Based on multiple meta-analyses showing EPA-dominant formulas >1g/day most effective. Effects plateau around 2-2.5g. Adjunctive use with antidepressants shows better outcomes than monotherapy.
Meta-analysis (Brown 1999) found a roughly linear -0.045 mmol/L total-cholesterol drop per gram of soluble fiber within a 2-10 g/d range; the effect is small and plateaus, and GI tolerance limits higher intakes. Effect is weaker in people with normal baseline cholesterol.
