Horseradish, raw

Horseradish is a root vegetable, and these figures describe the raw flesh of the root. It provides carbohydrate and protein, as well as vitamin C and potassium. Per 100g, it contains 11g of carbohydrate, 4.5g of protein, 120mg of vitamin C and 580mg of potassium.

Vitamin C supports normal immune function and helps the body form collagen, which is needed for skin and other connective tissues. It also helps the body absorb iron from plant foods. Potassium contributes to normal nerve and muscle function. These values apply to raw horseradish rather than prepared horseradish sauces, which may contain added ingredients.
