How it works

Strong evidence supports Omega-3s for reducing triglycerides and cardiovascular risk, particularly in those with existing heart disease. It is also well-supported for mood regulation and systemic inflammation, with high-EPA formulations showing the most benefit for depression.

Incorporates into cell membranes to modulate inflammation, lowers triglyceride-rich lipoproteins, and provides structural support for neurons via DHA.

Safety

  • May have mild blood-thinning effects at high doses.
  • Increased risk of atrial fibrillation observed in some trials at doses above 1g/day.
  • Check for rancidity; oxidized oil can be pro-inflammatory.
