Bio-K+ drinkable probiotic supplements are fermented in whole-food bases, pea, rice, soy, or dairy, which naturally produce prebiotic substrates as part of the fermentation process itself. This differs from products that add isolated prebiotic fiber, such as inulin or FOS, after production. The fermented base works alongside the three-strain formula to promote digestive health.† For capsule formats, Extra Care and Extra Care+ Probiotic Supplements use targeted-release technology to deliver that same three-strain formula daily.†

Probiotics are live, beneficial bacteria, like the three exclusive strains found in every Bio-K+ probiotic supplement. Prebiotic fiber is what those bacteria eat once they reach your gut. Most probiotic supplements focus only on bacterial count, leaving the feeding step to a separate product entirely. Bio-K+ fermented drinkables combine both: 50 billion live bacteria alongside natural prebiotic substrate from the fermented base, promoting digestive health† in a single daily serving, no separate prebiotic powder required at all.†

Prebiotic fiber feeds the beneficial bacteria that live naturally in your gut, helping them promote digestive health and support a balanced microbiome over time.† Food-based prebiotic sources, like those produced during fermentation of pea, rice, soy, or dairy bases, work alongside live probiotic cultures in a way isolated fiber powders simply cannot replicate. Bio-K+ probiotic supplements deliver both a prebiotic substrate and 50 billion live, active bacteria, guaranteed until the best before or expiry date, in every single serving.†

Bio-K+'s vegan drinkable probiotic supplements, fermented pea (Raspberry), fermented rice (Blueberry), and fermented soy (Mango), each deliver 50 billion live bacteria alongside a natural prebiotic substrate. Dairy-based drinkables (Original, Strawberry, Vanilla) offer the same potency in a fermented-milk format instead. For capsule options, Extra Care (50B CFU) and Extra Care+ Probiotic Supplements (80B CFU) promote digestive health† in targeted-release technology formats. The Elderberry Extra drinkable also adds Wellmune®, scientifically studied for its effects on immune function.†

Most prebiotic fiber supplements on the market use isolated soluble fibers, inulin, FOS, or acacia gum, mixed into a product after it is manufactured. Bio-K+ takes a different approach. The prebiotic substrate in its fermented, drinkable probiotic supplements is produced naturally through fermentation: the pea, rice, soy, or dairy base is transformed during fermentation, creating a food matrix that works alongside the three-strain formula from the first sip rather than arriving as a separate additive.†
