Antioxidants are substances that can prevent or slow down the damage caused by oxidative stress. Oxidative stress occurs when there is an imbalance between the production of reactive oxygen species (also known as free radicals) and the body’s ability to neutralize or repair their damaging effects.
Free radicals are unstable molecules that can cause damage to cells, proteins, and DNA in the body. Antioxidants work by donating electrons to free radicals, neutralizing their damaging effects and preventing them from causing oxidative stress.
What are the Most Common Antioxidants?
Some common antioxidants include vitamins C and E, beta-carotene, selenium, and enzymes such as superoxide dismutase and catalase. Antioxidants can also be found in many foods, such as fruits, vegetables, nuts, and grains.
It’s important to note that while antioxidants are important for maintaining overall health and wellness, it’s also possible to have too much of a good thing. High doses of antioxidants from supplements, for example, can interfere with normal cellular processes and may even have harmful effects.
