Total Omega-3 Fatty Acids
The summed percentage of all omega-3 fatty acids on the panel (typically ALA, EPA, DPA, and DHA) as a fraction of total fatty acids. It is a broad measure of overall omega-3 status, related to but not identical to the Omega-3 Index.
PED Notes
Omega-3 Total is the panel's overall omega-3 sum. It is closely related to the Omega-3 Index but not the same thing: the Omega-3 Index counts specifically red-cell EPA+DHA (some panels EPA+DPA+DHA), whereas the total may also include the plant omega-3 ALA, which is far less biologically active. So a respectable Omega-3 Total driven by ALA can still coexist with a low, suboptimal Omega-3 Index. For cardiovascular purposes the marine EPA/DHA content is what matters, and a red-cell EPA+DHA of about 8% or higher is the cardioprotective target. For AAS users, improving marine omega-3 status is a legitimate, low-cost cardiovascular support measure. Values are matrix and method dependent.
When low
When Omega-3 Total is low:
- Check whether the shortfall is in the marine omega-3s (EPA/DHA/DPA) specifically, since those carry the cardiovascular benefit. A total propped up by ALA is not equivalent.
- Fish oil (EPA/DHA) -- 2-3g combined per day with food, or algal oil for non-fish eaters
- Oily fish -- 2-3 servings/week
- Aim to move red-cell EPA+DHA toward the 8%+ target; recheck after 8-12 weeks.
