organ meats · grass-fed liver · beef liver

Some of the most nutrient-dense foods available. Liver is exceptionally high in vitamin A (retinol), B12, folate, copper, and heme iron. Traditional diets historically prioritized organ meats.

Concerns

  • Vitamin A toxicity risk with very high daily consumption — limit to 1-2 servings per week
  • Accumulates toxins if sourced from factory-farmed animals — grass-fed/pasture-raised is essential
  • High in purines — relevant to gout sufferers
