They can damage cells, proteins, and DNA, leading to oxidative stress and various health issues.How are they formed? Free radicals can be formed in the body during normal metabolic processes or as a result of exposure to environmental factors like pollution, cigarette smoke, and UV radiation.The role of antioxidants: Antioxidants are compounds that neutralize free radicals by donating an electron, thus stabilizing them.
