Vitamin D3 is naturally synthesized by humans in the skin when it is exposed to ultraviolet light, but under conditions of low light exposure, supplements offer a good source of vitamin D in order to maintain adequate levels. Vitamin D3 is the body’s preferred source of vitamin D and it helps considerably in improving the absorption of calcium by the body

Vitamin D and vitamin C play important roles in immune function, neuromuscular activity, cell growth and inflammation. Since Calcium cannot be made in the body, there is the need for intake of supplements in the right dose. Calcium aids blood, muscle and nerve functions. Generally, calcium requirements are higher during childhood, adolescence and during lactation. Calcium can be lost from the body largely through urine, faeces, breastfeeding and during pregnancy and in small quantities through hair, skin and sweat.

Majority (about 99%) of calcium in the body is found in the bones with smaller amount found in the teeth.

Vitamin C serves the following functions:

  • Vitamin C is needed with calcium because it helps to maintain the cartilage in bones and teeth.
  • It boosts the immune system.
  • It aids fast wound healing
  • It Makes protein that is essential for the ligaments, tendons and skin.

In pregnant and lactating women, calcium is lost through the development of foetus and breast feeding respectively. As a result, there is great demand for Calcium and vitamins D for pregnant women. Vitamin D supplements are recommended for all pregnant or breastfeeding women, babies and children aged six months to five years.

Also, since calcium is needed for bone formation, pregnant women, for them to be on the safer side, should take adequate amount calcium for proper bone formation in the body of the growing foetus.

The WHO (World Health Organization) recommends calcium to pregnant women to prevent pre-eclampsia.

*always consult your doctor before you take any medicines.


Vitamin D supplements are recommended for children aged six months to five years since at the age range, they are exposed little to the sun. Calcium is an important nutrient for all living cells in the body to remain viable. For children, calcium is important for tooth formation and for the formation and development of better bones (and consequently, better bone mass). A greater proportion of calcium is absorbed during periods of growth (since that is when bones are formed) than in adulthood. Better bones and proper bone mass in adulthood is a result of proper intake of calcium from infancy to adolescence.

Calcium deficiency in children can contribute or lead to the following in children:

  • Rickets: Rickets is a bone disease that is often due to severe calcium (and vitamin D) deficiency. The disease is characterized by severe bone deformities, especially in the legs and writs.
  • Osteoporosis (later in life): This is a medical condition in which the bones become brittle and fragile which is usually caused by deficiency in calcium or vitamin D or both.
  • Unhealthy Bone: When there is insufficient level of calcium in the body system, the body will have to extract it from the bones, giving rise to unhealthy bones.
  • Bone Fracture

The average adult skeleton contains 1200mg of calcium (which is equivalent to 2% of body weight) which provides rigidity. Calcium is essential for better bone growth. As adequate intake of calcium is one of a number of factors which are important for acquiring bone mass and attaining Peak Bone Mass (PBM). Diets containing insufficient amounts of calcium may lead to low bone which will in turn lead to health defect called osteoporosis. Studies have suggested that calcium may play an important role in reducing risk of cardiovascular diseases and weight management.

  • Calcium Deficiency and Brain Health
    Links between calcium deficiency and Alzheimer’s disease have been observed. The proper intake of calcium (with the right amount of Vitamin D) is a positive step to reduce the risks of Alzheimer’s disease.
  • Calcium Deficiency and Intestinal Health
    Celiac disease is an intestinal ailment that frequently involves less-than-optimal nutrients absorption. Calcium and vitamin D are often recommended for adults with celiac diseases.
  • Calcium Deficiency and Cardiovascular System
    It has been suggested that calcium deficiency contributes to the development of high blood pressure.
