Table 1

Cut-off Values for the Fatty Acid Ratios which place the Levels of Total Omega-3 Fatty Acids, DHA, and EPA+DHA in the 'Lower Risk' Categories with 95% Confidence Level

Cut-offs for Fatty Acid Ratios

Fatty Acid Levels * (Lower Risk Category)





Total Omega-3 (≥7.2)





DHA (≥4.5)





EPA+DHA (≥4.6)





* The 'lower risk' categories for total omega-3, DHA, and EPA+DHA levels (as % of total fatty acids in serum phospholipid) are for coronary heart disease in the case of total omega-3 and DHA [3,4] and for fatal ischemic heart disease in the case of EPA+DHA [4,5].
