The study found that after one year of having stopped calcium supplementation, women continued losing bone density at pre-treatment rates. Adolescents have shown similar patterns. Calcium is especially important for adolescents, who are building bone density to peak. The trials lasted one to two years each. Again, when supplementation ceased increases in bone density slowed to levels seen in untreated children.
Calcium supplements make the task easier.
Other sources of calcium include dairy products and produce such as collards, turnip greens, rhubarb, broccoli, kale and other green-colored vegetables.
