The good news is that you are never too old or too young to improve your bone health. At all ages, a diet with enough calcium and vitamin D, together with weight-bearing physical activity every day, can prevent problems later. The majority of bone-building occurs in children between the ages of 9 and 18. The more calcium stored in the teen years, the greater the bone mass as an adult. While calcium is important for everyone, we recommend consulting with your health care provider to determine if Adora Calcium Supplements are right for you or your children.
