Peak bone mass is reached by which age range?

Peak bone mass is reached by which age range?

• A. 5-10 years
• B. 15-20 years
• C. 20-30 years
• D. 30-40 years

Answer: (C)

Peak bone mass is the maximum bone mineral density and structural strength a person achieves, typically reached in early adulthood. Bone accumulation happens fastest during childhood and adolescence, and by the time you reach your late teens to late twenties you’ve built most of the bone you’ll have in your lifetime. Because this growth tapers off as you approach the end of the second decade and into the third, the period from about twenty to thirty years old is when peak bone mass is generally reached. After this window, bone remodeling continues, and density may slowly plateau and then decline with age. Individual timing can vary due to genetics, nutrition, hormones, and physical activity, but the twenty-to-thirty range best captures when peak bone mass is attained.
