Why was this study done?
To observe the correlation between red blood cell (RBC) Omega-3-Index (O3I) level and Omega-3 fatty acids (EPA+DHA) intake from the supplemental fish oil in adults because O3I is proposed as a marker for coronary heart disease (CHD), suggesting that O3I below 4% as a higher risk while 8+% as a lower risk.
What did the study find?
Men and women who supplemented with fish oil containing omega-3-fatty acids (average 1.36 g/day of EPA+DHA) showed O3I level higher than 8.5%, suggesting that supplementing with omega-3 fatty acids from fish oil may lower the risk of coronary heart disease.
