Calamari oil (high-DHA)
Tier 3 — weak evidence · Omega-3 · DHA-rich · Sustainable
An alternative marine omega-3 oil pressed from squid (calamari) byproducts, typically providing a higher DHA-to-EPA ratio (approximately 500 DHA : 100 EPA) than standard fish oil. Useful when DHA is the priority — brain support, pregnancy, and eye health. Environmental profile is generally favourable (calamari are short-lived, fast-reproducing, and often harvested as fisheries byproduct). Lower heavy-metal load than top-predator fish oils. Still subject to oxidation — choose antioxidant-stabilised products.
Dose: 1–3 g calamari oil daily (targeting 500–1500 mg DHA)
