During exercise, as your breathing increases to meet the demands of your workout, the chemical interaction of oxygen with your cell membranes, protein and other cellular components creates unstable substances called free radicals. These highly reactive substances are much like small fires that must be extinguished before they burn, or “oxidize,” neighboring molecules in other cells, creating muscle soreness and stiffness. That’s where vitamin C steps in. As a dietary antioxidant, vitamin C blocks free radical damage in and around your cells.
Citrus fruits and dark green leafy vegetables are rich in vitamin C, along with most other fruits and vegetables (even iceberg lettuce!) However, to get enough of this powerhouse nutrient I recommend you take a vitamin C supplement every day – ideally, 1,000 milligrams.
