Omega-3 for Cortisol-Related Weight Gain
C Some Evidence Limited evidence from small studies, but some positive signals exist.Omega-3 supplementation may modulate HPA axis response to stress. Small RCTs show reduced cortisol response during mental stress tests. Anti-inflammatory effects may reduce cortisol-driven visceral fat inflammation.
