Most fish oil is completely ineffective:
I’ve personally noticed some powerful effects from fish oil: 1) it can act as a neotropic booster, particularly in conjunction with SRI’s and similar meds / substances, 2) it can cause me significant insomnia (no arrhythmia) if I take ~6-8 capsules.
Is that germane to this thread? Probably not, but something seems to be going on. Maybe fish oil has been studied so far on too limited a basis.
I’m not sure that’s really the opposite side, in reality.
