Vitamin K is essential for proper blood clotting and plays a supporting role in bone metabolism. Rabbits obtain vitamin K from two sources: dark leafy greens (which are rich in vitamin K1) and bacterial synthesis in the cecum (vitamin K2, absorbed through cecotropes). Between these two sources, vitamin K deficiency is very rare in rabbits eating a normal diet.
A few leaves of kale (about 30g) provide a generous 130mcg of vitamin K1 — your rabbit needs only about 1 to 2mg of vitamin K per kilogram of diet, abundantly supplied by any diet that includes dark leafy greens and normal cecotrope consumption.
0.0% of daily nutrient intake
Vitamin K makes up 0.0% of your domestic rabbit's total daily nutritional requirements by weight. That's a tiny amount — but it matters.
Excessive or prolonged bleeding from minor wounds, bruising, and in severe cases, internal hemorrhaging. This is extremely rare in rabbits on a normal diet.
Vitamin K from food sources does not accumulate to toxic levels. Excess is not a practical concern.
