Vitamin D3 Benefits

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.⁵ This is an important step in maintaining strong, healthy bones and teeth. Vitamin D also plays a critical role in healthy immune function.^5,6

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.^7,8 Vitamin D may also help inhibit excess renin levels. Healthy renin levels help maintain healthy blood pressure already within the normal range.⁹
