Most people know that Vitamin D can be obtained from sunlight hitting the skin, and that most of us who live in temperate climates typically do not get enough through sunlight, so it is supplemented through milk and cereals. It can also be obtained through eggs, fish and other animal products, but for vegans, it can be particularly tricky to get enough vitamin D and calcium.
Many people, particularly the elderly are deficient in Vitamin D. Vitamin D regulates bone health, as well as many other bodily functions. Deficiencies can cause bone problems, and as it is often forgotten, simply understanding that Vitamin D affected bone health basically eradicated rickets.
Researchers have developed a new test to determine the amounts of different forms of Vitamin D the body obtains from diet and sunlight, Vitamin D2 and D3 respectively. This will help doctors and researchers better determine Vitamin D deficiencies in people.
According to Professor Naughton, a lead researcher:
“Our new test can individually measure all the forms of vitamin D that matter, and potentially help us to understand exactly what is causing any deficiency. Perhaps people just need more sun, or maybe they should be looking much more closely at their diet too.”
The hope is that development will lead to further trials exploring Vitamin D deficiencies and its effect on other medical conditions such as cancer and multiple sclerosis.
