Bone mass generally peaks around the age of 30-35, and then starts to slowly decline at around age 50 in women (60 in men) when you start to lose bone mass faster than your body can grow it back. This happens to all adults, however critical loss of bone mass (osteoporosis) is much more common in women.
After about 35 years of age, you begin to lose more bone that your body makes. Most people lose about 1% of bone each year after their mid-thirties. Women in their post menopausal year often experienced a much more dramatic increase in bone loss. They lose 4-5% of their bone each year for several years.
