We have the answers to your Gut Health

How often should we take probiotics?

Several lifestyle factors may disrupt and weaken your intestinal flora. However, regularly consuming a quality probiotic product may help in this regard. Moreover, beneficial bacteria may help digestion by secreting enzymes. You can take our capsules and even our drinkable probiotics on a regular basis to support your gut microbiome. You can also take it a few times a year when you need it the most!

Is it possible to take in too many probiotic bacteria?

It's always recommended to consult a health care professional before using a new supplement such as probiotics. In theory, you can not take too much probiotics, the intestinal transit should eliminate unnecessary bacteria. Our bacterial strains are transient and don't stay in the gut for a long period of time. However, it's always better to start the intake of probiotics more gradually and monitor your wellbeing. Benefits of Bio-K+ will take place in the intestines to support the gastrointestinal health. The number of probiotics contained in a product is specific to the strains included and is a key, but not the only factor to take into consideration while to supporting wellbeing.

What criteria are used to determine a probiotic’s effectiveness?

Here are some useful tips on how to identify an effective probiotic: 1. Identifiable high quality strains: On all Bio-K+ products, you will find the strains used in the product clearly identified on the packaging. Our patented formula, for the majority of our products, contains 3 strains: L. casei LBC80R(R), L. rhamnosus CLR2(R) and L. acidophilus CL1285(R) 2. Synergy between the strains: Most of the Bio-K+ products contain these three patented strains that ferment together, demonstrating strong synergy in the finished product. 3. Guaranteed bioactivity: The bacterial count of the Bio-K+ products is guaranteed until the expiration date or best before date. 4. Gastrointestinal survival: Bio-K+ capsules use targeted-release technology to protect bacteria from stomach acidity. The bacteria in our drinkable probiotics are active and alive, they are also safeguarded by a nutrient-rich environment. 5. Clinical studies on the finished product: The efficacy and safety of our probiotic strains in finished products are supported by several peer-reviewed clinical studies.
