The answer is technically no, however, Beta Glucan does help reduce free radicals in the body and can act like an antioxidant. Beta Glucan does enable the immune system to help clean up the “garbage” in a person’s body.

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.
It is, it is but in this regard we have to remember that it’s easy to measure of how well the antioxidant is in the tube, it’s easy to measure, but once I swallow it, it is almost impossible to measure any effects in our bodies. So we know that it works in tube but in our body we just expect that it’s working the same way. But it has the ability to act like antioxidant.
