Good news re: fish-oil supplements

They’re just as good as eating fish:

In a randomized study involving 23 healthy premenopausal female volunteers, results indicate that omega-3 fatty acids from oily fish consumed weekly or from fish-oil capsules taken daily are equally bioavailable. The subjects were randomized to consume a daily average of 485 mg eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) from 2 servings of oily fish (salmon and albacore tuna) per week (n=11) or from 1-2 fish-oil capsules/day (n=12), for a period of 16 weeks. At intervention end, EPA+DHA in red blood cells increased 2.2% in the oily fish group and 1.9% in the fish-oil capsule group. Similar results were observed for EPA+DHA in plasma phospholipids. Thus, the authors of this study conclude, “These findings suggest that the consumption of equal amounts of EPA and DHA from oily fish on a weekly basis or from fish-oil capsules on a daily basis is equally effective at enriching blood lipids with omega-3 fatty acids.”

“Comparison of the effects of fish and fish-oil capsules on the n 3 fatty acid content of blood cells and plasma phospholipids,” Harris WS, Pottala JV, et al, Am J Clin Nutr, 2007; 86(6): 1621-1625.
