What is vitamin D3?
Vitamin D3, also known as cholecalciferol, is in fact the hormone of the bite and not a real vitamin. The body is produced when the skin synthesizes sunlight after exposed to ultraviolet (UV) beams. In addition to solar radiation, there are other ways to get vitamin into the diet, through fortified foods or supplements. Sufficient vitamin D3 levels are necessary for optimum calcium absorption, helping to create strong bones and teeth. However, too many of this can be toxic and lack can also lead to problems such as osteoporosis and intersections.
The most common way to obtain vitamin D3 is direct exposure to sunlight. After contact with UV rays from the Sun, the skin of cholecalciferol produces, which is then transmitted to the liver, where it is converted into calcafediol. From there it is transported to the kidneys and converted into calcitriol, the most active form of vitamin D.
to synthesize the skin with vitamin D3, needs direct sunlight without sunscreen and ne through the window. However, the length of time spent in the sun should be limited due to the risk of skin cancer. For those who have fair skin, it is enough for about 20 minutes in the sun to create a sufficient amount of vitamin, but those with dark skin may need longer. The exposure to sunlight generally does not cause vitamin D toxicity, because after a certain time vitamin is produced at the same speed as degraded and destroyed.
Vitamin D3 can also be obtained through animal products and accessories. Some fish species such as catfish, salmon and tuna contain vitamin and fortified foods such as milk and cereals. This can also be found in Lanolin, which comes from sheep. In addition, vitamin supplements that usually come in a pill or liquid form can be used. Vitamin D3 is often preferred before vitamin D2, which symbols them plants because it is generally more effective and easier for the body.
body uses vitamin D3 to help with calcium and phosphorus absorption, which increases bone densityand supports strong bones and teeth. Vitamin also regulates the neuromuscular system and the immune system. It is generally recommended that adults receive at least 400 IU vitamin D daily, but not more than 2,000 IU, gain full benefits.
Too much vitamin D3 in the body can cause overdose while too little can lead to deficiency. Toxic levels that cause overdose can lead to kidney and heart problems. The deficiency increases the risk of osteoporosis, intersections and certain types of cancer.
