How does Smart Basics Calcium 600 mg + Vitamin D work?
Calcium is an essential mineral found in the body. It is the most abundant mineral in bone, necessary for its structure, its strength and its ability to maintain healthy bone mass. It helps build and maintain strong teeth and is also stored in nerves, muscles and tissues. Because calcium is used in almost every function, the body needs it more than almost any other mineral. Calcium also promotes a healthy immune system, sound nerve conduction and muscle contraction. 
 
Vitamin D promotes the absorption of calcium and helps maintain healthy phosphorous levels in the body. It works with a number of other vitamins, minerals and hormones to promote bone mineralization. Cholecalciferol, also known as vitamin D3, is the most active form of calcium. It is manufactured by the body when the skin is exposed to the UV rays of the sun. It may be necessary to supplement this vitamin within the diet due to inclement weather, aging, excessive use of alcohol, strict vegetarian (vegan) diets and overactive parathyroid glands.
