What Probiotics Are in Bio K? Unpacking the Key Strains and Benefits

4 min read

According to Bio-K+, its patented probiotic formula is powered by a proprietary trio of clinically studied strains, setting it apart from many other multi-strain supplements that may not demonstrate the same level of synergy. This unique combination is the foundation for the product's benefits, which have been proven to support digestive and overall gastrointestinal health.

Quick Summary

Bio-K+ products contain a proprietary blend of three probiotic strains: Lacticaseibacillus casei LBC80R, Lacticaseibacillus rhamnosus CLR2, and Lactobacillus acidophilus CL1285. This combination is designed to work synergistically to support digestive and immune health, with products available in both drinkable and capsule formats.

Key Points

  • Core Strains: Bio-K+ features a proprietary blend of three main probiotic strains: Lacticaseibacillus casei LBC80R®, Lacticaseibacillus rhamnosus CLR2®, and Lactobacillus acidophilus CL1285®.

  • Synergistic Action: The three strains in Bio-K+ are fermented together to work synergistically, which enhances their effectiveness compared to products with many competing strains.

  • Format Variations: The probiotics are available in both ready-to-drink fermented products and delayed-release capsules, catering to different consumer needs and preferences.

  • Guaranteed Potency: Unlike some brands that measure CFU at the time of manufacture, Bio-K+ guarantees the number of live bacteria until the product's expiry date.

  • Clinical Evidence: The efficacy and safety of the finished Bio-K+ products have been supported by numerous peer-reviewed, double-blind, placebo-controlled clinical trials.

  • Immune Support: The strains contribute to strengthening the immune system by bolstering the intestinal barrier and promoting a healthy gut microbiome, where a significant portion of the immune system resides.

The Synergistic Trio of Probiotic Strains in Bio-K+

Unlike many probiotic supplements that contain a vast number of different bacterial strains, Bio-K+ emphasizes a synergistic approach by focusing on a specific blend of three proprietary strains. The company has invested decades into researching the optimal interaction of these bacteria to provide targeted health benefits. This exclusive formula features Lactobacillus acidophilus CL1285®, Lacticaseibacillus casei LBC80R®, and Lacticaseibacillus rhamnosus CLR2®, which work together to support the gut microbiome. The intentional selection and fermentation of these three specific strains ensures their efficacy, as demonstrated by clinical studies on the finished product.

The Role of Lactobacillus acidophilus CL1285®

This strain is included in the Bio-K+ formula to help maintain a healthy balance within the gut. Lactobacillus acidophilus CL1285® works by creating an environment unfavorable to the overgrowth of potentially harmful bacteria. By helping to keep 'bad' bacteria at bay, it supports the overall balance of your intestinal flora, contributing to better digestive function and a healthier gut environment.

The Function of Lacticaseibacillus casei LBC80R®

As part of the Bio-K+ blend, Lacticaseibacillus casei LBC80R® plays a crucial role in maintaining gut integrity and bolstering the immune system. A strong, healthy gut lining is vital for preventing unwanted substances from entering the bloodstream, a condition sometimes referred to as 'leaky gut'. This strain helps to reinforce the gut barrier, contributing to the body's natural defense system. Its immune-supporting properties are part of the reason Bio-K+ is often recommended by healthcare professionals.

The Impact of Lacticaseibacillus rhamnosus CLR2®

Another key component, Lacticaseibacillus rhamnosus CLR2®, helps cultivate a friendly environment that encourages the growth of beneficial bacteria. This strain is known for its ability to support the digestive and immune systems. By creating a welcoming habitat for good bacteria, it helps the microbiome flourish and perform its essential functions, which include nutrient absorption and the synthesis of certain vitamins.

How the Bio-K+ Strains Deliver Results

The synergistic action of these three strains is a key differentiator for Bio-K+. While many probiotics may have higher total CFU counts, the research-backed combination of L. acidophilus CL1285®, L. casei LBC80R®, and L. rhamnosus CLR2® is designed for specific efficacy. This approach ensures that the bacteria work together rather than competing, maximizing their health benefits. The company also employs specific delivery methods, such as enteric-coated capsules and nutrient-rich drinkable formulas, to ensure the live bacteria survive the journey through stomach acid and reach the intestines where they can be most effective.

Bio-K+'s Commitment to Quality

Bio-K+ adheres to five quality criteria that have guided its product development for over two decades. This commitment helps ensure that consumers receive a potent and effective probiotic.

  • Identifiable High-Quality Strains: The specific strains used are clearly identified on every product package.
  • Synergy between the Strains: The three patented strains are fermented together to ensure they work synergistically.
  • Guaranteed Bioactivity: The bacterial count is guaranteed to be active until the expiry date, not just at the time of manufacture.
  • Gastrointestinal Survival: Special delivery methods, like targeted-release capsules, protect the bacteria from stomach acidity.
  • Clinical Studies on the Finished Product: The efficacy and safety of the specific Bio-K+ formulation have been demonstrated in peer-reviewed clinical studies.

A specific IBS-focused product has also been formulated with the same three strains to help normalize bowel habits and relieve digestive discomfort for individuals with diarrhea-predominant irritable bowel syndrome. This scientific support helps distinguish Bio-K+ within the competitive probiotic market.

Conclusion: A Focused and Clinically Supported Approach

Bio-K+ distinguishes itself in the probiotic market by concentrating on a proprietary blend of three specific, synergistic strains: Lactobacillus acidophilus CL1285®, Lacticaseibacillus casei LBC80R®, and Lacticaseibacillus rhamnosus CLR2®.
