Vitamin D is not really a vitamin in the traditional sense, because we are able to form it through the skin, once our skin is exposed to UV-B rays from the sun.The formation occurs in the skin from cholesterol. The suns rays have to be strong and the skin has to be directly exposed in order for our bodies to form enough natural vitamin D3 - also referred to as the sunshine vitamin. Deficiency is therefore particularly common in countries north of the equator.
Vitamin D contributes to the maintenance of normal bones and teeth, normal blood calcium levels and to the maintenance of normal muscle function. Vitamin D contributes to normal absorption/utilization of calcium and phosphorus. Vitamin D contributes to the normal function of the immune system. Vitamin D has a role in the process of cell division.
Vitamin D is needed for normal growth and development of bone in children and contributes to the normal function of the immune system.
What is Vitamin D?
Vitamin D is important for the body as it promotes the body's absorption of calcium and phosphate from the intestine as well as the deposition of minerals in bones and teeth. Therefore, to ensure the necessary uptake of calcium, vitamin D is a necessity for bones and is important in the prevention of osteoporosis (osteoporosis) as well as English sufferers. Due to the properties of the vitamin, vitamin D is especially important for infants and during pregnancy as it is essential for the baby's bone development, teeth and the mother's bones. Vitamin D is found in many different forms and so far 37 active substances have been found, each of which is different in their chemical structure. The greatest importance for the human body has D2 (ergocalciferol) and D3 (cholecalciferol), of which D3 is the most active form. Vitamin D is a fat-soluble vitamin, which means that the body cannot absorb vitamin D without a fat.
Where does Vitamin D come from?
Vitamin D is also known as the sunshine vitamin as the sun is one of the main sources of vitamin D. Sunlight consists of light with different wavelengths, of which the sun's UVB and UVA radiation are of most relevance to humans.
However, vitamin D from sunlight is only formed when the sun is high enough in the sky, otherwise UVB cannot penetrate the atmosphere. Thus, in Scandinavia, it is only in high summer that enough vitamin D3 is formed in the skin via sunlight, and when covered, used with sunscreen or dark skin (higher pigmented skin), the uptake of vitamin D3 is inhibited, thereby increasing need for vitamin D supplementation.
In addition, vitamin D is found in foods such as fatty saline fish, fish liver oil, cheese and other high fat dairy products, as well as egg yolks, avocados and vegetable oils. However, the amount of vitamin D consumed through the diet is insufficient to meet the body's needs.
What happens in the absence of Vitamin D?
The National Board of Health already recommends vitamin D supplementation for the elderly over 70 years, pregnant women and children especially children under 2 years, as well as people who do not get sun, and people with darker skin.
Vitamin D is essential for the body to absorb calcium and phosphate from the gut. When the body has too little calcium in the blood, a hormone from the parathyroid gland releases calcium from the bones. The consequence of the bones not being replenished with lime is that the bones will eventually become soft and deformed or bone fractures may occur. This occurs by severe deficiency of vitamin D and is called osteomalacia or English sufferers.
