Calcium is likely one of the first nutrients ever consumed by an individual. From the time you were born, calcium was likely introduced for its benefits of bone growth, muscle and nerve function, as well as heart function. As we age, the importance of calcium is also important as the need shifts from growth to maintenance of optimal function. If optimal calcium levels are not met, whether it be in childhood or adulthood the risk of deficiency can lead to less than optimal function and quality of life later on.
