Humans maintain complex systems of multiple types of antioxidants where the effect of any one antioxidant depends on its concentration, its targeted reactive oxygen species (or free radicals) and the presence of the antioxidants with which it interacts.

Antioxidants are classified into two broad divisions, depending on whether they are soluble in water (hydrophilic) or in lipids (hydrophobic). In general, water-soluble antioxidants react with oxidants in the cell cytoplasm and the blood plasma, while lipid-soluble antioxidants protect cell membranes from lipid peroxidation.

The Alpha Science antioxidant products offered through Integra Nutrition are designed to quench targeted free radicals, support antioxidant systems and sequester in different organs in both water and lipid soluble areas.
