Frequently Asked Questions

What should I look for when choosing a probiotic capsule?

Look for probiotic capsules that identify the full strain designation on the label: genus, species, and strain code, since clinical benefits are strain-specific, not genus-level. Look for a CFU count guaranteed until the expiration date, not at the time of manufacture. Confirm the capsule shell and all ingredients are free from animal-derived materials if vegan compatibility matters. Prioritize a probiotic capsule backed by published clinical studies conducted on the finished formulation, not on individual isolated strains

Does the CFU count on a probiotic capsule label tell me how many bacteria will reach my gut?

CFU, or colony-forming units, indicates the number of live bacteria per dose at a given point in time. Labels listing CFU "at time of manufacture" may not reflect the live bacterial count by the time you use the product, since bacteria counts decline during shelf life when storage conditions fail to maintain potency. For a meaningful potency figure, look for probiotic capsules that guarantee their CFU count until the expiration date. Probiotic capsules with this guarantee provide transparency about potency at the time of use. The CFU count does not indicate whether the bacteria reach the intestines. Protection is necessary, such as delayed-release technology.

Should probiotic capsules be taken with food?

Bio-K+ capsules can be taken any time of day, with or without food. For the best results, take them at the same time daily so consistency becomes part of your routine. When you are deciding when to take probiotic capsules, the timing matters less than the habit. One thing to keep in mind about taking probiotic capsules with food: do not open the capsules, and do not mix them into warm dishes or cook them, since heat can affect the live bacteria inside.

Can probiotic capsules be opened and mixed into food or a drink?

No. Bio-K+ capsules should not be opened. Each one uses delayed-release technology designed to survive gastric acid and reach the gut intact, so opening a probiotic capsule works against that design. Mixing a probiotic capsule into food or a drink can also expose the live bacteria to heat, acidity, or air before they arrive where they are meant to. To get the full benefit, swallow each capsule whole with water.

Where are Bio-K+ probiotic capsules manufactured?

Bio-K+ manufactures its probiotic capsules at its own facility, from strain cultivation through final packaging. This vertically integrated approach allows Bio-K+ to maintain close control over quality at every step, from growing the bacterial strains to the final product. The Bio-K+ probiotic strains have been studied for more than 30 years and are supported by over 45 peer-reviewed publications and 16 published clinical trials conducted by both internal and external research partners.

What's the difference between Bio-K+ probiotic capsules and probiotic drinks?

Both formats deliver the same three clinically studied strains. Drinkables are live and active immediately, working through the upper and lower GI tract as you consume them. Capsules use freeze-dried, dormant bacteria released through delayed-release technology in the intestines. If you're deciding between probiotic capsules and drinks, capsules are a practical option for travel or for anyone new to probiotics who wants a simple, portable daily format.

I recognize signs I might need a probiotic — which capsule should I start with?

A general-purpose, standard-potency capsule is a sensible starting point rather than a condition-specific formula. These daily probiotic capsules use Bio-K+'s three-strain, delayed-release technology and promote digestive and immune health.† For anyone wondering which probiotic capsule to start with, a standard daily option fits most everyday routines. If your signs feel severe or persistent, consult a healthcare professional before choosing a specific product.

If I start with capsules, can I switch to a drinkable later?

Yes. Capsule vs. drinkable probiotics both deliver Bio-K+'s same three-strain formula, so switching probiotic formats doesn't mean switching formulas. The choice comes down to what fits your routine, not which is more effective. Capsules offer shelf-stable options, while drinkables provide live and active bacteria from the first sip and promote digestive and immune health.† Either format supports the same consistent daily approach.
