The only non-fish source that reliably raises long-chain omega-3 fats, matching salmon at modest daily amounts. Triglycerides fall, blood pressure falls slightly, and memory for recent events improved in older adults with age-related decline. Against this sits a consistent rise in the cholesterol that builds up in artery walls and, above about one gram daily, more irregular heart rhythm. (Full Review)
| Marker | Target | Why |
|---|---|---|
| Omega-3 Index | 8–12% of red-cell fatty acids | Confirms the oil reaches membranes |
| Triglycerides | 70–90 mg/dL | Primary metabolic target of the oil |
| LDL-C | <100 mg/dL, and no rise from personal baseline | Captures the known docosahexaenoic acid-driven increase |
| ApoB | <80 mg/dL (<60 mg/dL if cardiovascular risk is high) | Distinguishes a benign particle-size shift from more atherogenic particles |
| HDL-C | >50 mg/dL (men), >60 mg/dL (women) | Tracks the expected small rise |
| hs-CRP | <1.0 mg/L | Tracks the inflammation-resolving effect |
| HbA1c | 4.8–5.4% | Checks the disputed glycaemic effect |
| Resting pulse rhythm or single-lead ECG | No established target range; deviation from the individual's own regular baseline rhythm | Detects atrial fibrillation early |
Cadence: Baseline before starting; lipid panel with apolipoprotein B at 12 weeks and omega-3 index at 16 weeks; thereafter both every 6 to 12 months, or 12 weeks after any dose change
