Good news.
In very high risk people (ages 13 to 25) 4 fish oil capsules a day for 12 weeks lowered the risk of full-blown psychosis by ~80% compared to the placebo group.
Benefits were sustained after patients stopped taking the fish oil.

So clearly...it’s not eating fish that causes psychosis...
Hey I can leap to conclusions as good as anyone else...
