Peak bone mass is reached by which option?

• A. 10-15 years
• B. 20-30 years
• C. 40-50 years
• D. 60-70 years

Answer: (B)

Peak bone mass is the maximum amount of bone mineral density a person reaches, achieved when bone formation has built up the skeleton during growth and puberty. For most people, the highest bone mass occurs in early adulthood, typically between the late teens and the early thirties. The 20s to early 30s window is when bones have finished accumulating the most density, before remodeling gradually shifts toward resorption with age. Reaching peak bone mass in this period helps provide a reserve that reduces osteoporosis risk later on. After this peak, bone mass tends to decline with aging, so the other age ranges fall outside the typical peak period.
