| (All reported fatty acids) | % weight |
|
||
| Docasahexaenoic Acid C22:6n-3 | % weight |
|
||
|
DHA (Docosahexaenoic Acid) scores of >4.50 are associated with low risk of CHD.
|
||||
| Total Omega-3 Fatty Acids | % weight |
|
||
|
Total Omega-3 scores of > 7.20 are associated with low risk of CHD
|
||||

||
|
Interpretive guidelines for Omega-6 scores have not been established.
|
||||
| EPA + DHA (20:5n3+22:6n3) | % weight |
|
||
|
EPA (Eicosapentaenoic Acid) plus DHA scores of > 4.60 are associated with low risk of fatal heart disease.
|
||||
| OM3/OM6 Ratio |
|
|||
|
An Omega-3/Omega-6 score of 1:3 is consistent with anti-inflammation.
|
||||
| AA/EPA Ratio |
|
|||
|
