Calcium is best known for building strong bones and teeth, but it also supports normal muscle function, nerve signalling and blood clotting. Because the body cannot make calcium, you need to obtain it consistently from food\u2014and, when your diet falls short, a carefully chosen supplement may help close the gap.<\/p>\n\n
The goal is not to consume as much calcium as possible. Good bone health depends on getting an appropriate total amount from food and supplements, along with vitamin D, protein, regular weight-bearing activity and healthy lifestyle habits.<\/p>\n\n
Calcium requirements vary by age and sex. The following reference amounts are based on the US National Institutes of Health calcium guidance<\/a> for generally healthy people:<\/p>\n\n
| Life stage<\/th> | Recommended calcium intake<\/th><\/tr>\n<\/thead>\n |
|---|---|
| Children 4\u20138 years<\/td> | 1,000 mg daily<\/td><\/tr>\n |
| Children and teens 9\u201318 years<\/td> | 1,300 mg daily<\/td><\/tr>\n |
| Adults 19\u201350 years<\/td> | 1,000 mg daily<\/td><\/tr>\n |
| Men 51\u201370 years<\/td> | 1,000 mg daily<\/td><\/tr>\n |
| Women 51\u201370 years<\/td> | 1,200 mg daily<\/td><\/tr>\n |
| Adults over 70 years<\/td> | 1,200 mg daily<\/td><\/tr>\n<\/tbody>\n<\/table>\n\n These figures represent your total daily intake<\/strong>, including calcium from meals, drinks and supplements. Individual needs can differ, especially during pregnancy, after menopause or when a medical condition affects bone or kidney health. A healthcare professional can help determine the right target for you.<\/p>\n\n A food-first approach provides calcium together with other nutrients. Useful sources include:<\/p>\n\n Check nutrition labels because calcium content can vary considerably between brands and products. For example, not every type of tofu or plant-based drink contains the same amount.<\/p>\n\n A supplement may be worth considering when you regularly fall short through food\u2014for example, if you avoid dairy, eat very little, have increased needs or have been advised to supplement by a healthcare professional. Supplements should usually fill the gap<\/strong> between your diet and your target, rather than replace calcium-rich foods.<\/p>\n\n A simple first step is to estimate the calcium in a typical day of eating. If your diet supplies approximately 700 mg and your target is 1,000 mg, you may need to discuss only the remaining gap rather than taking a large dose automatically.<\/p>\n\n When comparing calcium products, focus on practical details rather than a \u201cmore is better\u201d approach:<\/p>\n\n The label should state how much actual, or elemental<\/em>, calcium each serving provides. This is the figure that counts towards your daily total\u2014not simply the weight of the entire calcium compound.<\/p>\n\n Calcium carbonate and calcium citrate are common forms. Calcium carbonate is generally taken with food, while calcium citrate is less dependent on stomach acid. Other formulations are also available. The most suitable option depends on the serving size, tolerability, diet and personal health needs.<\/p>\n\n Calcium absorption from supplements is generally highest at doses of 500 mg or less at one time<\/strong>. If a healthcare professional recommends a larger supplemental amount, dividing it between meals may be more appropriate.<\/p>\n\n Vitamin D supports active calcium absorption in the gut. Bone health also depends on adequate protein, physical activity\u2014particularly resistance and weight-bearing exercise\u2014and avoiding smoking and excessive alcohol.<\/p>\n\n A supplement only helps if it fits your routine. Consider the number and size of tablets or capsules, directions for use and whether the formula is comfortable for your digestive system.<\/p>\n\n |
