Most of us think that sun-worshippers get plenty of vitamin D, the so-called “sunshine vitamin”. But deficiencies, which can weaken the immune system and increase the risk of cancer and osteoporosis, can also be caused by a patient’s diet. Now, for the first time, a new blood test can accurately reveal the different types of vitamin D the body absorbs from diet and sunshine, known as vitamins D2 and D3, respectively. A team at Kingston University, headed by Professor Declan Naughton, spent five months developing the new test.
Another type of the vitamin can be found in foods such as salmon, mackerel, sardines and egg yolks. 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.
