Osteoporosis health centre Vitamin D for osteoporosis Having enough vitamin D from sunlight and food in a healthy balanced diet is an important part of protecting bone health and helping to prevent conditions like osteoporosis. Vitamin D is found in some food, including eggs, milk and oily fish. Vitamin D helps the body absorb the calcium that bones and teeth need to stay healthy. Vitamin D deficiency has been linked to softening of the bones called osteomalacia, the adult version of rickets in children. Most of the vitamin D we need comes from regular exposure to sunlight. Most people know that too much sun can be bad for the skin, but too little is bad for the bones. Depending on skin type, the NHS recommends around 10 minutes in the sun twice a day without sunscreen during the summer. That should help the body store enough vitamin D to use all year round. Some people won’t be able to get enough sun, perhaps because they have to stay indoors for medical reasons, or cover up for cultural reasons. The Department of Health recommends that some adults take a 10 microgram (mcg) vitamin D supplement every day. Seek medical advice if you have concerns. Vitamin D supplements taken with calcium have also been shown to help to reduce the risk of hip fractures in older people. Doctors can check whether a person is short of vitamin D using a blood test. This may be done as part of overall checks to assess a person's risk of breaking bones if they have a fall. Up to a quarter of the UK population has low levels of vitamin D in their blood.

Studija naučnika s University of California iz San Diega pokazala je da kod žena sa potvrđenom visokom razinom vitamina D u organizmu, postoji i do 50% manji rizik obolijevanja od raka dojke. Čak je i blago povišena razina vitamina D bila povezana s 10%-tnim smanjenjem rizika za pojavu bolesti, utvrđeno je u istraživanju u kojem je sudjelovalo više od 120000 ispitanica. Vitamin D se u organizmu proizvodi nakon izloženosti sunčevoj svjetlosti, a prisutan je i u ribi, posebno onim vrstama koje obiluju uljem. Viši unos vitamina D se posebno preporučuje starijim osobama. Naučnici upozoravaju kako pretjerana izloženost suncu može imati negativan utjecaj na zdravlje te dodaju kako previsoka razina vitamina D u organizmu može dovesti do opasnog povećanja količine kalcija. Dakle pazite da ne pretjerujete, te održavajte optimalnu razinu vitamina D u organizmu.
