When should we use antioxidants?

Antioxidants are molecules that fight oxidative processes in the body caused by free radicals. The latter are solid, liquid or gaseous unstable particles. They are formed as a result of metabolic processes or enter the body from the outside, for example, with exhaust gases. Oxidation damages cells; some of them can be restored, others are destroyed forever, writes RBC.
When should we use antioxidants?

Oxidative stress from free radicals causes a variety of diseases, including cardiovascular disease, diabetes, Alzheimer's, Parkinson's, and eye problems such as cataracts and age-related macular degeneration. Antioxidants slow down these processes, and in some cases reverse them by repairing damaged cells.

The symptoms of lack of antioxidants include the following:

Dry skin;

Rapid fatigability;

Mental breakdown;

Frequent contagious diseases;

Sleep problems;

Hair loss, brittle nails;

Premature wrinkles;

Dental diseases;

Muscle weakness.

The scientists have not yet reached common ground on benefits of consuming large amounts of antioxidants in the form of supplements. Overabundance of them, at best, has no effect, at worst, is harmful. The National Institutes of Health study shows that high doses of beta-carotene are associated with an increased risk of lung cancer in smokers. Excessive consumption of antioxidants can be toxic and promote oxidative damage rather than prevent it. This phenomenon is known as the antioxidant paradox.
