Probiotics are live microorganisms that, when consumed in adequate amounts, confer health benefits, especially in terms of gut health. Common probiotic strains include various species of Lactobacillus, Bifidobacterium, and Saccharomyces.
In sports nutrition, probiotics may support digestion, nutrient absorption, immune function, and even mood regulation—factors that indirectly influence training performance and recovery. A balanced gut microbiota also contributes to reduced inflammation and better metabolic health.
They are commonly found in fermented foods and as capsule or powder supplements.
