When it comes to packing in vitamin A, nothing beats beef liver. In fact, a single 3-ounce cooked serving can deliver more than 6,500 micrograms of retinol activity equivalents (RAE)—that's over 700% of your daily value! (USDA FoodData Central) This matters because vitamin A supports healthy vision, immune function, and skin integrity.
So how do other foods stack up? After beef liver, the top contenders for vitamin A per serving are cod liver oil, cooked lamb liver, and mackerel. Plant-based sources like sweet potatoes and carrots are impressive, but they contain beta-carotene, which your body converts to vitamin A at a lower efficiency than preformed sources like liver.
Here's a quick ranking by vitamin A content per serving: 1. Beef liver (3 oz, cooked): ~6,500 mcg RAE 2. Cod liver oil (1 Tbsp): ~1,350 mcg RAE 3. Lamb liver (3 oz, cooked): ~6,580 mcg RAE 4. Mackerel (1 fillet): ~388 mcg RAE 5. Sweet potato (1 medium, baked): ~1,096 mcg RAE (as beta-carotene)
Did you know? The form of vitamin A in animal products is more bioavailable than plant forms. If you want to maximize absorption, pair plant sources with a little dietary fat. But for sheer potency, beef liver is king—just keep servings modest, since too much vitamin A can be toxic over time.
If you’re feeling adventurous, try pan-searing thin slices of beef liver with onions and a squeeze of lemon. It’s an old-school superfood for a reason!
