Vitamin D can also be obtained through other sources, including fatty fish (such as tuna, mackerel, and salmon), foods fortified with vitamin D (such as dairy products, soy milk, and cereals), beef liver, cheese, and egg yolks. Of course, as a dermatologist I am not advocating for prolonged sun exposure, but small amounts can go a long way, as the skin produces vitamin D that can last at least twice as long the vitamin D you take in through foods or supplements. This is mostly due to vigilant sun protection, since sunscreen with SPF 30 reduces vitamin D production by 95%. Vitamin D deficiency is very common and on the rise. Your body produces vitamin D when the skin is exposed to sun, and it is estimated that most people need 1,000 to 1,500 hours of sun exposure throughout the spring, summer, and fall to obtain the necessary amount of vitamin D. How do I get the vitamin D I need?ĭon’t run out to the drug store to buy vitamin D pills just yet. A small study published earlier this month suggested that high-dose vitamin D could reduce redness and inflammation following sunburns, but the dose tested far exceeded the recommended daily dose of vitamin D.

Studies looking at the benefits of vitamin D on various conditions are ongoing. However, most of the effects of vitamin D have not been studied in controlled settings. Adequate vitamin D during pregnancy also appears to reduce the chances of having a low-birthweight baby. Vitamin D is likely beneficial for other parts of the body as well studies suggest an overall decrease in death in addition to reductions in blood pressure, respiratory illnesses, cancer, heart disease, and depression. Without sufficient vitamin D, bones become brittle (in children this is called rickets and in adults it is called osteomalacia) and break more easily. Vitamin D facilitates absorption of calcium and phosphate, which are needed for bone growth. My husband, of course, has no idea how much vitamin D he needs or why, and I suspect he is not alone.

Over the July 4th weekend, my non-physician husband with a history of skin cancer tried to justify not wearing sunscreen in order to get some vitamin D.
