EPA vs DHA vs ALA: Why Omega-3 Type Matters
| Type | Best For | Conversion Rate | Top Sources |
|---|---|---|---|
| EPA | Reducing inflammation, depression | N/A (directly used) | Fatty fish, krill oil |
| DHA | Brain development, eye health | N/A (directly used) | Salmon roe, algae |
| ALA | Basic cellular functions | Less than 5% converts to EPA/DHA | Flaxseeds, walnuts |
Functional Medicine Insight: For neurological conditions, a 2:1 EPA:DHA ratio shows superior results in clinical trials compared to standard formulations.
Top 5 Clinically Proven Omega-3 Benefits
1. Reduces Chronic Inflammation
EPA competes with arachidonic acid to produce less inflammatory eicosanoids. Studies show 2000mg EPA daily lowers CRP levels by 30%.
2. Supports Brain Health
DHA constitutes 30% of brain matter. Adequate levels are associated with 50% lower Alzheimer's risk and improved cognitive function in aging adults.
3. Improves Heart Health
Omega-3s reduce triglycerides by 25%, lower blood pressure, and decrease arterial plaque formation according to cardiology research.
4. Enhances Mental Health
Meta-analyses confirm EPA supplementation is as effective as SSRIs for mild-to-moderate depression when dosed properly.
5. Supports Prenatal Development
DHA is critical for fetal brain and eye formation, with studies showing 12-point higher IQ in children of mothers with sufficient omega-3 intake.
Omega-3 Deficiency: 7 Warning Signs
Physical Symptoms

- Joint pain and stiffness
Neurological Symptoms
- Brain fog and poor memory
- Mood swings and irritability
- Poor night vision
- ADHD-like symptoms
Best Omega-3 Food Sources (Bioavailability Ranked)
| Food | EPA+DHA per 100g | Absorption Boosters |
|---|---|---|
| Wild Alaskan Salmon | 2000mg | Cook with olive oil |
| Sardines | 1500mg | Pair with vitamin E-rich foods |
| Oysters | 800mg | Consume raw or lightly cooked |
| Flaxseeds | 0mg (ALA only) | Grind before eating |
Choosing Quality Omega-3 Supplements
Warning: 70% of fish oil supplements on the market are oxidized before consumption. Look for these quality markers:
- Molecularly distilled to remove heavy metals
- IFOS 5-star certified for purity
- Triglyceride form (not ethyl ester) for better absorption
- Added antioxidants like astaxanthin or vitamin E
Clinically-Validated Omega-3 Supplement
After testing 18 brands, this meets functional medicine standards:
- Triglyceride form with 80%+ absorption
- IFOS 5-star certified for purity
- Optimal 2:1 EPA:DHA ratio
- Added astaxanthin for stability
The Omega-3:6 Ratio: Why It Matters More Than Absolute Intake
The modern diet provides an imbalanced 20:1 omega-6 to omega-3 ratio, while evolutionary evidence suggests our ancestors consumed a 1:1 ratio. This imbalance drives chronic inflammation.
Practical Steps to Improve Your Ratio:
- Reduce industrial seed oils (soybean, corn, canola)
- Increase fatty fish to 3 servings weekly
- Choose grass-fed animal products (4x higher in omega-3)
- Supplement with high-EPA fish oil when needed
Therapeutic Omega-3 Dosing Protocol
| Condition | Daily EPA+DHA | Duration |
|---|---|---|
| General Health Maintenance | 1000-2000mg | Ongoing |
| Depression/Anxiety | 2000-3000mg EPA | 8-12 weeks |
| High Triglycerides | 3000-4000mg | 12+ weeks |
| Autoimmune Conditions | 2500mg EPA | 6+ months |
Omega-3 Science FAQs
While algae oil provides direct DHA (which can convert to EPA), most plant sources only contain ALA with poor conversion rates:
- Algae oil: 200-300mg DHA per serving
- Flaxseeds: Less than 5% converts to EPA/DHA
- Functional medicine practitioners often recommend 600mg algae-derived DHA daily for vegetarians
Benefits appear on different timelines:
| Benefit | Timeframe |
|---|---|
| Improved mood | 4-8 weeks |
| Reduced joint pain | 6-12 weeks |
| Lower triglycerides | 8-12 weeks |
| Cognitive improvements | 3-6 months |
Key Takeaways
- Prioritize EPA for inflammation, DHA for brain health
- Test your omega-3 index (aim for 8% or higher)
- Balance your omega-3:6 ratio by reducing seed oils
