How does NSI® Calcium Citrate with Vitamin D work?Calcium citrate is a combination of calcium and citric acid (from citrus fruit) and is a highly absorbable form of calcium. ¹
Calcium is important for many aspects of health, but is crucial to the growth and maintenance of bones and teeth. Calcium is stored in the bones and teeth and works as a "bank" that the body draws from when needed. Insufficient intake of the mineral through diet can lead to depleted stores, increasing risk for developing bone-debilitating conditions such as osteoporosis.
Calcium is also necessary in assisting muscle contraction, nerve conduction, the beating of the heart, blood coagulation, glandular secretion, the production of energy and the maintenance of immune function, among other things.
Vitamin D is included in this formula, as it also increases absorption of calcium and supports bone and immune health.
NSI® Calcium Citrate with Vitamin D is better because it:
Is an easily digested and well-absorbed form of calcium.
Contains vitamin D for extra bone-health support and enhanced absorption of calcium.

Did You Know?
All NSI supplements are packaged in HDPE (High Density Polyethylene) bottles. These bottles keep moisture vapor out, protecting the freshness and integrity of their contents, and are 400% more effective compared other brands currently using PET (Polyethylene Terephthalate) bottles. HDPE bottles do not break as glass can and are also recyclable so we urge you to please recycle them.
