Spore Probiotics and Regular Probiotics are both live beneficial bacteria taken to support gut health, but they come from completely different bacterial families and behave very differently once you swallow them.
Regular probiotics are built around lactic acid bacteria, mostly strains from the Lactobacillus and Bifidobacterium families. These are the strains found in yogurt, kefir, and the majority of probiotic supplements sold in pharmacies.
They are active, living organisms at the time of consumption. Their survival through the digestive tract depends on the product’s formulation, the dose, and what you eat alongside them.
