2. Atlantic Mackerel (1,000 to 1,500 mg per 3-Ounce Serving)

Atlantic mackerel is a rich, flavorful fish packed with robust healthy fats and essential micronutrients like vitamin B12 and selenium. Its high lipid density yields over a gram of combined EPA and DHA per serving, making it exceptional for lowering systemic vascular inflammation. Be careful to choose Atlantic or Chub mackerel rather than King mackerel; while Atlantic mackerel remains small and low in heavy metals, King mackerel accumulates significantly higher levels of environmental mercury.
