Probiotic Capsules

Bio-K+ probiotic capsules do not require refrigeration to maintain their bacterial count. The potency is guaranteed until the expiry date at room temperature. The desiccant sachet inside every bottle keeps the capsules dry and stable throughout a trip. While refrigerating capsules at home can help maximize longevity, it is not required for the potency guarantee. This makes them practical to pack in carry-on or checked luggage without needing a cooler or hotel fridge.

The On-the-Go Capsules (30B CFU per capsule) are specifically positioned for high-potency on-the-go support. They contain the same three exclusive strains as the rest of the capsule lineup and are shelf-stable without refrigeration. For those newer to probiotics, starting with the Daily Care capsules (12.5B CFU) or Daily Care+ (25B CFU) and increasing potency as needed is a practical approach. All three options are vegan, gluten-free, and free from major allergens.

Capsules and drinkable probiotics use the same three-strain probiotic formula and are equally effective at helping to support gastrointestinal health. The practical difference for travelers is storage: capsules are shelf-stable and require no refrigeration, making them easier to pack and carry. Drinkable probiotics must be kept refrigerated, or are limited to 24 hours unrefrigerated, and come in bottles that can be less convenient for transit. Capsules are often preferred for travel precisely for this reason.

Research into the gut health and mental wellness shows that supporting a balanced gut microbiome may play a role in how the body responds to everyday stress. Approximately 90% of the body's serotonin is produced in the digestive tract, and gut bacteria are involved in neurotransmitter production that contributes to emotional balance. While there are no specific probiotics for stress and anxiety, supporting gastrointestinal health with a daily, clinically studied probiotic is a science-informed wellness practice. Speak with a healthcare professional if you are managing a diagnosed mental health condition.

Most people notice changes in digestive comfort within one to two weeks of a daily probiotic capsule routine. Effects on overall gut microbiome balance and general well-being typically take longer, four to eight weeks, which is a reasonable timeframe to assess. Because everyone's microbiome is unique, the probiotic timeline vary based on gut health, diet, and lifestyle. For best results, take your Bio-K+ capsule at the same time each day and keep the desiccant sachet in the bottle to maintain potency until the expiration date.

Bio-K+ probiotic capsules are a safe probiotic capsule for pregnancy, containing Lacticaseibacillus casei LBC80R®, Lacticaseibacillus rhamnosus CLR2®, and Lactobacillus acidophilus CL1285® proprietary strains, among the most studied in published research. Current evidence suggests Lactobacillus strains are generally well tolerated in healthy pregnant individuals, and multiple meta-analyses have not reported an increase in adverse fetal outcomes with probiotic use during pregnancy. 

That said, all supplement use, including Bio-K+ during pregnancy, should be discussed with your healthcare provider before beginning, as individual health circumstances vary.

Published research on probiotics during pregnancy includes studies for probiotics in the first trimester and probiotics in the third trimester. There is no universally agreed-upon best trimester to begin probiotic supplementation, and individual factors matter. Speak with your midwife, obstetrician, or family doctor about the timing that makes sense for your health profile and stage of pregnancy. Bio-K+ capsules are shelf-stable and easy to incorporate into a daily routine at any stage.

No. Bio-K+ capsule refrigeration is not needed. All Bio-K+ probiotic capsules, including Women's Health, Daily Care, Daily Care+, and On-the-Go formats, are shelf-stable and require no refrigeration. Each bottle contains a desiccant sachet that maintains dryness and stability, ensuring CFU potency is guaranteed until the expiration date. For the best Probiotic capsule storage, keep the desiccant sachet in the bottle at all times. Store in a cool, dry place away from direct heat and humidity.

Choosing the right probiotic capsule potency can be tricky. For gastrointestinal support, a graduated approach is recommended: start with Daily Care (12.5B CFU), progress to Daily Care+ (25B CFU), and maximize with On-the-Go (30B CFU) as needed. 

If you are choosing the Women's Health Probiotic Capsules for vaginal and vaginal health and need to know the CFU count in women's probiotic capsules, the formula contains 2B CFU of GR-1™ and RC-14™, which are distinct strains studied specifically for women's vaginal health and are not comparable to the CFU counts in the gastrointestinal line. For guidance on which capsule is right for your specific health goals, consult a healthcare professional or a pharmacist.
