Antioxidants are molecules that protect your body's cells from damage by neutralizing free radicals, which are unstable compounds that cause oxidative stress. If left unchecked, high levels of free radicals can contribute to chronic illnesses like heart disease, cancer, type 2 diabetes, and Alzheimer's disease. While the human body naturally produces some internal (endogenous) antioxidants, it relies heavily on external (exogenous) dietary sources—especially plant-based foods—to maintain a healthy balance.
Antioxidant Supplements: What You Need To Know

Free radicals are normal byproducts of metabolism (like digestion and exercise) but can also spike from environmental toxins like air pollution, cigarette smoke, and UV sunlight. Because free radicals lack a full set of electrons, they aggressively steal them from healthy cellular components like DNA and proteins.Antioxidants act as "cell bodyguards" or reducing agents. They safely donate an electron to the free radical, effectively turning off its destructive chain reaction before any structural cellular damage occurs.
Antioxidant Agent

Cardiovascular Support: Prevents LDL ("bad") cholesterol from oxidizing and sticking to your artery walls, reducing the risk of heart disease.

Cognitive Health: Shields delicate brain cells from age-related oxidative damage, potentially lowering the risk of memory loss and dementia.

Skin Care: Neutralizes free radicals triggered by UV radiation and environmental pollution, minimizing visible signs of aging and calming inflammation.

Vision Protection: Slows down the progression of age-related macular degeneration and cataracts
