Designed for Men

We took this formulation a step further by adding a blend of ingredients generally known to support men's overall health. Specifically, these probiotics work to support men's reproductive function, testosterone levels, athletic performance, a healthy digestive system, immune system health† and more.


Many probiotic strains are fragile and require refrigeration to survive. Even when you take them, they may not all make it into your gut to colonize. SBOs are resistant to extremes in temperature as well as the harsh environment of the digestive tract. These strains are tough and survive without refrigeration.

Trifecta Effect

SBO Probiotics offer a trifecta approach in its formulation for prebiotic, probiotic and postbiotic support setting the stage for, with and following the SBO Probiotics. Probiotics are the good guy bacteria in our bodies. Prebiotics, however, act as fertilizer for probiotics and are typically non-digestible fiber compounds that help probiotics thrive. This formula combines specially selected ingredients chosen by our formulators Jordan Rubin and Dr. Axe like an organic mushroom blend and an organic fermented botanical blend. The Organic Mushroom Blend has properties that can help foster prebiotics while the organic fermented botanical blend has prebiotic superfoods to help set the stage for the soil-based organisms.

Diverse Probiotic Strains

This probiotic blend features 4 diverse strains and 25 billion CFUs.* It includes an SBO beneficial yeast and 3 SBO Bacilli (beneficial bacteria) strains.

Frequently Asked Questions

Frequently Asked Questions

Dr. Axe Answers

Ancient Nutrition co-founder, chiropractor, clinical nutritionist and certified doctor of natural medicine is here to answer your questions!

What does Bacillus subtilis do?

In general, Bacillus subtilis can manage the harsh stomach acid environment, allowing it to get to the digestive system and colonize its beneficial bacteria. Bacillus subtilis is truly a hardy, tough probiotic that is resilient and highly adaptable.

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?

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 of 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% percent 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.

What is the right amount of CFUs to be getting every day?

It varies. For most people, I recommend a CFU count anywhere between 25 to 100 billion. This probiotic formula features 25 billion CFU* per serving. *at time of manufacture

What should I look for in a gut supplement?

There are four specific things to consider when selecting a probiotic supplement:
1. SBOs and Shelf-Stable: Make sure your probiotic supplement includes soil-based probiotics (SBOs) and is shelf-stable, meaning it doesn't need to be refrigerated. While it might seem odd to eat dirt

What other key ingredients set this probiotic apart from others?

In addition to the organic fermented botanical blend, this formula includes a blend of ingredients generally known to support general wellbeing like zinc, selenium, organic ashwagandha and a unique blend of mushrooms.

What is the complete list of organic botanicals in this product?

One of the premium features of SBO Probiotic is its botanical blend that includes:

  • Organic ginger (root)
  • Organic fenugreek seed
  • Organic fo-ti root he shou wu

How is this product different from the probiotics in your Ancient Probiotics line?

The main difference is that this SBO Probiotics formula features primarily soil-based, spore-forming organisms, and Ancient Probiotics features mostly non-spore forming cultures.

The strains in SBO populate differently in your gut than the live cultures in Ancient Probiotics, so they are great to take together for more strain diversity.

SBO Probiotics feature a fermented botanical blend of prebiotics, while Ancient Probiotics do not. Ancient Probiotics feature Ayurvedic herbs; SBO Probiotics does not feature these.

Ancient Probiotics varieties feature anywhere between 25 billion and 100 billion CFU* per serving, and SBO Probiotic- Men's features 25 billion CFU* per serving.

Soil-based organisms are generally more survivable than live cultures, which is why there are 16-17 strains of probiotics in Ancient Probiotics and four strains in SBO Probiotics. *at time of manufacture

Is this dairy-free?

These probiotics are made without dairy - we removed the Lactobacilli strains found in our classic SBO Probiotic formulation.

Generally, what makes soil-based probiotics different from other types of bacteria and yeasts?

Soil-based organisms are often stronger than other forms of bacteria since they don't require refrigeration (meaning they're shelf-stable) or any special handling. They can generally survive the journey through the stomach to the intestines.

Soil-based organisms are typically able to seed the digestive tract with beneficial bacteria which can grow and flourish to support health, including supporting healthy digestion and a healthy immune system.†
