Biosyntrx, Lexington, SC, has introduced ZoOmega-3, a concentrated omega 3 dietary supplement from cold water fish. Cold water fish contain essential fatty acids suggested to play an important role in eye and body health and disease prevention. Each capsule contains 300 mg of ethyl EPA omega 3 fatty acids, which inhibit the downstream metabolism of omega 6 fatty acids, preventing excessive production of pro-inflammatory prosta­glandins. Each capsule also includes 200 mg of ethyl DHA, another omega 3 fatty acid suggested to increase cellular permeability. ZoOmega-3 is a cholesterol- and triglyceride-free supplement and contains no discernible amount of mercury or PCBs.
