Peak bone mass
Also called: peak bone density, maximum bone mass
What it means
Peak bone mass is the maximum amount and density of bone a person builds, usually reached by early adulthood, before age-related decline begins.
A higher peak bone mass earlier in life gives you more reserve before bone loss later puts you at risk of osteopenia or osteoporosis.
Peak bone mass is the highest amount of bone you ever build, usually reached by early adulthood. During childhood and the teenage years, bones grow in size and density much faster than they break down, banking a kind of skeletal reserve for later in life. Genetics largely sets the ceiling, but nutrition and physical activity during these growing years strongly influence how close you get to it.
After peak bone mass is reached, bone density stays fairly stable for a while, then gradually declines with aging, and more rapidly for women around menopause. The higher your peak bone mass was, the more cushion you have before density drops into the osteopenia or osteoporosis range later in life — like starting retirement with a bigger savings account.
You can't go back and change your own peak bone mass now, but understanding the concept matters if you have children or grandchildren: adequate calcium, vitamin D, protein, and weight-bearing activity during childhood and adolescence help young people build stronger skeletons. For adults past this stage, the focus shifts to slowing loss and maintaining the bone you have, through activity, good nutrition, and medical care when needed.
Building more bone reserve in early adulthood protects you before age-related loss sets in.
