Scientists believe that probiotics are live microorganisms that grant health benefits to the host when administered in adequate amounts. The administration of probiotics has been majorly linked with benefits in the gut and immune system, among other health benefits. However, the health benefits of probiotics are both strain and dose-dependent on probiotic function. Compared to sedentary people, an athlete's gut microbiota composition has been linked to the level of activity, the volume of exercise, and the volume of protein consumption. Specific probiotic strains can increase the absorption of key nutrients in athletes, affecting the properties of crucial food components. Probiotic supplementation has been shown to promote healthy responses to immune depression in athletes. This immune depression can occur with excessive training load, psychological stress, lack of sleep, and environmental extremes. Athletes training in prolonged exercise in the heat has been shown to increase gut permeability, potentially resulting in systemic toxemia, which is when the body's defense mechanisms activate to fight off toxins or bacteria that can cause injury to tissue in the body. Specific probiotic strains can help to improve the integrity of this gut barrier and help reduce the risk of systemic toxemia. Improved recovery from muscle-damaging exercise has been linked to administering specific anti-inflammatory probiotic strains. Products that contain probiotics must include the minimal effective dose and method of administration as well as the genus, species, and strain of every live microorganism on the product's label. Lastly, probiotics benefit athletes through improved body composition, lean body mass, average age-related declines in testosterone levels, reduced cortisol levels, reduced levels of exercise-induced lactate, and increased neurotransmitter synthesis, cognition, and mood levels. Probiotics, if administered appropriately, can significantly benefit athletes and help optimize overall health, performance, and recovery.
