Omega-3 2025: Fish oil vs. algae oil – effects, price & buying advice
What distinguishes good Omega-3 products, which dosages are sensible and how popular brands fare in a price/performance comparison – clear, well-founded, transparent.
Why Omega-3 counts
The long-chain fatty acids EPA and DHA make a proven contribution according to EU regulations: EPA and DHA contribute to normal heart function (from 250 mg/day); DHA contributes to the maintenance of normal brain function and vision (250 mg/day each).* Source: see EFSA/EU Register .
- Daily intake: 250–500 mg EPA+DHA/day is considered a sensible range for adults.
- Source: Fish oil (often richer in EPA) vs. algae oil (vegan, often richer in DHA) – both are effective.
- Form: Triglyceride (TG) and re-esterified (rTG/EE) effectively deliver EPA/DHA; freshness and transparency are crucial.
* Approved health claims according to Regulation (EU) 432/2012; conditions apply.
