues. This means your body can soak up the probiotic health benefits with ease, regularity and easy-breezy digestion.*

Of course, our Optimal Probiotic capsules are Non-GMO, free of common allergens, additives and other ingredients. And they’re made in small batches.

Dosage Directions

Adults: Always start with a smidge! Start with one capsule daily with food. Then take two capsules together, or as directed by a certified healthcare practitioner (see low and slow note below). 

Children: Take one capsule daily with food.

Sensitive individuals: For an even smaller dose, pull the capsule apart for only a portion of the powder.

Start low and slow: Our supplements 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: For best absorption, we recommend taking your probiotic with a meal or a spoonful of organic fat, like butter, ghee, emu oil or coconut oil. See FAQs for more info.

Storage

Smidge® Optimal Probiotic capsules require refrigeration for long-term storage. Keep away from moisture. Can be kept at room temperature for up to two weeks while traveling.

We prioritize sourcing the purest and most effective human-compatible probiotic strains:

  • We partner with renowned strain banks, bringing together decades of expertise.
  • Through meticulous genomic analysis, we verify the genetic integrity of each strain, selecting those with the most promising traits.

The process at Smidge® is just as thoughtful:

  • Our probiotic strains are cultured in carefully controlled environments, using non-GMO, organic plant-based sugars as growth nutrients.
  • We avoid common allergens, using a proprietary vegetable blend that excludes nightshades, root vegetables, and the Allium genus.
  • The probiotics are freeze-dried at collection to ensure potency.
  • Each batch undergoes thorough quality control and testing to confirm viability, safety and stability.

Why probiotics?

Probiotics are living organisms that reside deep within your gut. They help digest food, absorb nutrients and keep harmful microorganisms under control. If you don’t have enough good bacteria, it may become difficult for the body to fight pathogens. That’s why many folks supplement with probiotics with a bountiful, whole food diet. 

This rainbow of strains works together to nourish your inner ecosystem, all while being kind to your digestion. 

Optimal Probiotic health benefits 

Here are some potential benefits of the probiotics in this formula, based on research and studies*: 

  • A strong and well-regulated immune system: Probiotics support a vigilant immune system and help regulate immune response, as hundreds of studies show.* 
  • Comfortable and thorough digestion: Probiotics support a healthy digestive system and also play critical roles in helping your body break down and absorb nutrients. They even produce critical vitamins your body needs, like K2 and several B vitamins.* 
  • A strong gut lining: Probiotics can strengthen the gut lining and may protect the body from the effects of synthetic chemicals and pathogens.* 
  • A healthy urinary and reproductive tract: Healthy microbes in your urogenital tract can occupy space and produce chemicals that keep troublesome microbes in check, which may ease mild urinary irritation.* 
  • A sharp memory, steady concentration and an overall positive feeling: Research reveals these friendly organisms help your body produce neurotransmitters that shape how your brain grows and functions — to boost mood and ease stress response.* 
  • Seasonal allergies: Probiotics may ease itchy skin and mild hives, and one study shows that they may ward off mild allergies in adolescents.* Plus, they may help control blood cells related to mild allergies (the eosinophils level).* 
  • Dental health: Probiotics may help keep the microbial population in the mouth healthy, which means healthy teeth, fresh breath and a vibrant smile.* 
  • Skin issues: Probiotics help balance the skin microbiome and therefore may contribute to a healthy complexion, and ease mild rashes and mild fungal issues.* 
  • Mild candida/yeast overgrowth: Probiotic strains may ease mild yeast infections and help avoid them when taken regularly, according to recent studies.* 

Stable and pure formula

Like all of our probiotic formulas, Optimal Probiotic is cGMP certified to ensure product stability and purity. And the hardy strains are resistant to low Ph conditions in the tummy, meaning they’re genetically characterized to pass through your gut safely and can withstand stomach acid and bile, so they can do their essential job. 

Our entire detailed approach ensures that every batch of Smidge® probiotics is rooted in scientific precision and natural goodness – providing clean, reliable support for digestive health. So you can trust you're giving your family the very best.

