Omega-3 and DHA
DHA is a long-chain omega-3 fatty acid important for neural and visual development. The body makes limited DHA from plant ALA.
Fish to choose
Low-mercury, fully cooked options: salmon, sardines, trout, anchovies. Limit high-mercury species (shark, swordfish, large tuna).
Reference portions
Many guidelines suggest 2–3 servings of low-mercury fish per week (about 8–12 oz total) — confirm local advice.
Notes
- Fish must be thoroughly cooked.
- Algae-based DHA supplements are an option if fish intake is low — discuss dose with your clinician.
