Every second, millions of red blood cells (RBCs) circulate through our bodies, constantly exposed to high oxygen tension that threatens their integrity. To counter this threat, specialized defense mechanisms protect these crucial cells, including what are the three antioxidants that stabilize the RBC membrane.

According to the National Institutes of Health, an imbalance between free radicals and antioxidants in the body is known as oxidative stress, which can damage cells. This complex process is combated by a sophisticated system of defense mechanisms, revealing what protects cells against oxidative damage.

According to scientific research, an imbalance between free radicals and antioxidants, known as oxidative stress, prepares the ground for numerous chronic and degenerative disorders. Antioxidants are critical compounds that safeguard cells from this damage, acting as a crucial defense mechanism against cellular injury.

According to a 2015 study published in *Nature*, excessive levels of antioxidants can promote the spread of melanoma cells in mice, challenging the long-held belief that more antioxidants are always better. This discovery, along with other research, has led to a critical re-evaluation of whether taking too much antioxidants is actually bad for you.

The human body maintains a delicate balance between free radicals and antioxidants; disrupting this equilibrium can lead to a condition known as "reductive stress" or the **can too much antioxidants cause oxidative stress** paradox, challenging the belief that more is always better.

Recent research reveals that vitamin D deficiency is a major global public health problem. Beyond its well-known function in bone health, evidence is increasingly showing that **is vitamin D an antioxidant nutrient** in an indirect yet significant way by regulating cellular defense systems and mitigating oxidative damage.

Over 90% of a healthy cell's total glutathione exists in its active, reduced form (GSH), ready to neutralize harmful free radicals. Understanding what happens when glutathione is reduced is crucial to grasping its profound role in protecting cells, and conversely, why its depletion is a major threat to overall health.
