As we age, maintaining strong bones and muscles becomes increasingly important — and two key nutrients play a central role: calcium and vitamin D.
From around the age of 50, the body becomes less efficient at absorbing nutrients and maintaining bone density. This makes it even more important to ensure you’re getting enough of both.
Why Calcium Is Important as You Age
Calcium is the main mineral found in your bones and teeth, and it plays a vital role in several essential functions.
Key Benefits of Calcium
- Maintains bone strength
Helps slow the natural loss of bone density that occurs with age - Reduces fracture risk
Adequate calcium intake lowers the likelihood of fractures, particularly in the hips and spine - Supports muscle function
Essential for muscle contraction — low levels can contribute to weakness or cramps - Supports heart and nerve function
Helps regulate heartbeat and nerve signalling
👉 If your calcium intake is too low, your body may start drawing calcium from your bones — weakening them over time.
Why Vitamin D Is Essential
Vitamin D is just as important as calcium — because without it, your body cannot properly absorb and use calcium.
Key Benefits of Vitamin D
- Improves calcium absorption
Ensures the calcium you consume is actually used by the body - Supports bone density
Helps prevent osteoporosis (brittle bones) - Improves muscle strength and balance
Low levels are linked to increased risk of falls - Supports immune function
Plays a role in maintaining overall health
Why Calcium and Vitamin D Are More Important After 50
As you get older, several changes increase your risk of bone loss:
- Bone loss accelerates
Especially after menopause in women - Reduced vitamin D production
The skin becomes less efficient at producing vitamin D from sunlight - Lower absorption of nutrients
The digestive system may absorb calcium less effectively - Higher risk of fractures
Falls and bone fragility become more common
👉 This makes maintaining adequate intake essential for long-term health and independence.
How Much Calcium and Vitamin D Do You Need?
Typical daily guidance:
- Calcium: ~1,000–1,200 mg per day (from food and supplements)
- Vitamin D: ~800–1,000 IU per day (higher if deficient — check with a professional)
👉 Needs can vary depending on diet, lifestyle and health status.
Best Food Sources
Calcium-Rich Foods
- Dairy products (milk, yoghurt, cheese)
- Fortified plant milks
- Tofu
- Leafy green vegetables
- Almonds
Vitamin D Sources
- Oily fish (salmon, mackerel, sardines)
- Fortified foods
- Sunlight exposure
👉 In the UK, sunlight is often insufficient in winter — making vitamin D intake particularly important.
Should You Take Supplements?
You may benefit from supplements if:
- You have limited sun exposure
- Your diet is low in calcium-rich foods
- You have been diagnosed with low bone density
- You are at higher risk of osteoporosis
👉 However, supplements should support — not replace — a balanced diet.
Getting the Balance Right
Calcium and vitamin D work together.
- Taking calcium without vitamin D reduces effectiveness
- Taking excessive amounts of either can cause problems (e.g. kidney stones)
👉 Balance and appropriate intake are key.
Calcium, Vitamin D and Healthy Ageing
Supporting bone and muscle health is essential for maintaining independence and quality of life as you age.
Alongside a balanced diet (such as the Mediterranean diet) and regular physical activity, these nutrients play a central role in long-term wellbeing.
The Bottom Line
Calcium and vitamin D are essential nutrients for healthy ageing.
As you move beyond 50, focusing on adequate intake can help:
- Maintain bone strength
- Support muscle function
- Reduce fracture risk
Simple changes to your diet and lifestyle can make a significant difference over time.
Frequently Asked Questions
Do you need more calcium after 50?
Yes, bone loss increases with age, so maintaining adequate calcium intake becomes more important.
Can you get enough vitamin D from sunlight?
In the UK, sunlight alone is often not enough — especially in autumn and winter.
Is it better to get calcium from food or supplements?
Food sources are preferred, but supplements can help if intake is low.
What happens if you don’t get enough calcium or vitamin D?
Low levels can lead to weaker bones, increased fracture risk and muscle weakness.