Frequently Asked Questions

Which probiotic should I take?

 

There are so many fantastic options! Here's how we break it down:

  • Infant Probiotic: Our Infant Probiotic powder is recommended for anyone under the age of 2. However, because it's such a gentle formula, it's also ideal for sensitive individuals of all ages, or those taking probiotics for the first time. It's our least potent formula. The Infant Probiotic contains seven clinically-proven strains of beneficial bacteria naturally found in the digestive system of a healthy infant, and comprises 50% Bifidobacterium infantis. This strain is special because it dominates in breastfed babies' intestines, as it thrives on a unique molecule from breast milk. In scientific studies, B. infantis has been linked to healthy digestion, growth and immunity in infants.*
     
  • Sensitive Probiotic: The Sensitive Probiotic powder is best for ages 3 and over, or children between the ages of 2 and 3 who have already used the infant formula. It contains one extra strain (L. plantarum) and is twice the potency of the Infant Probiotic. Smidge® Sensitive Probiotic is a powerful formula that does not require large doses. However, it's suited for sensitive individuals who may have reacted to certain strains of bacteria found in other probiotic formulas. Many of our customers with histamine intolerance, digestive issues, skin problems and other health conditions begin with our Sensitive Probiotic powder. In all, it's for those who are serious about gut health: a clean, potent, therapeutic-grade probiotic with eight strains of beneficial bacteria that are essential for digestive health, and no additional ingredients. This product is also available in capsules.
  • Optimal Probiotic capsules: Smidge® Optimal Probiotic is a gentle, thoughtfully formulated probiotic that’s appropriate for various ages and stages, whether you’ve taken probiotics in the past or are new to this integral part of your wellness regimen: 
    • Men and women: Teens through the golden years,
    • Mamas: Pregnant and nursing,
    • Healthy kiddos: Ages 6 to 12.
  • Yeastbiotic: Our Yeastbiotic capsules feature the friendly yeast Saccharomyces boulardii, which can gently crowd out pathogenic yeast.* S. boulardii is clinically proven to support people during antibiotic treatment, especially with candida, diarrhea and C. diff, as guided by a healthcare practitioner.* And you don't have to worry about it affecting your antibiotics. Most people use this one on a short-term basis.

Please keep in mind that the age to progress from one formula to another for every person varies. Since everyone is unique and responds differently to different formulas, it's important to consider the individual's health history, diet, metabolism, and recommendations by a practitioner — not just age. And our customer service team is here to answer your questions :) 

Can you ship Smidge® Optimal Probiotic capsules in hot temperatures?

 

Yes. Smidge® Optimal Probiotic capsules (and all of our probiotics!) can be shipped when it's hot outside. Because it requires refrigeration, we only ship orders Monday through Wednesday using two-day premium shipping services that include tracking. We also have an overnight shipping option.  

Smidge® probiotics are freeze-dried, so they hold up well to warm temperatures. 

What is the best time and way to take my Optimal Probiotic capsules?

Here's the fun part. We recommend taking your probiotic with a meal or directly before the meal (around the same time daily). It's beneficial if the meal also contains some natural, organic fat or oil.    

Taking your probiotic with yummy food provides a buffering system for the supplement and ensures its safe passage through the digestive tract. Food also provides the friendly bacteria in your probiotic with the proper nourishment to ensure its survival in your gut. 

Our probiotics work best with an ancestral diet: unprocessed foods (meat, vegetables, fruits), healthy fats (olive oil, butter, lard, coconut oil, etc.) and no grains (i.e., no wheat, corn, rice, etc.). 

Please avoid taking probiotics with certain foods that may diminish the potency: 

  • Avoid chlorinated water.
  • Avoid hot soup and hot beverages (coffee, tea, etc.).
  • Avoid highly processed foods (store-bought juice, sugar, wheat and soy products).

How many strains does this formula have?

