Free radicals are compounds that can cause damage if their levels in the body get too high. These are formed naturally when you exercise and when your body converts food into energy. Additionally, the body is exposed to free radicals from sources such as environmental pollution, sunlight, and cigarette smoke. Scientific studies have linked the effect of free radicals on the body to multiple diseases, including diabetes, coronary heart disease. As well as with aging.
Antioxidants are molecules that fight the effect of free radicals in your body. These can be found especially in foods such as fruits and vegetables. Some of the best antioxidants are beta-carotene, vitamin C, vitamin E, and selenium. If your diet doesn’t contain enough fruits and vegetables, or is deficient in some nutrients, it may be beneficial to supplement with a nutritional supplement that contains antioxidants.
