An issue of unknown consequences in the recommendation of fish oil capsules worth mentioning, is the mercury content found in many of them. Perhaps this volume of exposure is not consequential in relationship to the value of omega 3 fatty acids that are heart healthy that we can get from them. I have personally changed to flaxseed oil capsules which have the same omega 3 's without the risk of mercury. In the overall scheme of things will this change something significantly? Unknown, but enough small avoidances and changes may add up to tangible differences. I think this is one that is easy to accommodate.
