Beta-glucans are polysaccharides found in the cell walls of organisms like oats, barley, yeast, and certain fungi, known for their immunomodulatory and digestive health benefits in horses. These molecules interact with receptors on immune cells such as macrophages and neutrophils, enhancing the horse's innate immune response. This makes beta-glucans particularly effective in improving resilience against infections and mitigating stress-related immune suppression, a common concern for performance and competition horses. In the digestive system, beta-glucans function as prebiotics, fostering the growth of beneficial gut bacteria and enhancing nutrient absorption. They bind to toxins and pathogens, protecting the gut lining and reducing the risk of conditions like gastric ulcers and colic. Additionally, their ability to stabilize blood sugar levels supports energy metabolism, making them beneficial for sustained energy during endurance activities and rigorous training schedules. Beta-glucans also play a role in reducing oxidative stress by providing antioxidant protection at the cellular level. This is particularly important for horses undergoing intense physical exertion, as oxidative stress can lead to muscle fatigue and tissue damage. Research indicates that regular supplementation with beta-glucans can improve immune resilience, promote gut integrity, and enhance overall performance, making them a valuable addition to equine diets.
