What is Calcium Requirement?

Calcium is an essential mineral, and a major constituent of bones and teeth. It plays a central role in healthy functioning of your nervous system, controls muscle contraction, and secretion of hormones, such as insulin. Our bodies do not produce calcium, hence we must get it through dietary sources. Calcium deficiency may result in bone loss and osteoporosis.\n\nCalcium metabolism refers to a series of biochemical processes to maintain and regulate the calcium level in blood. The state of calcium metabolism affects your calcium requirement, which is regulated by three main mechanisms, which are calcium absorption in your intestines, calcium reabsorption in your kidneys and bone turnover. \n\nGenetic variations in several key genes have been found to be associated with lower levels of calcium.\n\nThe RDA for adults is 1,000mg per day. It increases to 1,200mg per day for those over 50 years old. Other factors that may increase your chances of calcium deficiency include excessive alcohol consumption, premenstrual symptoms, vitamin D deficiency and magnesium deficiency.

Factors affecting Calcium deficiency

Although Calcium deficiency may be uncommon, you may need extra calcium if you are:


Food Sources Containing Calcium

Suggested Lifestyle Changes

Dietary Recommendations:

  1. Maintain healthy calcium levels through your diet.Milk and dairy products, fish with edible bones e.g. sardines and anchovies, beans and bean products, fortified soya milk, green leafy vegetables such as kai lan, chye sim, bok choy, calcium fortified cereals and bread are good sources of calcium.
  2. Combining foods containing calcium and vitamin D optimises calcium absorption. Some examples are vitamin D fortified cereal with calcium fortified soy milk, or calcium enriched bread with salmon.
