Key Ingredients
Nearly 80% of your immune system health lives in your gut. That’s more than enough reason to nourish your microbiome on a daily basis. That’s why we use some of the most resilient probiotics on the planet – soil-based organisms (SBOs) – that are designed to thrive in harsh environments like the high temperatures and stomach acids they meet in our digestive tracts.

Clinically Studied SBO Probiotics
Each serving delivers 50 billion CFUs* (*at time of manufacture) of clinically studied probiotics, including Saccharomyces boulardii and three resilient soil-based organisms (SBOs): Bacillus clausii, Bacillus coagulans, and Bacillus subtilis. Unlike typical probiotics, SBOs are tough, shelf-stable, and built to thrive in your gut—no refrigeration needed.

Prebiotics & Postbiotics
We take a trifecta approach to gut health by pairing clinically studied probiotics with prebiotics and postbiotics. Prebiotics act as fuel for probiotics, and postbiotics are the metabolites (enzymes and organic acids) that are created by probiotics. Together, they provide powerful support for digestive health.

Superfood Support
Designed for ultimate gut support, this SBO probiotic formula brings you diverse superfoods like organic fermented ginger root, turmeric root and black pepper fruit (all used for centuries to support optimal gut health). Fermentation works to unlock important nutrients and compounds within the ingredient, which helps make it easier for your body to absorb — so you’re getting more out of the supplements you’re taking.

FAQ
What do each of the probiotic strains do?
What do each of the probiotic strains do?
Bacillus coagulans is an incredibly resilient SBO probiotic strain that is actually activated in the harsh, acidic environment of the stomach. It helps support gut function and reduces occasional gas, bloating and constipation, as well as helps maintain healthy gut microflora, healthy bowel transit time† and more.
Bacillus subtilis is naturally found in the environment and plants. It’s a tough strain that helps support a healthy immune system and inflammation response.†
Bacillus clausii, like the other strains, has the unique ability to withstand harsh environments that other probiotics can’t. It’s been used in Europe for over fifty years and helps to support digestive health.
Saccharomyces boulardii is actually a yeast, but it acts as a probiotic. It helps support a healthy immune system, regular bowel function† and more. It’s also one of the few yeasts that survives best at human body temperature, giving it the capacity to thrive in the gut.
Do I need to refrigerate these probiotics?
Do I need to refrigerate these probiotics?
Our SBOs arrive dormant and are stable at room temperature, without refrigeration.
Why should I give my gut support?
Why should I give my gut support?
Fact: Most Americans don't consume enough probiotics in their diet due to modern processed foods, soil depletion and more. I believe most people are in need of probiotic support.
Here's why: Thanks to prescription antibiotics, high carbohydrate diets, fluoridated tap water and high levels of stress, the good bacteria in our guts are often diminished, and our bodies can't replace them at the rate required for optimal health.
Many probiotics health benefits are gut- and digestion-related, so here are a few key reasons why gut health, in general, is so important to overall health:
- Up to 80% of the immune system is housed in the gut.
- Between 80% to 90% of the body's serotonin, often referred to as a feel good or happy chemical which acts as a neurotransmitter, is found in the gut. Serotonin is thought to have many effects on the body, including the areas of digestion, sleep, memory, behavior and more.
- Every bodily cell, tissue and organ depend on proper nutrient absorption and assimilation of food through healthy digestion, and, generally speaking, probiotics can play a supporting role in that.
When will I start to notice a difference?
When will I start to notice a difference?
Everyone is different, and will have a different experience when using the products. We suggest giving any new product a chance for 90 days. However, some people will experience digestive support soon after they start.
What is the right amount of CFU's to be getting every day?
What is the right amount of CFU's to be getting every day?
It varies. For most people, we recommend a CFU count anywhere between 25 to 100 billion. Our SBO Probiotics Ultimate features 50 billion CFUs* per serving. Our other SBO Probiotics capsules feature 25 billion CFUs* per serving, and the SBO Probiotics gummies features 10 billion CFUs* per serving.

When is the best time to take probiotics?
When is the best time to take probiotics?
To help support absorption and colonization in the gut, we recommend taking probiotic capsules (or gummies) on an empty stomach, either when you first wake up or right before bed (roughly 2–3 hours after your last meal).
