Antioxidants
(53 Results)
Antioxidant supplements help protect against harmful free radicals that can destroy healthy cells and promote the cell aging process. Even intense exercise can increase the production of free radicals, which can damage muscle cells, making antioxidants important for athletes and fitness enthusiasts. Many ingredients act as antioxidants in the body, including Vitamins C and E, selenium, beta-carotene, lutein, resveratrol, grape seed, coenzyme Q10 (known as CoQ-10), and many more. An antioxidant supplement usually contains one or a combination of these powerful ingredients. GNC offers many different types of antioxidant supplements, ingredients, and dosages to choose from.
