Omega-3 fatty acids are considered essential for optimal health but the body does not produce them on its own. High concentrations of omega-3 is found in tuna or mackerel, but fish is not typically included in most daily diets, lowering the chances of the body receiving the recommended doses. Orthomega 820 contains fish oil from the cold, fresh waters of the Chilean coast--the least industrialized coastline in the world--providing the cleanest and most sustainable fish source. This product contains 820 mg of EPA and DHA as natural triglycerides for maximum absorption. Every batch is tested for purity and freshness to ensure no fishy smell or taste.
