Calcium is used by the body to promote healthy and strong bones. Many people's diets are deficient in this nutrient, making it necessary for some to take supplements to meet their calcium needs. Those who are deficient in calcium may experience symptoms that can affect their daily lives or overall health. Calcium provides more than just strong bones; it can also improve nerve transmission and aid with muscle contractions around the heart, which can lead to better cardiovascular health and the improvement of heart-related conditions. For some, it may be beneficial to take calcium along with other supplements, such as vitamin D, that can increase the absorption rate.
Many adults are deficient in calcium, which can lead to health problems down the road. Women are more at risk of calcium deficiency than men, and it can lead to osteoporosis, a serious condition that can cause bone loss and weakened bones. Frequent muscle cramps, brittle nails and hair are often signs of calcium deficiency in adults. Left untreated, this can worsen and cause further problems.
Taking more calcium than recommended may also cause health problems. Calcium overdose may cause issues such as frequent urination, stone formation in the kidneys, muscle weakness and headaches. Other health problems may arise from excessive calcium in the body. Repeated calcium overdose often requires medical intervention and, in some cases, emergency care to remove calcium from the body or stomach.
As the human body does not produce calcium, it is important to eat a diet that has as close to the recommended amount of calcium per day as possible. Drinking milk and eating other dairy products are excellent ways to get calcium without the need for supplements, but for some this is not possible. Vegan or other restrictive diets may not permit dairy products, making obtaining calcium through other sources important. Some green vegetables provide calcium, but often a supplement is necessary.
