The role of Vitamin D in preserving health

Vitamin D is part of a group of fat-soluble vitamins which can be obtained from a few foods, sunlight and supplements. The main role of Vitamin D is to assist in the metabolism of Calcium and Phosphorus and also in mineralization of bones. Till now, different forms of Vitamin D have been discovered, namely Vitamin D1, D2, D3, D4 and D5 respectively.

Vitamin D Deficiency – Reduced dietary intake or inadequate exposure to sunlight can lead to a deficiency of Vitamin D in the human body. Some studies have defined deficiency as a serum 25-hydroxyvitamin D level of less than 20 ng per mL (50 nmol per L), and insufficiency is defined as a serum 25-hydroxyvitamin D level of 20 to 30 ng per mL (50 to 75 nmol per L). In case of insufficient Vitamin D levels, 25 hydroxy- cholecalciferol was brought to the kidney and thus the kidneys cannot respond naturally and they fail to connect with blood calcium. The levels of calcium phosphate crystals begin getting low and hence form less soft tissue in the body. Less calcium from the circulation also creates the bone releasing all available calcium, for normality of blood calcium level. The bones, as a result, turn soft and bendable. Calcium in the bone activates the action of the osteoclasts and works as a synthesizer to the bone as well. But Vitamin D deficiency can cause dematerialization the bone. Some significant symptoms are bone pain & soft bones, frequent bone fractures, bone deformities or growth retardation in children.

The importance of Vitamin D during pregnancy

Vitamin D deficiency and insufficiency are common across the globe. Large epidemiological studies reveal the high prevalence of vitamin D in women, including antenatal and lactating mothers.

Vitamin D requirements are probably greater in pregnancy, as evidenced by physiologically higher 1,25-dehydroxy vitamin D levels seen in the second and third trimesters. While 1,25(OH) 2D levels do not correlate directly with 25 hydroxyvitamin D concentrations, the physiological rise in the active metabolite, the enhanced intestinal calcium absorption, and enhanced fetal requirement of calcium (250 mg/day in the third trimester) all point to the importance of vitamin D biology in pregnancy

The following people are more prone to Vitamin-D deficiency :

Vitamin D and its importance

What are the most important things that we need to know about Vitamin D?

Vitamin D is one of the most important vitamins that our bodies need in order to function in a healthy state. It is both a nutrient that we consume and a hormone that our bodies produce. It is colloquially referred to as the “Sunshine Vitamin” since our bodies naturally produce it after exposure to sunlight. Other sources of Vitamin D include foods such as dairy products, breakfast cereals, and fatty fish such as Salmon and Tuna.

What role does it play? What are its most important functions?

Vitamin D was initially considered to be responsible for maintaining the health and functionality of the muscles, bones and joints by facilitating the absorption and retention of calcium and phosphorus. However, further research over the last decade has shown that Vitamin D also plays a key role in developing a strong immune system, maintaining organ functionality and alleviating chronic conditions such as diabetes and asthma. Furthermore, a lack of adequate Vitamin D can also accelerate pre-existing mental health conditions such as dementia and schizophrenia, in the elderly.

All You Need To Know About The Sunshine Vitamin

We all know that Vitamin D is one of the most essential vitamins required for our body. The first thing that comes to people’s minds when they hear Vitamin D is that we get it from sunlight and it keeps our bones strong. These are true, but there is a lot more to know about the ‘Sunshine Vitamin’. Common misconceptions and negligence has left people with a huge risk of being Vitamin D insufficient.

Vitamin D is an important factor is building muscles and bones, and helping the human heart, brain and lungs function well. Vitamin D is unique in its characteristics because it is the only vitamin that the human body can make on its own. Unlike other vitamins which we get through various sources like food, the body makes its own Vitamin D when exposed to sunlight. Although, there are other means by which you can get Vitamin D like food and supplements. (more…)
