Abstract
This study aims to study the antioxidant effect of functional supplements based on cereal kernels (triticum aestivum) on the body. Cereal kernels contain natural polyphenol compounds, flavonoids and vitamins, which protect cells from oxidative stress by reducing the formation of free radicals. In the study, cereal kernel supplements at different doses were tested in laboratory conditions, and indicators such as lipid peroxidation, superoxide dismutase and glutathione peroxidase activity were analyzed in an animal model. The results showed that functional supplements based on cereal grains significantly increase antioxidant defenses and enhance the body's ability to fight free radicals. These findings may serve as a basis for the development of natural antioxidant sources in the food and pharmaceutical industries.
