How do I reduce oxidative stress?

The reduction of oxidative stress could be achieved in three levels: by lowering exposure to environmental pollutants with oxidizing properties, by increasing levels of endogenous and exogenous antioxidants, or by lowering the generation of oxidative stress by stabilizing mitochondrial energy production and efficiency.

Is too much antioxidant bad?

Does vitamin C reduce free radicals?

As a water soluble molecule, vitamin C can work both inside and outside the cells, and can neutralize free radicals and prevent free radical damage. Vitamin C is an excellent source of electrons for free radicals that are seeking out an electron to regain their stability.
