Which vitamin is especially abundant in kale?

Kale is especially abundant in vitamin K.

A 100-gram serving of raw kale provides about 3.7 times the Daily Value of vitamin K, making it one of the vegetable’s standout nutrients. Vitamin K helps the body form proteins involved in blood clotting and supports normal bone metabolism.

Kale is also a rich source of vitamins A and C, so those answers may seem plausible. Vitamin A supports vision and immune function, while vitamin C is important for collagen formation and antioxidant protection. However, vitamin K is the clearest answer when asking which vitamin is especially abundant.

Kale belongs to the cabbage species Brassica oleracea. It was cultivated in the eastern Mediterranean and Anatolia by at least 2000 BCE, and its leaves can become sweeter after frost. Cooking reduces some nutrients, though vitamins A, C, and K remain substantial.
