A high omega-3 index has been associated with a 90% reduction in sudden cardiac death. In the United States, the omega-3 index is about 4% or lower. When I say a high omega-3 index, I mean 8% or more. A high omega-3 index has also been associated with a 5-year increase in life expectancy. So people, with an omega-3 index of 8% or more have a 5-year increase in life expectancy compared to people with an omega-3 index of 4% or lower.
