Oxidative stress

Description

Oxidative stress is an imbalance that results when a cell's waste byproducts, called free radicals, are not neutralized by antioxidant molecules.

Overview

Oxidative stress is an imbalance between levels of antioxidants and free radicals in the body. Antioxidants, such as vitamins C and E, are substances that may protect cells against damage from free radicals. Free radicals are molecules produced when the body breaks down food or is exposed to environmental triggers, such as tobacco smoke and radiation.

Symptoms

Oxidative stress can cause a range of symptoms, including muscle and joint pain, increased risk of infections, and signs of premature aging, such as wrinkles.

Treatment

Antioxidant supplements, including vitamins C and E, may help. Recent studies show the potential benefits of antioxidants like resveratrol, omega-3 fatty acids and flavonoids to help manage oxidative stress.
