Vitamin D is essential for the development and maintenance of bone, both for its role in assisting calcium absorption from food in the intestine and for ensuring the correct renewal and mineralisation of bone tissue. Vitamin D is made in the skin when it’s exposed to ultraviolet B rays. However, how much vitamin D is produced from sunlight depends on the time of day, where a person lives in the world and the colour of their skin. Lacking in the vitamin could create a very serious condition.

Vitamin D helps the intestines absorb calcium from the food one eats. Getting enough of both nutrients is an important part of making sure bones are dense and strong.
Unlike calcium, which is only absorbed by food the body makes vitamin D when sunlight hits the skin.
Not having sufficient sunlight or not eating the correct foods, will create problems with the bones and if suffering from an extreme deficiency, osteoporosis may develop.
Vitamin D is just as important for keeping bones strong and preventing the bone disease osteoporosis.

What does the study say?
In a study with the US National Library of Medicine National Institutes of Health, the effect of vitamin D on bone and osteoporosis was analysed.
The study noted: “The main effect of the active vitamin D metabolite is to stimulate the absorption of calcium from the gut.
“The consequences of vitamin D deficiency are secondary hyperparathyroidism and bone loss, leading to osteoporosis and fractures, mineralisation defects, which may lead to osteomalacia in the long term and muscle weakness causing falls and fractures.”

What the experts said?
Harvard Health said: “There is a large group of people who are likely to be deficient in vitamin D.
“It includes people with eating disorders; people who have had gastric bypass surgeries; those with malabsorption syndromes like celiac sprue, pregnant and lactating women; people who have dark skin; and those who wear total skin covering.
“In addition, people with or at risk for low bone density should discuss whether they need supplements and to have blood levels of vitamin D monitored.”
Vitamin D is naturally present in few foods but may be taken as a supplement. It is also produced by the body when exposed to the sun’s ultraviolet rays.
Many people, however, have low levels of vitamin D and need a supplement to help them reach recommended levels.
Supplementation of vitamin D has been shown to slow bone loss and reduce fracture, particularly when taken with calcium.
