Vitamin D – The foundation of a healthy life

Many people are diagnosed with vitamin D deficiency, ranging from adolescents to seniors. That is why it is important to know what Vitamin D is.

Vitamin D deficiency has become a common symptom in recent times. In fact, like a contagious disease, this deficiency is spreading everywhere. Nearly half the world is plagued by vitamin D deficiency. Many people are diagnosed with vitamin D deficiency, ranging from adolescents to seniors. That is why it is important to know what Vitamin D is.

The word ‘vitamin’ in English is derived from the two words ‘vital’ and ‘amino’. Vitamin means a very important amino acid. A chemical called vitamin is essential for the smooth functioning of the body. Vitamin D was discovered by German chemist Adolf Windous in 1920. He was awarded the Nobel Prize in 1928 for this important discovery. It is the only vitamin that is formed by the combined coordination of sunlight, kidneys and liver. It helps in the concentration of calcium in the blood. Vitamin D is important for many functions in the body. It also plays an important role in bone development. Vitamins are classified into two groups, fat-soluble and water-soluble.

There is less blood in the body; Eating these six things is beneficial. Does sunlight directly give vitamin D? Sunlight does not directly give you vitamin D. Sunlight plays a role in the formation of this vitamin. The active form of vitamin D, which the body needs, is called ‘calcitriol’ or ‘activated vitamin D3’. It is not just vitamin D. The journey of production of this vitamin begins under the skin and ends in the kidneys. Simply put, this is a three-stage journey. In the first stage, vitamin D is produced naturally in the skin. It is made from the ubiquitous form of cholesterol ‘7-Dihydrocholesterol’. When you are in the sun, the sun produces two types of ultraviolet rays, UVA and UVB. Of these, UVB converts cholesterol under the skin to a vitamin called ‘cholecalciferol’ or ‘D3’. Then the next journey of vitamin D3 begins. It reaches the liver. The liver in our body breaks down through a chemical reaction with water. This means that Vitamin D absorbs extra molecules of oxygen and hydrogen to make Vitamin D – Hydroxyvitamin D or 25 (OH) D. After that, it begins its third and final phase of the 25 (OH) D kidney. In the kidney it receives the final pair of oxygen and hydrogen molecules. It makes 1.25 dehydroxyvitamin D. 1.25 (OH) D of Vitamin D is simply called Calcitriol or Activated Vitamin D.

Bone growth and vitamin Vitamin D is one of the most important factors in maintaining bone growth and calcium levels in the body. The body needs vitamin D to absorb calcium from its diet. Calcium forms the main foundation for bones. In contrast, vitamin D deficiency leads to inadequate absorption of calcium from the diet. In this condition the body has to use the calcium stored in the bones. This not only weakens the existing bones but also prevents the formation of new ones. Deficiency and Depression Not much is known about the role of vitamin D in depression. This vitamin regulates the genes that boost the immune system and release neurotransmitters in the brain. Neurotransmitters exchange messages in the brain. They affect brain function as well as mood and its development. Researchers have found that vitamin D receptors in a small number of cells in the same area of the brain are associated with depression. A number of studies have shed light on the link between depression and low levels of vitamin D in humans. Why the shortage? One of the major causes of vitamin D deficiency is insufficient time in the sun. The current lifestyle is hectic. It does not have much exposure to sunlight due to closed room activities like office work. Another reason is that the liver or kidneys cannot convert vitamin D into its active form in the body or the body is not able to absorb enough vitamin D from food. Inadequate intake of Vitamin D is also the third reason for its deficiency. In addition, vitamin D deficiency is caused by the use of certain drugs, age, underactive parathyroid glands, etc. Vitamins and Diet An adult needs 600 units of vitamin D daily. Considering the diet alone, there are very few vitamin D alternatives in vegetarianism. Vitamin D is not found in almost any vegetable. Mushrooms are a rich source of vitamin D, which is available in vegetarian diets. These foods flood the need for vitamins Nutrients that are not naturally added are added to the solution. Plants with vitamin D do not contain D3, but ergocalciferol or D2. So, for vegetarians, eating foods rich in vitamin D is the only option left. Vitamin D in animal products is known as D3. It is more capable of raising vitamin D levels in the blood. Fish is one of the best sources of non-vegetarian food. A one-time fish diet can meet the need for vitamin D throughout the day. In addition to fish, a large egg can provide 9% of the daily requirement of vitamin D. Vitamin D needs can also be met by injections and pills. Doctors can recommend them as needed. Ten to thirty minutes of sunlight every morning is recommended to meet the body’s need for vitamin D. Excessive sunlight or intense sunlight at other times of the day can cause skin or other problems. This condition is called ‘hypervitaminosis D’. This condition is not usually caused by sunlight or natural foods. This is a rare but serious condition. Taking too much vitamin D can lead to diarrhea. This usually happens when it is taken in the form of drugs. It can invite bone loss and high blood pressure. In addition, if not treated in time, the kidneys are also damaged.
