Why calcium matters more for women in midlife
Many women reach midlife thinking about bone health for the first time.
During the years leading up to and after menopause, bone density can begin to decline more rapidly. This happens largely because falling oestrogen levels accelerate the rate at which bone is broken down.
Over time, this can increase the risk of osteopenia, osteoporosis and fractures later in life.
The good news is that nutrition plays an important role in supporting bone health — and calcium is one of the key nutrients involved.
Why bone health changes after menopause
Bone is living tissue that is constantly being broken down and rebuilt.
During younger years, bone formation generally keeps pace with bone breakdown. But after menopause, bone breakdown tends to occur faster than bone formation.
This means women can lose bone density more quickly during this stage of life.
According to guidance from Osteoporosis Australia (now known as Healthy Bones Australia), women over 50 require around 1,300 mg of calcium per day to support bone health.
However, many women do not consistently reach this level through diet alone.
Why calcium is important
Calcium plays several important roles in the body.
It helps:
• maintain bone structure and strength
• support normal muscle contraction
• support nerve function
• regulate blood clotting
Because these processes are essential for survival, the body works hard to maintain stable calcium levels in the blood.
If dietary calcium intake is too low, calcium may be drawn from bones to maintain those levels.
Over time, inadequate intake can contribute to reduced bone density.

Dairy foods remain one of the most concentrated and easily absorbed sources of calcium.
Examples include:
• milk
• yoghurt
• cheese
Other sources include:
• calcium-set tofu
• canned salmon or sardines with bones
• almonds
• tahini
• leafy green vegetables such as kale and bok choy
• calcium-fortified plant milks
Including a variety of these foods throughout the day can help women reach their calcium needs.
What about supplements?
For women who struggle to reach recommended calcium intake through food alone, supplements may sometimes be considered.
However, it is generally preferable to obtain nutrients through food where possible, as whole foods provide additional nutrients that support bone health, such as protein, magnesium and vitamin K.
Anyone considering supplements should discuss this with a healthcare professional.
Calcium is only part of the picture
While calcium is important, bone health is influenced by several factors.
These include:
• adequate protein intake
• vitamin D status
• resistance training and weight-bearing exercise
• overall energy intake
• avoiding smoking and excessive alcohol intake
Supporting bone health in midlife is about a combination of nutrition and lifestyle strategies.
The opportunity in midlife
Midlife represents an important opportunity to support bone health before significant bone loss occurs.
Small, consistent changes in nutrition and lifestyle can help protect bone density and support strength and mobility in later life.
For many women, this begins with understanding how everyday eating patterns support nutrients such as calcium, protein and vitamin D.
