Bio-K+'s drinkable probiotic supplements are fermented in-house, delivering live and active bacteria in every bottle.

Natural probiotics come from live fermentation processes using real bacterial cultures. Synthetic probiotic blends are typically produced by freeze-drying powder strains and blending them post-manufacture. Bio-K+'s drinkable probiotic supplements contain live bacteria that actively ferment inside the bottle from production to consumption.

Bio-K+ drinkable probiotic supplements contain 50 billion live and active bacteria, guaranteed until the best before date — not at the time of manufacture. The Extra Elderberry drinkable contains 80 billion CFU. CFU count is only meaningful when potency is guaranteed to expiry, not just at the time of production.
