As we age, our bones become weaker, which can lead to conditions like osteoporosis. However, there are steps we can take to maintain strong, healthy bones, and getting enough calcium is crucial to this process.
Calcium is a mineral that is essential for building and maintaining strong bones. Without enough calcium, bones can become brittle and more prone to fractures. Additionally, calcium plays a role in muscle function, nerve function, and blood clotting.
To ensure that you are getting enough calcium for your bones, it is important to consider your dietary intake and absorption of the mineral. In the next sections, we will discuss the various sources of calcium, how to maximize absorption, the benefits and risks of calcium supplements, and lifestyle changes that can help improve bone health.
Sources of Calcium
Calcium is an essential nutrient that is necessary for strong and healthy bones. While many people associate calcium with dairy products, there are actually various sources of calcium that can be incorporated into a balanced diet.
Some of the best dietary sources of calcium include:
| Food | Serving Size | Calcium Content |
|---|---|---|
| Low-fat yogurt | 1 cup | 415 mg |
| Sardines | 3 oz. | 325 mg |
| Kale | 1 cup, cooked | 177 mg |
| Almonds | 1/4 cup | 95 mg |
Other sources of calcium include fortified cereals, soy products, and certain types of fish, such as salmon and tuna. Additionally, calcium supplements can be taken to help increase calcium intake.
The recommended daily calcium intake varies by age and gender. According to the National Institutes of Health, the recommended daily intake for adults is:
- 1,000 mg for adults aged 19-50
- 1,200 mg for women over 50 and men over 70
- 1,000 to 1,300 mg for children and adolescents, depending on age
Incorporating calcium-rich foods into meals and snacks and considering a calcium supplement can help ensure you reach your recommended daily intake and support strong, healthy bones.
Calcium Absorption
Calcium is only useful if the body can absorb it efficiently. The body can only absorb a certain amount of calcium at one time, and factors like vitamin D and magnesium can affect absorption.

It’s important to note that taking too much calcium at once – particularly from supplements – can actually hinder absorption. This is why it’s recommended to spread out calcium intake throughout the day.
Calcium Supplements
Calcium supplements can be an effective way to increase your calcium intake if you’re not getting enough through your diet. There are several types of calcium supplements available:
| Calcium supplement | Advantages | Disadvantages |
|---|---|---|
| Calcium carbonate | High in calcium, easy to find, affordable | May cause constipation, needs to be taken with food for best absorption |
| Calcium citrate | Easy to absorb, can be taken with or without food | May be more expensive, lower in elemental calcium per pill |
| Coral calcium | May contain other minerals beneficial to bone health | Expensive, not well-studied |
It’s important to note that calcium supplements should be taken in moderation and with a doctor’s guidance, especially for those at risk for kidney stones or with certain medical conditions.
It’s also recommended to pair calcium supplements with vitamin D, which helps with calcium absorption. Look for supplements that combine calcium and vitamin D for maximum bone-strengthening benefits.

Lifestyle Changes for Better Bone Health
Aside from increasing your calcium intake, there are other lifestyle changes you can make to improve your bone health.
Exercise
Regular exercise is crucial for building and maintaining strong bones. Weight-bearing exercises, such as walking, jogging, and strength training, can help stimulate bone growth and increase bone density.
| Recommended exercises: | Walking | Jogging | Strength training |
|---|---|---|---|
| Frequency: | At least 30 minutes a day, most days of the week | At least 30 minutes a day, most days of the week | 2-3 times a week |
Quit smoking
Smoking has been linked to decreased bone density and an increased risk of fractures. If you smoke, quitting can help improve your bone health and reduce your risk of developing osteoporosis.
Reduce alcohol intake
Drinking alcohol in excess can weaken bones and increase the risk of fractures. If you drink alcohol, it’s recommended to do so in moderation.
Maintain a healthy weight
Being underweight can increase your risk of developing osteoporosis, while being overweight can put extra strain on your bones. Maintaining a healthy weight through diet and exercise can help reduce your risk of bone-related issues.
By making these lifestyle changes, you can improve your bone health and reduce your risk of bone-related issues.
Calcium and Osteoporosis
Osteoporosis is a condition where bones become weak and brittle, increasing the risk of fractures. Calcium is a crucial nutrient for maintaining bone density, making it essential for preventing osteoporosis.
The recommended daily calcium intake for adults is between 1000-1200 mg per day, depending on age and gender. However, many people do not get enough calcium through their diet alone.
| Factors affecting calcium absorption | |
|---|---|
| Vitamin D | Helps the body absorb calcium |
| Magnesium | Needed for calcium to be incorporated into bone |
It’s important to get enough vitamin D and magnesium to ensure optimal calcium absorption and bone health.
Preventing osteoporosis through lifestyle changes is also crucial. Regular exercise, particularly weight-bearing exercise, can help improve bone density. Quitting smoking and reducing alcohol intake can also help protect bone health.
If you’re concerned about your calcium intake or risk of osteoporosis, talk to your doctor or a registered dietitian for personalized advice and recommendations.
Calcium for Children and Adolescents
Calcium is especially important for children and adolescents because these are the years when bones are still growing and developing. Getting enough calcium during this time can help prevent osteoporosis later in life.
The recommended daily intake of calcium for children and adolescents varies depending on their age. For infants up to 6 months old, the recommended intake is 200 mg per day. For age 7 months to 1 year, it increases to 260 mg per day. For ages 1 to 3 years, it’s 700 mg per day, and for ages 4 to 8 years, it’s 1000 mg per day. For ages 9 to 18 years, males and females need to consume 1300 mg per day.
Fortunately, there are many ways to incorporate calcium-rich foods into a child’s diet. Dairy products like milk, cheese, and yogurt are excellent sources of calcium. Leafy greens like spinach and kale are also high in calcium, as are canned fish like salmon and sardines. Some fortified foods like cereal and orange juice can also be good sources of calcium.
It can be challenging to get children to eat a calcium-rich diet, especially if they are picky eaters. Parents can encourage their children to eat calcium-rich foods by making them fun and appealing. For example, try making a calcium-rich smoothie or adding leafy greens to a favorite pasta dish.
If a child is not getting enough calcium through their diet, a supplement may be necessary. However, it’s important to talk to a healthcare provider before giving a child a calcium supplement to determine the appropriate dosage and ensure it’s safe for them to take.
Calcium and Pregnancy
Calcium is essential for both the mother and developing baby during pregnancy. It plays an important role in the development of the baby’s bones, teeth, heart, nerves, and muscles. Pregnant women need to consume enough calcium to ensure that their own bone health is not compromised, as the developing baby will draw calcium from the mother’s bones if necessary.
The recommended daily intake of calcium during pregnancy is 1,000 milligrams per day for women aged 19 to 50 years old. Pregnant teens (ages 14 to 18) need slightly more calcium, at 1,300 milligrams per day, as their bodies are still growing and developing.
Calcium can be obtained through food sources such as dairy products, leafy greens, fortified plant-based milks, and fortified cereals. It is also available in supplement form, but pregnant women should consult with their healthcare provider before taking any supplements to ensure they are taking a safe and appropriate dosage.
In addition to consuming enough calcium, pregnant women should also ensure they are getting enough vitamin D, which enhances calcium absorption. Some good food sources of vitamin D include fatty fish, eggs, and fortified foods. Prenatal vitamins should also contain adequate amounts of calcium and vitamin D.
It is important for pregnant women to maintain a healthy and balanced diet throughout their pregnancy to ensure they are getting all of the necessary nutrients for themselves and their developing baby. If you have any concerns about your calcium or nutrient intake during pregnancy, speak with your healthcare provider.
