waitingforgodot, i also used fish oil for my hyperactive daughter. I read quite a lot about it, but the improvements were not easy to notice. Still she did manage to focus more over the time, was it just the growing up? (she had it for more than a year and a half) or was it the fish oil? I couldn't really tell the difference, but she is behaving better. Fish oil comes in many different varieties. Look at the content of EPA/DHA, those are basically the most important omega 3 fatty acids. Not all brands have the same concentration of those two. Also:
this is from wikipedia: "Some urge caution when taking cod liver oil and other fish-based supplements since they may contain elevated levels of toxins such as mercury and PCBs found in fish.[21] Some supplement companies regularly test cod liver oil for purity, while others do not. Consumerlab.com tested 44 fish and cod liver oil supplements and found that all were free of detectable levels of mercury."
there are many researches like this one on the www:
"Researchers are trying to find out if fish oil supplements, namely omega-3, will help special children who suffer from behavioral and learning difficulties.// The omega-3 contains a fatty acid EPA which serves to help the brain to transmit messages between the different cells. It has already been proved that it can contribute towards improving concentration, memory, mood, and behavior."
While i read many of these, we had a month ago a psychologue telling us that the fish oil will only help my daughter's skin get prettier, while a week later our ped recommended us extra omega 3 for DD.
I'm confused, but not so confused as to forget to buy a new bottle of fish oil today
