Evidence by Outcome

Cardiovascular (high-risk)

Strong Evidence

25% CVD risk reduction at 4g EPA/day (REDUCE-IT)

20 studies50,000 participants

Triglycerides

Strong Evidence

15-30% reduction at 2-4g/day

40 studies15,000 participants

Depression

Moderate Evidence

SMD -0.61 for EPA-predominant (Translational Psychiatry 2019)

26 studies2,160 participants

Cognitive Decline Prevention

Insufficient Evidence

No clear benefit in healthy adults (Cochrane 2022)

12 studies25,000 participants

Heart Attack Prevention

Moderate Evidence

28% reduction (VITAL)

5 studies25,000 participants

Dosing Guide

Standard Dose

1-2g combined EPA+DHA/day

Timing

With meals containing fat

Take with food

Triglyceride form absorbs 50% better than ethyl ester. EPA-predominant for mood, DHA for development.

Known Interactions

🟢synergy+ Vitamin D3

Both fat-soluble, both support immune function. Take together with a fatty meal.

Source: Practical co-administration

Omega-3 reduces inflammation; CoQ10 supports mitochondrial energy. Both cardiovascular protective. Take together with fat.

Source: Mechanistic reasoning + both fat-soluble

🟢synergy+ Vitamin D3

Omega-3 may enhance vitamin D receptor expression. Both support immune function. Take together with fat.

Omega-3 anti-inflammatory + ashwagandha adaptogenic. No known negative interaction. Complementary for stress management.

Source: No interaction data; mechanistically complementary

Both cardiovascular protective. K2 prevents calcification, omega-3 reduces inflammation. No negative interaction.
