Approved Science® Probiotic - research drives results!

WHY CHOOSE APPROVED SCIENCE® PROBIOTIC

TO BOOST GUT HEALTH?

Most other probiotic supplements do not contain 10 different strands of live bacteria including  Saccharomyces boulardii which is a probiotic whose clinical efficacy, anti-inflammatory and immunomodulatory effects are supported by numerous clinical studies. Most don't provide a unique patented blend of probiotics such as Pro-Sci™. Most don't provide 25 Billion CFU (Colony Forming Units) which is key to providing effective results. The vast majority of positive clinical trials indicate that probiotic doses of 10-20 billion CFU per day are sufficient. Approved Science ® Probiotic understands the need for optimal strength so it included a significant CFU potency. Most do not contain a prebiotic which is the ultimate companion for a probiotic to ensure top quality results. The truth is that most probiotic supplements do not live up to their claims. Most do not have the potency needed. And most contain ingredients such as unnecessary proprietary blends, additives, preservatives, fillers or binders.

Due to extensive research and our firm understanding of what makes an effective probiotic supplement, we have created a product that is uniquely formulated to provide the ultimate support for the body to ensure a healthy gut and optimal health.

Each ingredient was carefully selected, based on years of research and clinical studies. Over 20 years of safety and efficacy research has been documented on what ingredients should be included in a quality probiotic supplement to get the very best results possible with absolutely no side effects.

Many studies document the positive benefits of probiotics, especially when taking antibiotics, to maintain balanced healthy bacteria in the body.

This top-quality vegan probiotic (with prebiotic) provides many incredible benefits: Balance, Support, Boost, and Maintain - supporting the body in a way that ensures your colon, GI tract and gut are functioning at their optimum level.

  • Balanced blue scales in a circle.

    STEP #1 BALANCE

    Studies show that a healthy balance of gut bacteria is essential for overall health. As we get older, the production of the healthy bacteria in the gut decreases, creating an imbalance. Antibiotics, stress, and poor diet can also create an imbalance. Probiotics provide the body with healthy bacteria and yeasts which restore the balance of the gut flora to ensure you stay happy and healthy.

  • Arrows pointing toward a stylized digestive tract.

    STEP #2 SUPPORT

    Probiotics support the body’s digestive and immune system to help protect against illness and disease. Supplementing with probiotics creates the optimal balance of gut flora which enhances digestion and the absorption of nutrients from food. It also helps fight inflammation and strengthens the immune system.

  • Stethoscope over intestines for digestive health.

    STEP #3 BOOST

    An imbalance of the bacteria in the gut has been linked to poor health. There are many microorganisms colonizing the GI tract, and as such, there are also many different strains of probiotics which provide different health benefits. Probiotics influence the gut flora and boost the number of healthy bacteria in the gut.

  • Blue bacteria shapes inside a circle.

    STEP #4 MAINTAIN

    To maintain optimal gut health, the correct strains of probiotics should be taken in the right amounts. The probiotics with the most health benefits include various strains of Bifidobacterium, Lactobacillus and Saccharomyces. Higher doses of these probiotics have been found to provide the best results for maintaining a healthy balance of gut flora and boosting health.
