What is vitamin D?
Despite the name, vitamin D is considered a pro-hormone and not a vitamin.
Vitamins are nutrients that the body cannot create and must, therefore, be taken by our diet.
However, vitamin D can be synthesized by our body when sunlight hits our skin.
A sun-sensitive skin exposure for 5-10 minutes 2-3 times a week will allow most people to produce enough vitamin D, but vitamin D degrades fairly quickly, which means that the reserves mostly in the winter.
How does it work?
Vitamin D is necessary for the regulation of calcium and phosphorus minerals in the body. It also plays an important role in maintaining the proper bone structure.
Vitamin D is most effective element of multivitamins and we know.
multivitamins important for us. Exposure to the sun is a simple and reliable method for most people to get Vitamin D. Hands, face, arms and legs in the sunlight two or three times a week about a quarter of the time necessary to develop a pair of sunglasses, the skin will produce enough Vitamin D. The required exposure time varies depending on age, skin type, season, time of day, etc.
It’s amazing how much sunlight can restore adequate vitamin D levels. 49 days of solar irradiation can only compensate for 6 days of accidental exposure to the sun without sunscreen. Body fat acts as a kind of vitamin D accumulator. During sunlight, vitamin D is stored in fat and then released when sunlight disappears.
However, vitamin D deficiency is more common than expected. People, who do not have enough sun, especially people in Canada and the northern half of the United States. They are particularly vulnerable. Vitamin D deficiency also occurs in sunny climates, perhaps because people stay indoors, cover themselves or use sunscreen to reduce the risk of skin cancer.
Vitamin D Deficiency
Although the body can produce vitamin D, there are many reasons why a deficiency can occur. For example, the dark color of the skin and the use of sunscreen reduce the body’s ability to absorb the sun’s ultraviolet B (UVB) rays that are needed to produce vitamin D.
A sunscreen with sun protection factor (SPF) can reduce the body’s ability to synthesize vitamin 95 percent. To begin with the production of vitamin D, the skin must be exposed directly to sunlight, not covered by clothes.
People who live in northern latitudes or in highly polluted areas, who work at night, stay at home during the day or stay at home should try to consume more vitamin D from food sources if possible. Babies who are exclusively breastfed will need a vitamin D supplement, especially if they are dark skinned or have minimal exposure to the sun. The American Academy of Pediatrics recommends that all breastfed infants receive 400 IU per day of oral vitamin D supplements; Drops, especially for babies, are available.
Important sources of vitamin D
Sunlight is the most important source of vitamin D. Ultraviolet rays increases the rate of vitamin D production in the skin. Fifteen minutes of sun exposure a day is enough to meet your vitamin D needs. It is found in some foods such as mackerel, sardines, and salmon. Other good sources are butter, egg yolk, cod liver oil, boletus and sweet potatoes is Important for vitamin D. Enriched milk also contains a certain amount of vitamin D.
Osteomalacia is a disorder that occurs in the skeleton. The meaning of the word “osteomalacia” is “soft bones”. Minerals, calcium, phosphorus and collagen matrix, osteoclasts and osteoblasts are the four main components of bone. Osteoclasts are cells that destroy bone, and osteoblasts are bone-forming cells. The collagen fibers in the matrix are covered with minerals. The strength of a bone depends on the rich mineral coating of the collagen matrix. The mineral coating, when present in large quantities, forms a strong bone. Osteoclasts remove old bone and osteoblasts form the new collagen matrix. Osteomalacia occurs when the process of mineral formation is not performed properly. In this disease, new bones are formed without mineral coating, which leads to softening of the bones. These types of bones can easily crack or bend. Osteomalacia is treated with an oral dose of vitamin D and direct exposure to the sun. An alternative to ultraviolet absorption is the use of UV lamps.
