Probiotics are live microorganisms — primarily bacteria and yeasts — that are found naturally in fermented foods such as yogurt, kefir, kimchi, and sauerkraut. When consumed in adequate amounts, they contribute to the balance of bacteria in the digestive system. Probiotic supplements provide a concentrated, measured dose of these cultures.
What does CFU mean?
CFU stands for Colony Forming Units — it is the measurement used to count the number of viable (living) bacteria in a probiotic supplement. A supplement that states "50 billion CFU" contains 50 billion living bacterial organisms per serving at the time of manufacture. Because bacteria are living organisms, CFU counts can decrease over time, which is why storage conditions and expiry dates matter.
Why do strains matter?
Not all probiotic bacteria are the same. Different strains belong to different species, and different species have different properties. The most studied strains belong to two main genera: Lactobacillus and Bifidobacterium. A multi-strain formula covering 10 or more strains is designed to populate a wider range of niches in the digestive tract.
What is a prebiotic?
Prebiotics are non-digestible fibres that serve as food for probiotic bacteria. They are not bacteria themselves — they are the substrate that helps beneficial bacteria grow and thrive. Many probiotic supplements include a prebiotic component to support the survival and activity of the probiotic strains.
Storage and shelf life
Most modern probiotic supplements are formulated to be shelf-stable at room temperature, though some prefer refrigeration. Store in a cool, dry place away from direct sunlight. Check the expiry date — bacteria potency declines over time, particularly in warm conditions.
