Probiotics: Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. These are typically found in fermented foods like yogurt, kefir, sauerkraut, and kimchi. Probiotics contain beneficial bacteria strains such as Lactobacillus and Bifidobacterium.
Paraprobiotics: Paraprobiotics, on the other hand, are non-viable microbial cells or cell fractions of probiotics. These non-viable microbial components, such as cell walls, metabolites, and other cell components, are believed to confer health benefits even though they are not live microorganisms. Paraprobiotics are gaining attention for their potential health benefits, particularly for people who may not want or be able to consume live probiotics.
