How much calcium does a woman need a day
The foods we eat contain a variety of vitamins, minerals, and other important nutrients that help keep our bodies healthy. Two nutrients in particular, calcium and vitamin D, are needed for strong bones. Calcium is needed for our heart, muscles, and nerves to function properly and for blood to clot. Inadequate calcium significantly contributes to the development of osteoporosis. Many published studies show that low calcium intake throughout life is associated with low bone mass and high fracture rates. National nutrition surveys have shown that most people are not getting the calcium they need to grow and maintain healthy bones.

How much calcium is too much?
The information included here will help you learn all about calcium and vitamin D — the two most important nutrients for bone health. Calcium is a mineral that is necessary for life. In addition to building bones and keeping them healthy, calcium enables our blood to clot, our muscles to contract, and our heart to beat.
Every day, we lose calcium through our skin, nails, hair, sweat, urine and feces. Our bodies cannot produce its own calcium. This is fine once in a while, but if it happens too often, bones get weak and easier to break. Too many Americans fall short of getting the amount of calcium they need every day and that can lead to bone loss, low bone density and even broken bones.
The amount of calcium you need every day depends on your age and sex. Food is the best source of calcium. Dairy products, such as milk, yogurt, and cheese are high in calcium. Certain green vegetables and other foods contain calcium in smaller amounts.
Some juices, breakfast foods, soymilk, cereals, snacks, breads and bottled water have added calcium. If you drink soymilk or another liquid that is fortified with calcium, be sure to shake the container well as calcium can settle to the bottom. A simple way to add calcium to many foods is to add a single tablespoon of nonfat powdered milk, which contains about 50 mg of calcium. It is easy to add a few tablespoons to almost any recipe. To determine how much calcium is in a particular food, check the nutrition facts panel for the daily value DV.
Food labels list calcium as a percentage of the DV. This amount is based on 1, mg of calcium per day. For example:. The amount of calcium you need from a supplement depends on how much you get from food. Try to get the daily amount recommended from food and only supplement as needed to make up any shortfall. There is no added benefit to taking more calcium than you need.
Doing so may even carry some risks. Calcium supplements are available without a prescription in a wide range of preparations including chewable and liquid and in different amounts. The best supplement is the one that meets your needs for convenience, cost, and availability.
When choosing a supplement, keep the following in mind:. Vitamin D plays an important role in protecting your bones, both by helping your body absorb calcium and by supporting muscles needed to avoid falls. Children need vitamin D to build strong bones, and adults need it to keep their bones strong and healthy. Your skin makes vitamin D in reaction to sunlight and stores it in fat for later use. How much vitamin D your skin can produce depends on time of day, season, latitude, skin pigmentation, age, and other factors.
There are many reasons people do not have enough vitamin D. As we age, our skin loses its ability to generate vitamin D. People who live in cities or in institutional settings like nursing homes spend too little time outdoors. Even people who spend time outdoors often use sunscreen to prevent skin cancer.
Sunscreen with an SPF as low as 8 reduces vitamin D production by 95 percent. Vitamin D is found in very few foods. Sources include fatty fish like wild-caught mackerel, salmon, and tuna. Vitamin D is added to milk and other dairy products, orange juice, soymilk, and fortified cereals. Check the food label to see if vitamin D has been added to a particular product.
It is very difficult to get all the vitamin D you need from food alone. Most people must take vitamin D supplements to get enough to support bone health. Before adding a vitamin D supplement, check to see if any of the other supplements, multivitamins, or medications you take contain vitamin D. Many calcium supplements also contain vitamin D. There are two types of vitamin D supplements.
They are vitamin D2 ergocalciferol and vitamin D3 cholecalciferol. Both types are good for bone health. Vitamin D supplements can be taken with or without food and the full amount can be taken at one time. While your body needs vitamin D to absorb calcium, you do not need to take vitamin D at the same time as a calcium supplement.
If you need help choosing a vitamin D supplement, ask your healthcare provider or pharmacist to recommend one. To figure out how much vitamin D you need from a supplement, subtract the total amount of vitamin D you get each day from the recommended total daily amount for your age.
For example, a year-old woman who gets IU of vitamin D from her calcium supplement should take between and additional IU of vitamin D to meet the — 1, IU recommended for her age. Vitamin D deficiency occurs when you are not getting the recommended level of vitamin D over time.
Certain people are at higher risk for vitamin D deficiency, including:. Talk to your healthcare provider if you have any of these risk factors. If you have osteoporosis and also have a vitamin D deficiency, your healthcare provider may temporarily prescribe a high dose of vitamin D to bring you up to a healthy level.
