Of course, an overall healthy diet and lifestyle are the cornerstones of health, but these one-of-a-kind probiotic formulas are made to survive and help you thrive. Because we all know immune system health is tied to gut health, Ancient Nutrition’s SBO Probiotics are made with soil-based organisms, probiotics naturally suited to survive the harsh journey to your gut — where they can really unpack the benefits. After all, up to 80% of the body’s immune system cells are found in the gut.

Our co-founders formulated SBO Probiotics using a “trifecta” approach, harnessing the complementary power of prebiotics, probiotics and postbiotics. Together, they supply the healthy gut, healthy immune system and overall support you deserve.


The human body is typically 98.6 degrees. That means you need a probiotic built to take the heat. SBO Probiotics feature a natural “shell” that makes them resistant to heat and stomach acid, so the beneficial bacteria actually makes it to your gut. The best part? They’re shelf stable — no refrigeration required.

CFU & Strain Diversity

Our SBO Probiotics line contains between 25 and 50 Billion CFUs* per serving (*at time of manufacturing), depending on the formula you choose. While SBOs can be taken in supplement form, they’re naturally found outdoors in the soil. These are the same strains your grandparents and ancestors ate when they’d enjoy fresh veggies from the garden. For purity and safety, though, the probiotic, “good guy” gut bacteria cultures found in our SBO Probiotics are lab grown.

Trifecta Approach

We used a 3-prong approach to formulation, including prebiotic, probiotic and postbiotic support. Probiotics set the stage for the SBO probiotics to get to work, “feeding” the probiotics to help amplify wellness properties. Our unique organic blend or fermented, sprouted seeds serve as a postbiotic support system, offering organic acids, carbonic substances and enzymes round out our “trifecta” digestive support tag team.

SBO Probiotic Ultimate

Our “Ultimate” Probiotic delivers our highest CFU count at 50 billion, giving you high-quality gut and immune system health support.† Designed to promote proper digestion and nutrient absorption and a healthy inflammation response† , Ultimate also helps reduce occasional diarrhea, constipation, gas and bloating.†

SBO Probiotic Women’s

By a woman's very design and function, digestive needs are often different than men's. In fact, structurally, the "pathway" of certain areas of women's digestive systems can be more complex than a man's. This unique formula is created with a woman's special needs in mind, including an organic, fermented botanical blend featuring alma berry and chaste tree berry, an organic mushroom blend and clinically studied ashwagandha, an herb known to promote reduced stress and a positive mindset.† All that and the healthy immune system and digestive health support and relief from occasional bloating† all of our SBO Probiotics ensure.
