The benefits of Omega 3 health supplements are obtained if the fatty acids are not oxidized, and this is prevented by the careful processing and exclusion of air from the capsule shell. However, only the Omega 3 absorbed and enter the bloodstream, there is a risk of very active oxidized 'free radicals', turning them from good unsaturated fats in unhealthy saturated fats. 
The body naturally prevents the oxidation of nutrients producing antioxidants that neutralize free radicals. Many useful antioxidants are nutrients that we get from the food, and increasingly the effectiveness of each antioxidant measured in units of Radical Absorption Capacity of Oxygen (Oxygen Radical Absorbance Capacity = ORAC). Interestingly, the fact that some substances of herbs is much more effective than the antioxidant vitamins C and E. 
The OracOmega combines a satisfactory level of these plant antioxidants (obtained from extracts of green tea, rosemary and oregano) with fish oil, to create a very powerful product. A daily dose of two capsules provides an impressive 2,500 ORAC units combined with 760mg omega 3 fatty acids, including 390mg EPA and 260mg DHA.
