King Crab
Overview
Why eat king crab?
King crab is a lean, high-protein shellfish that delivers an unusual concentration of trace minerals for very few calories. One cooked leg brings about 130 calories with nearly 26 grams of protein, plus standout amounts of vitamin B12, zinc, copper and selenium, making it a light but genuinely nutrient-dense choice.
Good to know: Crab is naturally salty and cooked in brine, so one leg carries about 1,436 mg of sodium, roughly 62% of the daily value, which is worth watching if you're managing blood pressure.
Lean protein, few calories
A single 134 g leg supplies 25.9 g of protein (52% DV) for about 130 calories, supporting muscle repair and helping meals feel satisfying.
Remarkable B12 and minerals
King crab provides 11.5 µg of vitamin B12 per 100 g, nearly five times the daily value, which your nerves and red blood cells depend on.
Zinc, copper and selenium
Per 100 g it offers 69% DV zinc, 131% DV copper and 73% DV selenium, minerals involved in immune function, iron handling and antioxidant defense.
