 This study suggests that supplementing Dekosahexionic acid, DHA, a type of omega-3 fatty acid, may help reduce oxidative stress caused by prolonged exercise in physically active individuals. The researchers found that DHA supplementation had a dose-dependent effect on reducing oxidative stress markers in the body. They also observed that DHA supplementation increased the amount of DHA and other omega-3 fatty acids in the bloodstream, while leaving other types of fats such as icosapentinoic acid, EPA, and polyunsaturated fatty acids, PUFA, unchanged. This suggests that DHA may have a protective effect against oxidative stress caused by exercise. This article was authored by Lydia de Salazar, Carlos Contreras, Antonio Torregrosa-Garcia, and others.
