ANTI-OXIDANTS
ANTI-OXIDANTS: Anti-oxidants are a type of drug or supplement that help protect the body from free radicals, which are molecules that can cause damage to cells and contribute to various diseases, including cancer, heart disease, and aging. They work by preventing or reducing the oxidative stress caused by free radicals.
The primary use of anti-oxidants is to improve overall health and prevent or delay the development of chronic diseases associated with oxidative stress. They are also used as adjuvant therapy in some specific conditions, such as age-related macular degeneration (AMD) and certain cardiovascular diseases.
The mechanism of action of anti-oxidants involves neutralizing or reducing the harmful effects of free radicals. They do this by donating an electron to the free radical, thereby stabilizing it and reducing its potential to cause damage. Common examples of anti-oxidants include vitamins A, C, and E, selenium, beta-carotene, and other plant-derived compounds like resveratrol and quercetin.
The dose of anti-oxidants can vary depending on the specific compound being used. In general, it is advised to obtain them through a balanced diet rich in fruits, vegetables, and whole grains. However, in cases where dietary intake is insufficient, supplementation may be considered. The recommended daily doses for supplements can vary widely based on age, sex, and specific health conditions, so it is important to consult with a healthcare professional for appropriate guidance.
While anti-oxidants are generally considered safe, they can have side effects in high doses or when taken in excess. For example, excessive vitamin C intake can cause digestive issues like diarrhea and stomach cramps. High levels of vitamin E supplementation may increase the risk of bleeding in individuals on blood-thinning medications. Additionally, some studies have suggested that high-dose antioxidant supplementation may interfere with the benefits of certain cancer treatments. It is crucial to follow recommended dosages and consult with a healthcare professional before starting any new supplement regimen.
