Based on multiple meta-analyses showing adjuvant benefits for diabetic conditions. Effects appear time-dependent (>12 weeks). Studies primarily used combination therapy rather than astragalus alone.
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.
