How does NSI® Calcium, Magnesium & Vitamin D work?
Calcium, magnesium and vitamin D form a powerful combination that promotes healthy teeth and bones. They also work synergistically to provide additional significant health benefits. NSI® Calcium, Magnesium & Vitamin D offers optimal amounts of these nutrients in every convenient daily serving.

Calcium is the most abundant mineral in bone, necessary for its structure, strength and ability to maintain healthy bone mass. In addition to being stored in teeth and bones, calcium is stored in the nerves, muscles and tissues. Because it is used in almost every function, the body needs calcium more than almost any other mineral. Calcium may also promote a healthy immune system. Magnesium and vitamin D increase the absorption of calcium.

Magnesium is called the “anti-stress” mineral. It promotes relaxation, supports nerve conduction and helps induce restful sleep. Magnesium also assists in the purification of body tissue and enhances energy levels.

Vitamin D is necessary for maintaining favorable calcium levels in the body. In fact, calcium is the main structural element in bones and teeth and can only be absorbed by the body when vitamin D is present. This essential vitamin also helps increase muscle strength, supports breast and colon health and promotes cellular growth. In addition, it contributes to healthy immune and nervous systems.  

NSI® Calcium, Magnesium & Vitamin D is better because it:
- Provides beneficial amounts of calcium in every convenient serving.
- Includes magnesium and vitamin D for increased calcium absorption. 
- Is physician formulated and recommended.
- Offers exceptional quality at extraordinary value.
