Vitamin D is commonly known as the Sunshine vitamin. It is prepared by the liver cells from cholesterol.
Vitamin D is actually a hormone, since the intermediate products (7 dehydrocholesterol) of its precursor are activated under the skin, in the UV radiation received from the sun.
Table of contents
Lack of vitamin D can lead to potential side effects in the body, which can lead to abnormal regulation of metabolism inside the body.
Vitamin D is a fat soluble vitamin that is absorbed only in the presence of sunlight. It is responsible for the strength of your muscles, bones and teeth.
Vitamin D is known as one of the main vitamins that are necessary for the proper functioning of the body. It helps in the defense mechanism and boosts immunity.
Very few natural sources of vitamin D are present. Some sources of vitamin D fatty fish like salmon, tuna, shrimp and mackerel.
It is also found in fish oil oils, which contain a good amount of vitamin D, and traces of vitamin D are visible in beef liver, cheese, and egg yolk. Less exposure to sunlight or indoor exposure may result in Vitamin D deficiency,
Sunlight helps in the proper absorption and activation of vitamin D intake, but most of us do not think about it.
Lack of nutrition or lack of adequate food intake can cause vitamin D deficiency. The presence of excessive melanin in the skin can block the absorption of vitamin D, which leads to a vitamin deficiency
Common symptoms of vitamin D deficiency:
1. Often the sick fall:
Vitamin D helps in the fight against harmful pathogens and bacteria that are trying to invade your system. Vitamin D is responsible for triggering the immune system, and thus its presence acts as a protective shield.
If you often become ill, especially from respiratory diseases, it is very likely that you suffer from a deficiency of vitamin D.
Smoking aggravates the problem of respiratory diseases such as COPD and Vitamin D deficiency was found in a smoking group of people.
2. Lethargy or physical fatigue:
Being tired can easily germinate from vitamin D deficiency. It has been shown that a lack of vitamin D causes tiredness and fatigue in people, even after a good night’s sleep.
These symptoms can be a warning signal for you if you also experience the same signs.
3. Fragile or weak bones:
The presence of fragile bones is an indication that you are deficient in vitamin D. Bone growth is complemented by sources of vitamin D, and its deficiency leads to thinning of the bones or loss of bone.
Vitamin D promotes bone growth and development. Studies have shown that "a lack of vitamin D, followed by calcium, leads to poor skeletal health," as completed by an experiment.
4. Bone loss:
Bone loss is caused by decreased levels of vitamin D and calcium. Calcium reabsorption is inhibited by PTH (parathormon) if your blood level does not contain enough calcium, which is maintained by vitamin D.
This predisposes to health conditions such as osteomalacia (weakening of the bones), osteopenia (decrease in bone density) and osteoarthritis.
Thus, you have an increased risk of fracture when you get older, because your bones are subject to wear due to lack of vitamin D,
5. Mood disorders:
A mood displacement may unreasonably Vitamin D deficiencyVitamin D deficiency causes anxiety and depression among older people.
Vitamin D Functions
- Vitamin D functions with proper absorption of calcium and phosphorus, which are vital for body functions. It promotes bone growth and helps strengthen bones.
- It helps in greater absorption of calcium and phosphorus from the gastrointestinal tract. It also facilitates the mechanism of re-absorption of these minerals in the kidneys. Vitamin D also promotes the movement of calcium from the bones into the circulating blood.
- Vitamin D is needed to facilitate the deposition of calcium in the bone. Therefore, he is responsible for stronger bones and teeth.
- It blocks the secretion of parathyroid hormone, which causes the re-absorption of calcium from the bones. The kidneys stimulate the conversion of 25-hydroxy-vitamins D3 to the active form of 1,25-dihydroxy-vitamin D3. Vitamin D3 is necessary for calcium to enter the bone.
- When there is less calcium in the blood, your parathyroid glands begin to release PTH in the bloodstream, which is trying to remove calcium from the bones.
- If there is lack of vitamin D in body, here the activity here does not stop, and therefore the whole regulation of calcium intake is violated. This leads to thinning of the bones, making them porous and brittle.
- Vitamin D helps reduce inflammation
- Having enough vitamin D in your body can prevent the risk of cancer.
Why is it important to use vitamin D?
Vitamin D is very important because it is one of the most essential nutrients your body needs. Although it is required in small quantities, it plays a significant role in your growth and maintaining healthy muscles and bones and the immune system.
Vitamin D causes a disease more familiar in the old days, known as rickets. In the Rickets, bones cannot use the calcification process, which results in slower growth.
When a child develops, the bones begin to bend, as the bones are weak and improperly shaped to carry it. own weight due to Vitamin D deficiencyThis creates difficulty in walking and other weight-bearing exercises. In vitamin D deficiency, calcium-binding protein production slows down in the epithelial cells lining the intestine.
This leads to the fact that the movement of calcium is not absorbed, and, therefore, the body can not use the presence of calcium. Vitamin D can be obtained from cholesterol, which acts as a precursor.
Cholesterol breaks down into a 7-cholesterol product, which is then further converted into vitamin D3 or cholecalciferol. Cholecalciferol or vitamin D3 additionally modify the liver to 25-hydroxyvitamin D3.
Ramifications associated with vitamin D deficiency
- In case of malfunction of the liver, such as non-alcoholic fatty liver disease, Vitamin D deficiency found that there is increased liver inflammation. NAFLD is a condition in which excessive fat accumulates in the liver caused by alcohol abuse. Clinical studies have shown the role of vitamin D in the regulation of liver inflammation and fibrogenesis, thereby increasing liver function to insulin.
- 25-hydroxy Vitamin D3 is inactive during formation. It is activated only when the kidneys chemically change this 25-hydroxy Vit D3 to the active form.
- When the kidneys are not functioning normally, vitamin D3 cannot be used in your body, since activation of vitamin D3 does not occur. People with CKD or chronic kidney disease often experience Vitamin D deficiency,
Can vitamin B12 deficiency be damaging?
From the above discussion it is clear that vitamin D is necessary for the maintenance and proper functioning of the human body.
