Antioxidants also appear to play a role in helping to slow your signs of aging.
Antioxidants are usually classified into two broad groups: water-soluble (hydrophilic) and lipid-soluble (hydrophobic). To fight and help neutralize damaging free radicals, you need both forms of antioxidants from as many sources as possible. When taken together, the efficacy of water- and lipid-soluble antioxidants is enhanced even more.
Examples of water-soluble antioxidants include pycnogenol, vitamin C, glutathione and astaxanthin. It exists in aqueous fluids, such as blood and intracellular and extracellular fluids. It reacts with oxidants in the cell cytosol (fluid portion of cytoplasm) and the blood plasma. Examples of water-soluble antioxidants include pycnogenol, vitamin C and glutathione.
