Glutathione is hailed as the master antioxidant, playing a crucial role in combating oxidative stress by donating electrons to free radicals. These unstable molecules can cause significant damage to vital cellular structures, but glutathione, produced naturally by the body, effectively neutralizes them. Unlike many dietary antioxidants with low bioavailability, glutathione's effectiveness stems from its endogenous nature, making it an essential component for overall health.
