All humans use antioxidants as they are in our foods and essential to life.
But unless you are eating poorly and not supplying enough for your needs, I feel you do not need to take supplements esp. when they are chemicals made my scientists which most "vitamins" are. When I take them, B's are important and also C, I take only naturally sourced, ones that come from foods. C, for example, comes from cherries and some fruit down in S. America. Filling your body with man-made chemicals that you are told are "vitamins" is not the way to go.
Having said that, some amino acids work very well, such as Taurine, which opens up small capillaries and allows blood in. My two cents.
