Answer:

False

Explanation:

Vitamin K is essential for the body. It helps in blood clotting, contributes to bone health and can be used in premature babies. However, it is not essential for the absorption of vitamin B12 from the intestine. In the human body, the absorption of Vitamin B12 already starts in the mouth by saliva and continues until the end of the small intestine. In this process, several proteins are required for B12 uptake. Initially, R proteins secreted in saliva and gastric juice unite with it and accompany it to the duodenum, where pancreatic juice proteases break their bonds and allow their absorption.
