Lactobacillus Reuteri 50B CFU – 60 DR Capsules | With Prebiotic FOS | Made in Canada

What Is Limosilactobacillus reuteri?

Limosilactobacillus reuteri (formerly classified as Lactobacillus reuteri) is a naturally occurring lactic acid bacterium that has been more extensively researched than most probiotic strains on the market. The LR08 strain used in Herba® Lactobacillus Reuteri 50B is a well-characterized, whole-cell isolate selected specifically for its stability and established research profile.

Unlike many probiotic supplements that deliver modest doses, Herba® Lactobacillus Reuteri 50B provides 50 billion CFU per capsule — a high-potency amount that goes well beyond the 1–10 billion CFU found in most entry-level products. CFU count is a primary determinant of how many viable organisms actually arrive in the gut, making this distinction meaningful.

Why Delayed-Release Capsules Matter

Most standard capsules dissolve in the stomach, exposing probiotic bacteria to harsh gastric acid before they can reach the intestines. Our pharmaceutical-grade DR (delayed-release) vegetable capsules are engineered to resist that acidic environment and release their contents further along the digestive tract — precisely where probiotics need to be to do their work.

This targeted delivery means a significantly greater proportion of the 50 billion CFU survives transit compared to a standard-release capsule at the same dose. For a probiotic supplement, how it's delivered is just as important as what's inside.

The Role of Prebiotic FOS

Each capsule also includes fructooligosaccharides (FOS), a naturally derived prebiotic fibre that acts as a food source for beneficial bacteria. By pairing L. reuteri with FOS in a single capsule, our formulation supports both the delivery and the sustainability of probiotic activity in the gut.

Shelf Stable — No Refrigeration Required

Herba® Lactobacillus Reuteri 50B is shelf stable at room temperature, making it practical for everyday use and travel. Stability is supported through careful encapsulation and the inclusion of ascorbyl palmitate, a fat-soluble antioxidant that helps protect live cultures during storage.

Warnings:

Do not use this product if you have an immune-compromised condition (e.g. AIDS, lymphoma, patients undergoing long-term corticosteroid treatment).

Stop use and consult a health care practitioner if symptoms of digestive upset (e.g. diarrhea) occur, worsen and/or persist beyond 3 days.

Q. What is the difference between Limosilactobacillus reuteri and regular Lactobacillus strains?
A. Limosilactobacillus reuteri (formerly Lactobacillus reuteri) is a distinct probiotic species with its own unique properties and a notably deep research history compared to many common Lactobacillus strains. The LR08 strain in Herba® Lactobacillus Reuteri 50B is a specific, well-characterized whole-cell isolate chosen for this formulation for its stability and documented profile.

Q. What are delayed-release (DR) capsules and why do they matter for probiotics?
A. DR capsules are designed to resist dissolving in the acidic stomach environment and instead release their contents in the intestines. Since most probiotic strains are sensitive to stomach acid, DR capsules help ensure a significantly greater number of live CFU survive transit and arrive where they can be effective — unlike standard capsules that dissolve before reaching the gut.

Q. How do I take Herba® Lactobacillus Reuteri 50B?
A. For ages 6 and older: take 1 capsule once per day. If you are taking antibiotics, take this product at least 2–3 hours before or after your antibiotic dose to avoid interference with the live cultures.

Q. Is this product vegan and allergen-friendly?
A. Yes. Herba® Lactobacillus Reuteri 50B is vegan, non-GMO, and gluten free. The capsule shell is made from hypromellose (vegetable-derived), and all non-medicinal ingredients — ascorbyl palmitate, cellulose, fructooligosaccharides, hypromellose, and l-leucine — are free of animal-derived ingredients.

Q. Does this probiotic need to be refrigerated?
A. No refrigeration is needed. The formula is shelf stable at room temperature, making it convenient for daily use at home or while travelling.

Q. What does 50 billion CFU mean?
A. CFU stands for Colony Forming Units — a measure of the number of viable, live microorganism cells in each capsule. 50 billion CFU is a high-potency dose; many standard probiotic supplements contain only 1–10 billion CFU per serving. A higher CFU count means more live organisms are available to survive transit and reach the gut.

Q. What is an NPN and what does it mean for this product?
A. NPN stands for Natural Product Number. It is a licence issued by Health Canada confirming that the product has been reviewed for safety, efficacy, and quality under Canadian natural health product regulations. Herba® Lactobacillus Reuteri 50B holds NPN 80142896, meaning it is a fully licensed natural health product in Canada.

Q. Is this product third-party tested?
A. Yes. Herba® Lactobacillus Reuteri 50B is third-party tested for purity, heavy metals, and microbial safety, and is manufactured following cGMP standards.
