Nutrient Interactions

How do other nutrients interact with vitamin D?

Vitamin D plays a role in maintaining normal blood levels of calcium. As a result, vitamin D impacts the absorption and storage of calcium. Vitamin D also stimulates the absorption of phosphorus.

Vitamin D helps to regulate the production of certain calcium-binding proteins that function in the bones and kidneys. Because these binding proteins are also dependent on vitamin K, interrelationships between vitamin D and vitamin K have become the subject of active research investigation.
