Here's why you should be making sure you get enough of this essential vitamin every day: Cognitive health Vitamin D is important for maintaining cognitive health and function as you age. Healthy serum vitamin D levels have been shown to correspond with better scores on cognitive health tests and better maintenance of cognitive ability in aging individuals. Bone and immune health Vitamin D (along with vitamin K and essential minerals) is essential for facilitating the transport of calcium into the bone matrix. This is an important step in maintaining strong, healthy bones and teeth. Vitamin D also plays a critical role in healthy immune function. Heart health & blood pressure support Vitamin D helps to regulate the body's calcium balance while facilitating calcium absorption into the bloodstream, promotes a healthy inflammatory response in the cardiovascular system and encourages healthy endothelial function. Vitamin D may also help inhibit excess renin levels. Healthy renin levels help maintain healthy blood pressure already within the normal range.
