Athlete’s Best™ Probiotic includes 18 beneficial strains of Lactobacillus, Bifidobacterium and Streptococcus cultures, including the clinically studied DE111® Bacillus subtilis strain. Our formula also features a synergistic prebiotic fiber blend to help with the overall absorption and bioavailability of the live cultures. Each vegan capsule guarantees at least 20 Billion Live Active Cultures (20 Billion CFUs). Most supplement companies state the amount of CFUs at The Time of Manufacture. We manufacture 35 Billion CFUs, so we guarantee our stated 15B per capsule for at least 3 years. Recommended dose is 1 capsule a day.

Why Choose Athlete’s Best™ Probiotics?

The human body is home to more than 100 trillion microorganisms, and due to a number of environmental factors, the “bad” bacteria typically outnumber the “good” bacteria 8:1, which leads to a host of health related issues. Probiotics featuring the strains carefully selected by our team help heal and restore the gut with “good” bacteria. A healthy gut flora aids digestion, protects from pathogens, improves the immune system, and helps with the absorption of vitamins and nutrients. These factors make a healthy gut flora absolutely essential for all athletes, and non-athletes alike.

Bacillus Subtilis DE111®

Multiple human clinical studies support this strain’s benefits for digestive and immune health, including supporting regularity, controlling microbial populations in the gut while optimizing digestion, and improvements in body composition, strength and recovery in athletes.


We’ve included 5 high quality strains of bifidobacterium into our blend including: Bifidobacterium bifidum, Bifidobacterium breve, Bifidobacterium animalis lactis, and Bifidobacterium longum. Bifidobacteria are among the best colonizers of the gut.


Our full spectrum probiotic is further enhanced by 10 beneficial Lactobacillus strains including: Lactobacillus acidophilus, Lactobacillus bulgaricus, Lactobacillus casei, Lactobacillus gasseri, Lactobacillus fermentum, Lactobacillus paracasei, Lactobacillus plantarum, Lactobacillus rhamnosus, Lactobacillus salivarius, and Lactococcus lactis.

Streptococcus thermophilus

This acid-resistant strain is one of the most effective at modulating the immune system, improving digestive health, and competing against unhealthy bacteria.

A Healthy Gut is Crucial to a Healthy Immune System
Athlete’s Best™ Probiotic is the Ultimate Addition to Your Health Regimen!

A healthy gut plays a very important role in nutrition and health. There is a delicate balance that exists between the intestinal microflora and its host. Due to different environmental factors, such as diet, medication, stress, age and overall living conditions, the gut microbiome becomes far out of balance.

Key Differences vs Other Brands

  • #1 – Potency Guaranteed at Consumption
    We guarantee at least 20 billion colony forming units at time of consumption (within 3 years of manufacture date), as we formulated the product with 35 billion CFUs at time of manufacture. Our latest batch available was manufactured on June 8th, 2020.
  • #2 – Pure Vegan
    Unlike most probiotics on the market, our product is 100% pure vegan.
  • #3 – Non GMO
    This is self explanatory, but there are absolutely no genetically modified ingredients within our product.
  • #4 – No Added Fillers
    You will not find any magnesium stearate or other unnecessary fillers within our Live-Source probiotic.
  • #5 – High Quality Strains
    Each strain contained within is of the highest quality available. Each strain provides specific benefits, versus just strains made to make the label better for marketing.
  • #6 – Delayed Release
    Most probiotic supplements on the market are completely useless. We have a delayed release so that all the strains make it to where they are needed – in the gut.
  • #7 – Live Source Ingredients
    Again, we use only highest quality live-source ingredients within our product.
  • #8 – State of the Art Testing
    We guarantee at least 20 billion CFUs at time of use. Most likely, you will be receiving more as our product was manufactured (potency verified) with 35B CFUs. We also have strict testing for contaminants and our product passes on all merits.
  • #9 – Solvent Free Plant Based Capsule
    Unlike most vegetable capsules, our capsules use absolutely no harmful solvents during manufacturing.

Consistency is Key.

For easiest convenience, take one vegetarian capsule daily between meals. One capsule a day should be sufficient as each capsule has a potency guaranteed 20 Billion Colony Forming Units within it. If you happen to experience any issues with bloating or gas, that should go away within a few days. Typically will take about 7-10 days for a probiotic to start working it’s magic within the gut.

All Athlete’s Best products are carefully sourced with the finest ingredients and rigorously tested for efficacy, purity, and safety.
