Throughout your life, your skeleton is in a continuous state of renewal. Old, worn bone tissue is removed by osteoclasts and replaced by fresh matrix laid down by osteoblasts. In childhood and early adulthood, formation outpaces resorption — bone mass accumulates until it reaches its peak, typically in the late twenties.
After peak bone mass is reached, the balance gradually shifts. By the mid-thirties, resorption begins to gain the upper hand — a change that accelerates dramatically for women after menopause, when the protective effect of oestrogen on bone formation is lost. For men, the shift is slower but cumulative, typically becoming clinically significant from the late forties.
The consequence is a progressive reduction in bone density and trabecular microarchitecture — changes that are invisible, painless, and measurable only with specialist imaging such as DXA. Osteoporosis is the clinical threshold at which this loss has advanced far enough to substantially increase fracture risk.
What this biology also means, however, is that the process is not simply passive decline. Osteoblasts are always working. The right pharmacological treatment, nutritional support, and mechanical stimulus through weight-bearing exercise can shift the balance back toward net formation. This is the scientific basis for the 8–12% annual bone density improvements achieved in the LOC BoneRevive® Programme.

What Is Happening in Bone |
Clinical Relevance |
| Childhood & adolescence |
Bone formation significantly exceeds resorption. Bone mass accumulates rapidly — up to 90% of peak bone mass is reached by age 18. |
Maximising peak bone mass through nutrition and physical activity has lifelong consequences for fracture risk. |
| 20s–30s |
Bone remodelling continues in balance. Most people reach their peak bone mass between the ages of 25 and 30. |
Peak bone mass is the strongest predictor of bone health in later life. What you do now matters more than most people realise. |
| 40s–50s |
Bone formation and resorption begin to diverge. Loss is gradual until menopause, then accelerates sharply in women due to oestrogen decline. |
The decade before and after menopause is the highest-risk period for rapid bone loss. Early assessment can identify loss before it becomes clinically significant. |
| 60s and beyond |
Bone loss slows in rate but is now cumulative. Fracture risk rises substantially, particularly at the hip, spine, and wrist. |
This is when fragility fractures occur — but the clinical opportunity for improvement is not lost. Anabolic-first intervention can still achieve meaningful BMD gains. |
