In the classical sense, an Antioxidant is going to be something that either gives up an electron, grabs an electron, neutralizes a free-radical, or somehow defeats the oxidizing agent and nullifies it. Beta-1, 3D Glucan is not an antioxidant in that respect. In contrast, what you are going to find is, there is a lot of debris in the body that gives rise to free radicals.
One of the great jobs that the immune system does, the phagocytes in particular, is gobbling up and disposing of the garbage that accumulates this waste: dead and dying cells. The immune system is constantly surveying and surveilling and when it finds a cell that’s weak and dying, it’s all about disposing of that cell to eliminate the release of free radicals. In this sense, Beta Glucan has a tangible influence on the volume of Oxygen Free radicals in the body.
