Osteoporosis & Bone Health

Osteoporosis is often seen as a calcium deficiency disease, but that is far too simplistic. Bone is living tissue, constantly being broken down and rebuilt. If the removal of old bone exceeds the laying down of new bone, bone loss occurs. The question is not only how much calcium is consumed, but what governs the cells controlling this process.

Two cells are central: osteoclasts remove old bone, while osteoblasts build new bone. Oestrogen slows osteoclast activity, but progesterone stimulates osteoblasts, helping form new bone. This is why progesterone is so vital. Without sufficient progesterone, bone formation can falter, no matter how much calcium is taken.

Many factors contribute to osteoporosis: declining progesterone with age, excess oestrogen, anovulatory cycles, stress, lack of exercise, smoking, excess alcohol, corticosteroids, inflammatory processes, poor digestion, and nutrient deficiencies. Among these, vitamin D deficiency is one of the most overlooked. Without vitamin D, calcium absorption is impaired, bone mineralisation suffers, and fracture risk rises. Magnesium and vitamin K2 are also critical cofactors often ignored.

Inflammation and oxidative stress can further accelerate bone loss. So can excess sugar, insulin resistance, and the endocrine disruptors now so common in modern life. These all tend to disturb the delicate hormonal balance on which healthy bones depend.

Osteoporosis does not appear overnight. It develops over years, often silently. Prevention is far easier than reversal. Supporting progesterone levels, ensuring adequate vitamin D, correcting nutrient deficiencies, reducing inflammation and maintaining weight-bearing activity all help protect bone.

Strong bones are not built by calcium alone. They depend on a harmonious interplay of hormones, nutrients and cellular activity. Restore that balance, and you support the body’s own remarkable ability to maintain and rebuild bone.
