Calcium is vital for building and maintaining strong, healthy bones.Most adults need 1,000 mg to 1,200 mg of calcium per day.Prioritize calcium-rich foods first, and consult a health care provider before taking supplements.<\/p>\n
Calcium is an essential mineral for bone health, giving your skeleton the strength and structure it needs to support you every day. Because bones are living tissue that constantly break down and rebuild, getting enough calcium is essential for keeping them resilient over time.\n<\/p>\n
\u201cOver 99% of the body\u2019s calcium is stored in the bones and teeth, and it serves as a building block for bone remodeling,\u201d says Umo Callins, M.S., RD, CSSD, CPT<\/a>. Without enough calcium in your diet, the body draws from its bone reserves to support critical functions like muscle movement and nerve signaling, which can gradually weaken bones.,\u00a0\n<\/p>\n In this article, we\u2019ll explore what happens to your bones when you get enough calcium, how much you need, the best food sources and when supplements may\u2014or may not\u2014be helpful.\n<\/p>\n Why We Love Calcium for Bone Health <\/p>\n Calcium is essential for strong, resilient bones that can handle the physical demands of daily life. As a key component of bone tissue, it helps bones support movement, absorb impact and adapt to activity throughout life. Getting enough calcium is particularly important in early adulthood, when the body is still building and reinforcing its skeletal foundation.\n<\/p>\n \u201cYour bones are constantly remodeling, which means they are repeatedly breaking down old bone and rebuilding new,\u201d says Callins. Adequate calcium helps support this process, giving bones the resources they need to withstand everyday wear and the changes that come with aging.\n<\/p>\n Research suggests that getting enough calcium in young adulthood may have lasting benefits. Studies show that both sufficient dietary calcium intake\u2014and, when necessary, supplementation\u2014between ages 20 and 35, when peak bone mass is still developing, can improve bone density and help reduce bone loss later in life<\/a>. Building a stronger skeletal reserve early on can provide long-term protection as natural bone breakdown accelerates with age.\n<\/p>\n Calcium continues to support bone health later in life, particularly during periods of accelerated bone loss, such as after menopause. As estrogen levels decline, bone breakdown can outpace bone formation. Calcium, often paired with vitamin D, may help slow declines in bone mineral density. That said, research in older adults is mixed, especially when it comes to calcium supplements<\/a>. While some studies show modest improvements in bone density with calcium or calcium-plus\u2013vitamin D supplements, others find little effect, particularly with fracture prevention.,\u00a0\n<\/p>\n Fortunately, calcium from food sources<\/a> like dairy products may help maintain or increase bone mineral density in adults over 50, especially when paired with other bone-supporting strategies like strength training.\n<\/p>\n Calcium Deficiency <\/p>\n About 38% of adults in the United States don\u2019t get enough calcium from their diet. When calcium intake is inadequate, the body draws the mineral from bones, gradually weakening them over time.\n<\/p>\n \u201cCalcium deficiency doesn\u2019t always show obvious symptoms early on, and unless someone takes certain tests, like bone density scans or blood tests, you might not even know you have a problem,\u201d says Bonnie Taub-Dix, RDN<\/a>. \u201cThis is particularly dangerous later on in life when you might see more bone loss, fractures, muscle cramps or weakness.\u201d\u00a0\n<\/p>\n Taub-Dix adds that meeting calcium requirements throughout the lifespan is essential, as inadequate intake during childhood and adolescence can also affect peak bone development.\n<\/p>\n How Much You Need <\/p>\n Calcium needs vary, but can generally are based on life stage and sex:\n<\/p>\n Adults ages 19\u201350: 1,000 milligrams per dayMen ages 51\u201370: 1,000 mg per dayWomen ages 51+: 1,200 mg per dayMen ages 71+): 1,200 mg per day<\/p>\n
