Probiotics are the ‘good bacteria’ in our bodies that help keep us healthy. While mostly known as good gut bugs, there are also beneficial bacteria in our mouth, on our skin, in the vagina and other locations as well. The good bacteria or probiotics, if taken as a supplement, help with digestion, immune function, hormone health and many other functions vital for health. Prebiotics are the food that probiotics ‘eat’. By incorporating fibers that we cannot digest but our gut bugs can, we encourage them to be strong and healthy themselves. This improves their population and encourages a large, healthy diversity of different bugs in our system. Fibers like inulin, chicory, acacia and others get fermented in the colon by our good bacteria help to improve digestion, immune function, regulate blood sugar and support many other benefits to us and our happy gut bugs.

CFU stands for "colony-forming unit," a measure of live, active microorganisms (like bacteria and yeast) present in a probiotic product. For example, you may see 1 billion CFU (1 × 10⁹) or 10 billion CFU (1 × 10¹⁰) on product labels. These microorganisms are intended to reach and colonize the gut, where they can offer health benefits.Each CFU represents a live microbe that can reproduce and form colonies within the digestive system, which is essential for probiotics to work effectively. The CFU count, or "dose," shows the strength of the probiotic, but it’s important to choose the right amount based on the specific health benefits desired. Research indicates that higher CFU counts may offer more advantages for certain strains and purposes. However, more isn’t always better; different health goals require different CFU levels.Selecting a probiotic involves more than just looking at CFU numbers. Factors such as strain quality, delivery method, and stability during storage all contribute to a probiotic’s effectiveness. Consulting a healthcare professional can help you choose a CFU count and formulation that align with your health goals, maximizing the benefits of probiotic use.
