Calcium is a vital nutrient required to maintain the strength of teeth and bones, vascular contraction and vasodilation, muscle formation, nerve transmission, intracellular signaling, and hormonal secretion. Most of the body’s calcium supply is stored in the teeth and bones, thereby supporting their structure and function. 1% is serum calcium, which is stored in blood, muscles and body fluids, which is used in the aforementioned metabolic functions.
The Institute of Medicine has recommended the amount of dietary calcium intake for various age groups:
- 200 mg for infants up to 6 months,
- 260 mg for infants of 7 to 12 months,
- 700 mg for 1 to 3-year-old children,
- 1000 mg for 4 to 8-year-old children
- 1300 mg for 9 to 13 year age group
- 1000 mg for adults
- 1200 mg for females above 50 years of age
Calcium deficiency results from inadequate amounts of calcium in the body. It occurs due to inadequate consumption of calcium over a prolonged period of time. Further, it can also be caused due to deficiency of vitamin D, phosphorus and magnesium, which help in calcium absorption.
calcium plays a crucial role in the functioning of the body and the deficiency of the same can lead to a whole series of problems. These problems not only hamper the functioning but can actually prove to be a threat under the most significant circumstances. Fatigue and weakness, muscle cramps, dry skin, and brittle nails, late puberty, tooth decay, frequent fractures, and bone breakage, insomnia are some of the symptoms of calcium deficiency. Calcium deficiency may lead to osteoporosis, cardiovascular diseases, high blood pressure, and cancer. Hence, timely prevention and treatment of calcium deficiency are very important.
