Which vitamin plays a key role in helping blood clot properly?

Vitamin K is essential for producing several proteins involved in blood clotting, and a deficiency can lead to excessive bleeding or bruising. It is found in leafy green vegetables like spinach and kale, and small amounts are also produced by bacteria in the gut. Newborns are often given a vitamin K injection at birth since their gut bacteria have not yet developed enough to produce it. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