Lots! Our Probiotic capsules contain 13 clinically-proven probiotic strains; 12 human strains and one plant strain (L. rhamnosus, L. casei, L. acidophilus, L. paracasei, L. brevis, L. gasseri, L. salivarius, B. bifidum, B. breve, B. infantis, B. longum, B. lactis and the plant strain, L. plantarum). 

We use only the highest-quality probiotic bacteria: All strains have been thoroughly researched, documented and banked in recognized microbial culture collections. And, our strains are non-GMO and tested for purity.

Is this Optimal Probiotic free of common allergens?

Absolutely. Our Optimal Probiotic capsules are free of common allergens. All strains are grown on a dairy-free, soy-free, vegetarian, non-GMO culture. The product does not contain milk/casein, eggs, fish, shellfish, wheat/gluten, peanuts, tree nuts, yeast, corn or soy. 

Does this probiotic contain prebiotics?

 

Nope. Most commercial probiotics are up to 80% prebiotics. This is notable because adding prebiotics reduces the potency of a probiotic supplement and therefore, reduces the cost per bottle. More importantly, we intentionally keep prebiotics out of our probiotic formulas, as many of our customers have extremely sensitive digestive systems or are biohackers who only want purity. 

A probiotic can work alone and does not require a prebiotic. Our pure probiotics can colonize without a prebiotic. 

Plus, not all people taking a probiotic need a prebiotic. In fact, we recommend starting our probiotics without a prebiotic, before determining whether or not to add it to your protocol. We believe it's important to focus on diet and real food to support the colonization of good gut bacteria and starve off pathogens. 

Here's some additional background regarding our philosophy on prebiotics: Most commercially available prebiotics are made from FOS/inulin. This starchy, sugary substance can feed pathogens like E. coli and many Clostridium species, which would be counterproductive to gut health and overall health. There's also a concern that some kinds of yeast are able to use inulin/FOS for fuel, thereby leading to overactive yeast production in the body. 

Where are the ingredients in Smidge® Optimal Probiotic sourced and where is the supplement made?

 

The strains in our Optimal Probiotic capsules are sourced U.S., as is the production of the final product :) 

What kind of diet should I eat while on Smidge® Optimal Probiotic capsules?

 

Our probiotics and supplements work best in conjunction with a wholesome, real food diet. Think healthy fats, wild-caught fish, grass-fed meat, organic vegetables, and the elimination of GMOs, additives, preservatives, chemicals and processed sugar/flour. So eat clean and eat up! 

 

Can this probiotic formula withstand stomach acid?

Yes! Plus, like all of our probiotic formulas, it’s cGMP certified to ensure product stability and purity. The hardy strains in our Optimal Probiotic are resistant to low Ph conditions in the tummy, meaning they’re genetically characterized to pass through your gut safely and can withstand bile, so they can do their very important job.

    Changing Probiotic for Changing Needs

    We had been taking Sensitive Probiotics Powder for years, but as we age research is showing that probiotics affect nutrient absorption in the gut. Since that can become an issue as we age, we decided to step up our game, and we can feel the difference, all else being equal. Thanks, Guys!!

We’re thrilled to hear that you've felt a positive difference after making the switch—especially as you prioritize your gut health and nutrient absorption. As we age, supporting digestion becomes more critical, and it’s fantastic that Smidge® is helping you step up your game! Wishing you continued health and happiness!

    Hugely supportive

    I took the Sensitive for a while (on and off for years and then more consistently for a few months), before starting with small amounts of the Optimal sprinkled in. Now taking full capsules and experiencing gentle soothing and vitalizing of the gut, which in turn supports so many other systems/processes. Great product.

    Hi Linda, Thanks for leaving a 5-star review on our Optimal Probiotics. We appreciate you sharing this feedback. Some folks ask why our products cost what they do. We craft our probiotics and other supplements in small batches for freshness (rather than mass-produced) and with the most premium, clean ingredients possible, which also comes at a higher cost. We want to assure you that we do all we can to keep our prices manageable, and to make pure, small-batch supplements an accessible part of your wellness routine. Our manufacturing partners have raised the prices several times in the past and we try to cover them as best we can for our customers. Once again thank you for supporting Smidge®!
