Recent surveys of fish oil capsules performed by independent laboratories have revealed a fairly significant proportion of rancidity in the products sampled. Researchers from Spain recently investigated just what would be the effect of consuming those oxidized fish oil capsules, and the results are not surprising. You can believe the general media and medical encouragement for more and more omega 3's, but these researchers report that when volunteers, consuming a fish-rich diet!, took the oxidized fish oil capsules, their lab tests showed a negative effect on circulating lipids.
Safe and adequate fish oil can be found in either cold water fish (salmon, halibut, herring, mackerel, sardines) consumed twice weekly or Fermented Cod Liver Oil taken on a regular basis.
