Calcium & Vitamin D: A Guide to Supporting Bone Health
Calcium and vitamin D work together to help keep bones strong, support muscle function, and promote overall health.
Think of:
🦴 Calcium = builds bones
☀️ Vitamin D = helps your body absorb calcium
Without enough vitamin D, your body may only absorb a small portion of the calcium you eat — making both nutrients important partners in bone health.
Remember: always consult with your healthcare provider first before starting any new supplements, including over-the-counter products. Individual needs vary.
Why These Nutrients Matter
Getting enough calcium and vitamin D may help:
✔ Maintain strong bones
✔ Support balance and muscle strength
✔ Lower risk of bone loss over time
These nutrients are especially important as we age, since bone density naturally decreases over time.
How Much Do You Need?
Daily needs vary by age.
Calcium Needs
Most adults need:
- Females 51-70 years: ~1,200 mg daily
- Males 51-70 years: ~1,000 mg daily
- 70+ years: 1,200mg daily
This includes calcium from both food and supplements.
Vitamin D Needs
Most adults need:
- 51-70 years: ~600 IU daily
- Age 70+: ~800 IU daily
Vitamin D helps your body absorb calcium effectively.
Food Sources of Calcium
Try including calcium-rich foods such as:
🥛 Milk, yogurt, cheese
🥬 Leafy greens (kale, collards)
🐟 Sardines or canned salmon with bones
🌱 Tofu (calcium-set)
🥜 Almonds
🥣 Fortified cereals or plant-based milks
Food Sources of Vitamin D
Vitamin D is harder to get from food alone, but can be found in:
🐟 Fatty fish (salmon, tuna)
🥚 Egg yolks
🥛 Fortified milk or dairy alternatives
🥣 Fortified cereals
Your body also produces vitamin D when skin is exposed to sunlight — though this decreases with age and varies by lifestyle and location.
Tips for Getting Enough
Build Calcium Into Meals
- Add yogurt to breakfast
- Include leafy greens at lunch
- Choose calcium-fortified options when available
Support Vitamin D Intake
- Include fortified foods regularly
- Spend brief time outdoors when appropriate
- Discuss supplementation if recommended by your provider
Pair Them Together
Calcium is absorbed best when vitamin D levels are adequate.
Supplement Considerations
Some people may need supplements — especially if:
- Dietary intake is low
- Sun exposure is limited
- Bone health risk is increased
Important safety notes:
- For adults over 50 years old:
- Total calcium intake should generally not exceed 2,000 mg daily
- Vitamin D intake should generally not exceed 4,000 IU daily
Too much of either can increase the risk of side effects such as kidney stones. Always consult with your healthcare provider first before starting any new supplements, including over-the-counter products.
Lifestyle Tips That Support Bone Health
Along with nutrition:
✔ Stay physically active
✔ Include strength or weight-bearing movement
✔ Limit smoking and excess alcohol
Healthy habits support how your body uses calcium.
When to Talk to Your Healthcare Provider
Always check with your provider before taking supplements, and especially if you:
- Have kidney disease
- Take medications that affect bone health
- Have a history of kidney stones
- Are unsure about your intake levels
Supplement needs vary from person to person.
