Omega-3s include EPA and DHA from marine foods and ALA from plants, with different conversion efficiencies and physiological roles.
01EPA DHA ALA map
| Type | Main source | EPA+DHA per serving | Conversion and use profile |
|---|
| EPA and DHA | Salmon, sardines, trout, algae oils | Salmon 4 oz: 1.2–2.4 g. Sardines 3 oz: 0.8–1.2 g | Direct active forms for recovery and membrane integrity |
| ALA | Flax, chia, walnuts | Flax 1 tbsp: 2.4 g ALA | Only 5–10% converts to EPA, 2–5% to DHA. Useful but insufficient alone |
02Intake targets
| Goal | EPA+DHA target | Notes |
|---|
| General health | 250–500 mg daily | Achievable with two marine servings per week |
| Training and recovery | 1–2 g daily | Higher EPA ratio supports inflammation management |
| High inflammatory burden | 2–4 g daily | Requires dedicated supplementation in most cases |
03Food-first and supplement strategy
| Step | Plan |
|---|
| Primary | Two servings of marine options or algae options weekly |
| Secondary | Add plant sources for fiber and ALA spread |
| Supplement | Only when food-first coverage falls short of target demand |
04Phase checks
| Phase | Target guardrail |
|---|
| Fat-loss | Keep energy load controlled while holding source quality |
| Maintenance | Maintain regular spacing and stable totals |
| Training or recovery focus | Use high-quality sources consistently and track response |
Consider how omega-3s fit within your overall dietary fat intake, macro budget, and macro ratios before making major changes to your eating patterns. If you want a measured status check, use Omega-3 Index. If you want the full guide on what number to aim for, how much EPA and DHA usually moves it, and why ALA-rich foods do not solve the same problem, read Omega-3 Index: What Your Number Means, How Much EPA and DHA You Need, and When to Retest.
