Best Antioxidants: Benefits, Natural Sources & Supplements
Antioxidants help protect your body’s cells from damage caused by free radicals—unstable molecules produced during normal metabolism, pollution, smoking, UV rays, stress, poor diet, and inflammation. While your body naturally produces some antioxidants, consuming antioxidant-rich foods provides additional protection and supports overall health.
What Do Antioxidants Do?
Antioxidants neutralize free radicals before they can damage healthy cells. Long-term oxidative stress has been linked to aging and several chronic diseases.
- Protect cells from oxidative damage
- Support heart health
- Help maintain healthy brain function
- Support healthy skin and collagen production
- Protect eye health
- Support immune function
- Reduce oxidative stress caused by pollution and UV exposure
- Support healthy aging
- Help recovery after normal exercise
