Vitamins & minerals health centre Vitamin D deficiency What is vitamin D deficiency? Vitamin D is essential for healthy bones. We get some of it from food, but most comes from sunlight. Some people don't have enough vitamin D - called vitamin D deficiency. Between October and March, the sunlight in Britain is not strong enough to make enough vitamin D, and up to a quarter of the population has low levels of it in their blood. Vitamin D is also found in oily fish, such as salmon, mackerel and sardines, eggs, fortified fat spreads, fortified breakfast cereals and powdered milk. However, it is hard to get enough of it just from food. Symptoms of vitamin D deficiency Vitamin D deficiency can put people at risk of: - Rickets bone problems in children - Osteomalacia bone problems in adults Some research suggests that not getting enough of it may also be linked to: Vitamin D deficiency at-risk groups The Chief Medical Officers of the UK say these groups are at particular risk of vitamin D deficiency: - Pregnant and breastfeeding women, especially teenagers and young women. - Infants and children under 5 years of age. - People 65 and over. - People who have little or no exposure to the sun. This includes covering-up for cultural reasons, people who are housebound or who stay indoors for long periods of time. - People with darker skin, such as African, African-Caribbean and South Asian origin. These groups are not able to make as much vitamin D as those with paler skin. Blood test for vitamin D deficiency The most accurate way to measure how much vitamin D is in your body is a blood test to measure 25-hydroxy vitamin D in your bloodstream. This is a form of vitamin D produced in the liver. In the kidney, 25-hydroxy vitamin D is converted into an active form of the vitamin for use by the body to help control calcium and phosphate levels. Safe sun exposure Around 10 to 15 minutes a day in the summer sun without sunscreen is enough to top up vitamin D levels for most people. Health officials don't give firm recommendations on the duration because the ideal amount of sun depends on people's skin type and how quickly they get sun burn. People with darker skin need longer in the sun than those with lighter skin. The best time of day for making vitamin D from sunlight is 11am to 3pm, April to September. It doesn’t require putting on a bikini or trunks, but the larger the area of the body uncovered, the more of the vitamin the body makes. Other than a daily vitamin top-up, the usual sun protection measures should be taken, including using sun protection factor of at least SPF 15. However this will not provide sufficient vitamin D during the winter months.

Vitamin D je važan za zdravlje kostiju – Malo detaljnije o vitaminu D Vitamin D važan je za zdravlje vaših kostiju i zuba, jer on održava balans između koncentracije kalcija i fosfora te stimulira formiranje kostiju, a uz tosmanjuje rizik od kardiovaskularnih bolesti i karcinoma. Saznajte koja je optimalna dnevna količina vitamina D, kako ga unosite u organizam i što ako ga nedostaje? Dnevna količina vitamina D koja je potrebna čovjeku je od 400 mjernih jedinica za djecu do 1.200 za odrasle. Naime, ako organizam ne dobiva tu količinu vitamina može doći i do ozbiljnih oboljenja kostiju. Nedostatak vitamina D čest je kod starijih osoba, a taj gubitak kod ljudi u godinama povezuje se sa pojavom rizika obolijevanja od osteoporoze, bolesti koju karakterizira gubitak koštane mase. Vitamin D može se unijeti sunčanjem u trajanju od 10 do15 minuta dnevno, između 11 i 14 sati, bez nanošenja preparata za sunčanje na ruke i lice, a rizik za manjak ovog vitamina imaju osobe koje žive u hladnim krajevima, starije osobe i bebe, jer u majčinom mlijeku nema dovoljno vitamina D. >> Vitamini i njihova uloga u organizmu Jedan od načina unošenja vitamina D je i ishrana obogaćena lososom, kao i korištenje ribljeg ulja.
