If you're trying to up your calcium intake, it's likely you already know that it's smart to increase the amount of low-fat dairy in your diet. That being said, dairy isn't the only way to get the calcium your body needs to thrive. Plenty of fruits and vegetables are also high in calcium, making it easier to get the recommended amount without relying on supplements. Here, we'll take a look at why calcium matters, and how you can get the calcium that you need from the produce section.
Why calcium matters
Calcium is vital for your overall health and well-being, especially when it comes to maintaining strong bones and teeth. The role of calcium in your body goes far beyond building and keeping strong bones, however.
Calcium helps your body maintain proper muscle function, as it allows your muscles to contract and relax smoothly. This is important for voluntary movements (like standing up, walking, and exercising) but it's also key for involuntary movements, such as the contractions that create your heartbeat.
The nervous system needs calcium to function properly as well. Calcium helps the body transmit signals between the brain and the body, ensuring that your body is working as one coordinated unit. The mineral also helps blood clot when you get a cut and supports the release of hormones and enzymes that help to regulate bodily functions.
Is it better to get calcium from food than from supplements?
While supplementation is one way to add calcium to your body, it's better to get the mineral from a nutrient-rich, whole foods diet. According to Dr. Erin Michos, the director of preventive cardiology at Johns Hopkins Ciccarone Center for the Prevention of Heart Disease, "A nutrient in pill form is not processed in the body the same way as it is when ingested from a food source." Dr. Michos says that research on whether calcium supplements are effective is inconclusive at best. "There is a growing body of evidence that suggests no health benefit, or even worse, that calcium supplements may be harmful," says Dr. Michos.
It's recommended that adults ages 19-50 should get at least 1000 mg of calcium from food sources each day. Women ages 51-70 should get at least 1,300mg each day, and men over the age of 70 should also up their intake to at least 1,300 each day.

How calcium can help you feel your best
As we mentioned calcium is necessary for building and maintaining strong skeletal health, but the mineral does far more in our bodies than it gets credit for. Let's explore some of the health conditions you may be able to improve by increasing your calcium intake.
Osteoporosis
Bone loss begins around age 30, and the process continues to speed up with age. Eating foods rich in calcium (specifically in combination with foods rich in vitamin D) can help prevent menopause-related bone loss in women, and it may also help to prevent bone loss in men.
Premenstrual Syndrome (PMS)
Research has shown that increasing calcium intake to 1,200mg per day showed a decrease in symptoms, including headaches, muscle aches, bloating, and food cravings.
High Blood Pressure
As we mentioned, getting enough calcium in your diet can help to support heart health. If you don't get enough calcium, you may be more likely to develop high blood pressure (hypertension). Early research shows that calcium may play a role in reversing hypertension. If you're currently taking blood pressure medication and want to try adding more calcium to your diet, do not stop taking your medication, and talk with your doctor if your goal is to eventually get off of your high blood pressure medication.
Obesity
Both animal and human studies have shown that low-fat dairy can play a role in reducing body weight. Researchers are still unsure as to whether this is due to calcium, other nutrients, or a combination of factors.
High Cholesterol
Early studies have shown that increasing calcium intake to 1,500mg to 2,000mg per day may help to lower cholesterol levels. It's important to note that this appears to have the greatest effect when used in tandem with regular exercise and a healthy diet, and it's possible that calcium works better to help people maintain existing normal cholesterol levels rather than helping people lower high cholesterol. If you have high cholesterol, talk with your doctor about the lifestyle changes you can make to lower your numbers.
Stroke Risk
A population-based study showed that women who ingested higher amounts of calcium were less likely to experience strokes over time than those who did not take in more calcium. If you're at risk of stroke, talk with your healthcare provider about the lifestyle changes you can make to reduce your risk.
The bottom line: Getting plenty of calcium from food can help to decrease your risk of developing certain health conditions, and may help to reduce symptoms of or eliminate other conditions, like osteoporosis. If you're living with the conditions listed above, talk with your doctor about whether increasing your calcium levels might help to improve your health.
