Although my son can eat all fish and other seafood, yet he has a major increase in his Tourette tics if he has fishoil supplements. He can take flaxseed oil with no probs

the reactivity to fishoil with increased tics has been reported by many others on Latitudes and elsewhere

I am really curious as to why tho? I could understand if there was an overall allergy to fish, but this is not the case. And no other reaction is seen to the fish oil other than a big increase in tics
