Together this keeps blood calcium and phosphate steady and supports bone health. It may also support muscle and immune function, although this needs more research.<\/p><\/div>\n   <div class=\"sp-faq-item\"><h3>Can I get enough vitamin D from sunshine alone?<\/h3><p>Skin makes vitamin D in sunlight, but how much depends on season, time of day, age and skin pigmentation, and sunscreen limits it. Because of the long-term risk of skin cancer, sun exposure is not recommended as a vitamin D source for anyone, including children. Our physicians can advise you on what suits you.<\/p><\/div>\n   <div class=\"sp-faq-item\"><h3>Which foods contain vitamin D?<\/h3><p>Fatty fish and cod liver oil contain vitamin D, and egg yolk contains less. Some cereals and other products have it added. Cod liver oil also holds a lot of vitamin A, and too much vitamin A can cause side effects such as liver damage and bone fractures, so speak to a physician before adding it.<\/p><\/div>\n   <div class=\"sp-faq-item\"><h3>Can my vitamin D be low even if I feel fine?<\/h3><p>Yes. A level that is lower than normal often causes no visible signs or symptoms. It may still be linked with lower bone density and, in some people, a higher risk of falls and possibly fractures. A level check is the way to know.<\/p><\/div>\n   <div class=\"sp-faq-item\"><h3>Who is more likely to have low vitamin D?<\/h3><p>Infants, children and older adults, people who avoid dairy products, and people with limited sun exposure, especially those with more pigmented skin. Conditions that affect absorption, such as celiac disease, Crohn's disease and cystic fibrosis, stomach or intestinal surgery such as gastric bypass, and chronic kidney or liver disease also raise the chance.<\/p><\/div>\n   <div class=\"sp-faq-item\"><h3>What can happen if vitamin D stays very low?<\/h3><p>Deficiency may lead to low blood calcium, low blood phosphate, and softening of the bones, called rickets in children and osteomalacia in adults. Your physician will explain what applies to you and decide on treatment.<\/p><\/div>\n  <\/div>\n <\/div>\n<\/section>\n\n<section class=\"sp-dark\" aria-labelledby=\"sp-end-h\">\n <div class=\"sp-wrap sp-closegrid\">\n  <div>\n   <p class=\"sp-k\">Talk to a physician<\/p>\n   <h2 id=\"sp-end-h\">Let us check where your vitamin D stands<\/h2>\n   <p class=\"sp-cta2\"><a class=\"sp-book-desktop\" href=\"\/book-appointment-desktop\/\">Book a Consultation<\/a><a class=\"sp-book-mobile\" href=\"\/book-appointment-resp\/\">Book a Consultation<\/a><\/p>\n   <p class=\"sp-disc\">This page is general information.
