saw this on the mercola website. of course i think he sells krill oil. not sure what to make of this yet, but just passing it on.
"A total of 113 participants ... were randomized into three groups. Thirty-six were given 6 capsules of 3g krill oil a day, with 543 mg of EHA and DHA; 40 were given 3 capsules of 1.8g fish oil a day, with 864 mg of EPA and DHA ... The remaining 37 received no supplementation ... [T]here was a significant increase in plasma EPA, DHA, and DPA in both the krill oil and fish oil groups ... and no significant differences were seen between the fish oil and the krill oil groups. The EPA + DHA dose in the krill was 62.8 % of that in the fish oil."
