Moderation..except there are a few key things about that study, it did not point out a cause and effect, more important the study did not look into what if any supplements the participants were taking or if any or their diets The high levels of omega 3 could be caused by a variety of reasons and not exactly from fish oil. I am not quite sure why they even stated fish oil in the headlines as of yet since its pretty inconclusive.

But yes even natural can be dangerous. Fish oil can also contain heavy metals and its pretty hard to determine what exactly is in the oil you are purchasing. Fish oil also acts as a blood thinner which can create problems for some people or problems if taken in a high dose or before surgery. The heavy metals freaks me out a bit.

"Canadian urologist Dr. Arthur Grabowski notes that the results of other studies on fish oil and prostate cancer conflict with the findings of this study.Fish oil has been found to cut the risk of dying of prostate cancer by 40 per cent, and prevent heart disease and strokes. "

I'm not sure about any supplements, our bodies don't always react the same to supplements as our bodies do to the real unaltered substance. And if you have a well planned diet there probably is not much need for extra supplements all the time for most people... I would think.

Sorry I know I am not Genetic, read that study today in the news tho and thats what I took from it anyways. Saw one on calcium supplements and females a while back too, leading to greater risk of heart attack. But then there is a gazzillion articles and studies about calcium prolonging life. What the efff ??? Very confusing indeed. And then there is always the question of who funded the studies.
