Are you getting the recommended levels of calcium?

Recommended levels of calcium are highest for individuals in their teen years as this is a critical period for building bone. Aside from those critical teen years, calcium intake generally increases with a person’s age. And while many of us think that our current intake levels are adequate, more than 75% of all Americans are not getting enough calcium in their diet. In fact, 90% of women over 50 and 99% of women over 70 are not getting enough calcium from their diet.

Are you getting the recommended levels of Vitamin D?

Recommended levels of Vitamin D intake increase with a person's age. And while many of us think that our current intake levels are sufficient, over 70% of women ages 51-70 and almost 90% of women over the age of 70 are not getting enough Vitamin D.

According to the National Institute of Health, individuals at increased risk for Vitamin D deficiency are:
