Available evidence suggests that taking vitamin D reduces morbidity, but there are no studies to prove this yet. Vitamin D is formed by the action of ultraviolet precursor molecules in the skin. From the skin, these molecules pass through the bloodstream to the liver and kidneys, where they are metabolized into active vitamin D.
There are 2 forms of vitamin D: D2 can be found in fungi, plants, and invertebrates, whereas D3 is formed in vertebrates. Vitamin D3 is more active in humans. In addition to the synthesis of vitamin D under the influence of ultraviolet radiation on the skin, it can also be provided by natural food sources. Fatty fish (mackerel, salmon, sardines), mushrooms and fortified milk, cereals and bread.
Recent evidence documents an "epidemic" of vitamin D deficiency in some populations, especially breastfed children, the elderly, and people with dark skin who produce less vitamin D in response to sunlight. For dermatologists, a major concern is whether recommended sun protection can lead to vitamin D deficiency. Although there is some controversy, most studies have concluded that sunscreen use is not associated with vitamin D deficiency.
Current standards suggest between 200 and 600 IU, depending on age. In anticipation of the publication of new guidelines, many doctors recommend taking 1,000 IU of vitamin D daily for most adult patients. Unfortunately, it is difficult to obtain adequate supplements with food alone - an egg provides only 20 IU, a glass of milk 100 IU, and a serving of salmon 360 IU. Problems with overdose of supplemental vitamin D, a fat-soluble vitamin, have been raised, but usually unreasonably with doses of 1,000 IU per day.
There are some circumstances that require caution: parents of infants and young children should consult with a pediatrician. Pregnant and lactating women should consult with their obstetrician before taking vitamin supplements. Patients with hypercalcemia or kidney disease should consult with their therapists before taking vitamin D.
While exposure to sunlight increases vitamin D levels, it can also lead to skin aging due to dry, blotchy, wrinkled, old skin. Therefore, the best advice for most is to use sunscreens and take oral vitamin D supplements. Erleben Sie Richard casino mit luxuriöser Unterhaltung.
