Fish Oil and Risperidone, a synergy.
Fish oil, as a source of omega-3 polyunsaturated fatty acids, has been studied as an adjunct in recent-onset psychosis patients treated with risperidone. Trials suggest possible benefits for depressive/anxiety symptoms and brain white-matter measures, while broader schizophrenia omega-3 findings remain mixed. This is an adjunctive strategy, not an antipsychotic replacement.

Synergy
What is happening. Fish oil, as a source of omega-3 polyunsaturated fatty acids, has been studied as an adjunct in recent-onset psychosis patients treated with risperidone. Trials suggest possible benefits for depressive/anxiety symptoms and brain white-matter measures, while broader schizophrenia omega-3 findings remain mixed. This is an adjunctive strategy, not an antipsychotic replacement.
Mechanism. EPA and DHA can alter neuronal membrane composition, inflammatory signaling, and oxidative-stress pathways that may complement antipsychotic treatment. Risperidone provides dopamine D2 and serotonin 5-HT2A antagonism, while omega-3 effects appear indirect and illness-stage dependent.
Recommendation. Do not reduce or stop risperidone because you start fish oil. If you add fish oil, use a consistent product and track mood, anxiety, psychosis symptoms, and adverse effects over several weeks. Use extra caution if you also take blood thinners or high-dose NSAIDs, because fish oil can add bleeding tendency in those settings.
