I have done an extensive amount of research about the various fish oils available and found Xtend-Life from New Zealand to be very forthcoming with information about their product when emailed queries. We have tried it with the three children and myself (all amine, salicylate, lactose, and everything artificial responders) and found it to be fine (although I can’t say I noticed any benefits, I certainly didn’t notice any deterioration either). It is only available directly from them, not through stores. The website is as follows: http://health.xtend-life.com/product/Omega_3_~_DHA_Esters.aspx. [we welcome feedback]
