Why the body needs calcium?
Calcium is the most abundant mineral in the body. More than 98% of human skeleton consist of calcium. Calcium plays an important role in bone and teeth health. It also affects your muscles, hormones, nerve function, and ability to form blood clots.
The recommended daily intake of calcium is 1,000 to 1,300 milligrams per day for people ages 9 and up. In case of pregnant women, the calcium intake needs to be increased from 800mg a day to 1100mg a day. That’s an extra 300mg calcium a day (equivalent to 1 serve of a calcium-rich food). Pregnant women need to eat around 4 serves of calcium-rich foods every day to meet their needs.
Functions of Calcium
- The human body uses 99 percent of its calcium to keep your bones and teeth strong.
- Calcium also helps in cell signaling, blood clotting, muscle contraction and nerve function.
- Cells use calcium to activate certain enzymes, transport ions across the cellular membrane, and send and receive neurotransmitters during communication with other cells.
- Calcium helps in maintaining a regular heartbeat.
- Calcium helps in regulating blood pressure.
- Adequate intake of calcium over time seemed to reduce PMS symptoms, including anxiety, irritability, depression, headaches, and cramps.
- Calcium helps in losing weight.
- Calcium may decrease the risk for colorectal cancer.
- Calcium decreases the risk for osteoporosis.
- Without vitamin D, your body cannot absorb calcium.
Consuming too much calcium, especially in the form of calcium supplements, can lead to constipation and kidney stones. Caffeine, alcohol and excess sodium can all decrease calcium absorption and/or increase calcium excretion from your body.
Deficiency of calcium can increase the risk of developing diseases like osteoporosis, osteopenia, and calcium deficiency disease (hypocalcemia). The hormone disorder hyperparathyroidism may also cause calcium deficiency disease. Some of the causes for calcium deficiency include low levels of vitamin D, which makes it harder to absorb calcium, too much potassium which can burn up calcium and medications, such as those for thyroid replacement.
Calcium deficiencies can affect all parts of the body, resulting in weak nails, slower hair growth, and fragile, thin skin. Some of the symptoms of calcium deficiency disease include:
- confusion or memory loss
- muscle spasms
- numbness and tingling in the hands, feet, and face
- muscle cramps
- weak and brittle nails
- easy fracturing of the bones
