Calcium and Your Bones: Building a Stronger Foundation for Life
When it comes to supporting your overall health and wellbeing, strong bones play a vital role — and calcium is one of the key nutrients that keeps them healthy. Almost 99% of the body’s calcium is stored in the bones, helping them stay dense and strong while also supporting the muscles, heart, and nervous system.
At U&A Homecare, our Accredited Practising Dietitians provide expert Dietetics Services in Perth, helping clients — including those living in Supported Independent Living (SIL) Homes — understand and manage their nutrition needs to maintain optimal bone health at every stage of life.
Why Calcium Matters
Think of your bones as a savings account for calcium. Throughout your life, you “deposit” calcium into your bones through your diet. But when your body needs calcium for other essential functions (like helping your heart beat or muscles contract), it “withdraws” calcium from your bones.
If you’re not taking in enough calcium through food or supplements, your body continues to withdraw from this “bone bank.” Over time, this can cause your bone density to decline — putting you at higher risk for conditions like osteoporosis and bone fractures.
Calcium Requirements Through Different Stages of Life
Your calcium needs change as you grow. Children and teenagers need more calcium during growth spurts, while adults — especially women over 50 and men over 70 — require higher intakes to maintain bone mass and strength.
According to the National Health and Medical Research Council of Australia (NHMRC), here are the recommended daily calcium intakes:
| Category | Age (years) | Recommended Daily Intake |
|---|---|---|
| Children | 1–3 | 500 mg/day |
| Children | 4–8 | 700 mg/day |
| Girls and Boys | 9–11 | 1,000 mg/day |
| Teens | 12–18 | 1,300 mg/day |
| Adults (Men and Women) | 19+ | 1,000 mg/day |
| Women | Over 50 | 1,300 mg/day |
| Men | Over 70 | 1,300 mg/day |
Reaching your “peak bone mass” — the maximum bone density your body achieves — usually happens in your early twenties. Nearly 40% of bone mass is developed during puberty, which makes adequate calcium intake in childhood and adolescence essential.
After age 30, bone density gradually declines, but maintaining a balanced diet rich in calcium, vitamin D, and other nutrients can help slow this process and preserve strength.
How Calcium Supports Bone and Body Health
Calcium’s benefits go beyond just the bones. It contributes to:
- Healthy muscle function: allowing muscles to contract and relax properly.
- Efficient nerve transmission: supporting brain and nerve communication.
- Stable heart rhythm: helping maintain proper cardiovascular function.
Without enough calcium, the body prioritises these vital functions by drawing calcium from the bones — which can lead to bone weakness over time.
Sources of Calcium in Your Diet
Getting enough calcium doesn’t always mean relying on supplements. Many everyday foods are rich in calcium and can easily be part of a balanced diet.
Excellent sources include:
- Dairy foods: milk, yoghurt, and cheese
- Plant-based options: fortified soy milk, tofu with added calcium, almonds, and sesame seeds
- Fish: sardines and salmon (with bones)
- Leafy greens: kale, broccoli, and bok choy
- Fortified foods: cereals and orange juice with added calcium
For those who are lactose intolerant or follow plant-based diets, Accredited Practising Dietitians can help identify suitable alternatives and ensure you’re still meeting your calcium requirements.
Calcium Absorption and Vitamin D
Even if you’re eating calcium-rich foods, your body needs vitamin D to absorb it effectively. Vitamin D is produced when your skin is exposed to sunlight, but it can also be found in foods such as eggs, oily fish, and fortified dairy products.
Older adults often absorb calcium less efficiently and may lose more through the kidneys. Therefore, maintaining a balanced intake of both calcium and vitamin D is essential to keep bones strong and reduce the risk of osteoporosis.
Calcium Needs for Women and Older Adults
Women, particularly after menopause, experience a natural decline in estrogen levels, which accelerates bone loss. This makes calcium intake even more important. Women over 50 and men over 70 should aim for 1,300 mg of calcium per day to maintain bone density and reduce fracture risk.
In older adults, dietitians often recommend calcium-rich snacks throughout the day — such as yoghurt, cheese, or fortified milk — to make it easier to meet daily requirements without overwhelming meals.
