High Omega-3 Index Associated With Cellular Health Benefits
The omega-3 index is a measure of the amount of EPA and DHA in the blood, specifically the red blood cell membranes. An omega-3 index of 8% or higher is considered optimal. A new study has found that a higher omega-3 index may provide red blood cell health benefits.
The study included 25,485 participants. Blood samples were used to evaluate the omega-3 index and red blood cell distribution width. Red blood distribution width measures how equal red blood cells are in size.
The researchers found that participants with a higher omega-3 index had lower red cell distribution width. High red blood cell distribution width can be an indicator of an underlying condition such as anemia, inflammation, or heart disease.
The study was conducted by researchers from Tufts University and the Fatty Acid Research Institute. It was published online ahead of print on November 22, 2021 in the journal Prostaglandins, Leukotrienes and Essential Fatty Acids.A previous study found that a higher omega-3 index may be associated with lower systemic inflammation
