London (Parliament Politic Magazine) – A growing body of medical research is consistently suggesting various ways in which vitamin D can effectively protect against serious health conditions. Many of us possess a general understanding that vitamin D, also known as the “sunshine vitamin,” is linked to overall well-being. However, this understanding is often accompanied by a concern that in Britain’s frequently overcast weather.
Therefore, we may not receive an adequate amount of this essential nutrient. In recent years, medical research has shed light on the numerous ways in which vitamin D can safeguard against severe health conditions. Moreover, it has become increasingly apparent that vitamin D supplements can be just as beneficial as naturally synthesizing them from sunlight exposure.
The Role of Vitamin D Linked to Health Benefits
A groundbreaking study, recently published in the esteemed British Medical Journal, has shed light on the potential of vitamin D supplements. It helps in reducing the risk of heart attacks among individuals aged 60 and above. Furthermore, previous research has indicated that these supplements may also play a role in preventing dementia in older adults. Given these findings, one might wonder if vitamin D supplements should be a part of everyone’s daily routine.
Interestingly, the government recommends vitamin D as the only supplement that is broadly suitable for all adults, even during the autumn and winter months. However, the direct benefits of this supplement continue to be a subject of intense debate within the medical community. While many of us associate vitamin D with its role in promoting healthy teeth and bones. Recent years have seen it being linked to many other health benefits.
During the COVID-19 pandemic, there has been increased attention on the correlation between severe cases of the virus and low levels of vitamin D. Initial reports indicated that individuals with the most severe COVID-19 symptoms also exhibited deficiencies in vitamin D.
However, subsequent research has shed light on an alternative explanation. It is now believed that the disease itself may decrease the body’s vitamin D levels, rather than low vitamin D levels being a predictor of the severity of COVID-19 symptoms.
Why is Vitamin D Essential for our Health?
The association between vitamin D and teeth and bones stems from a discovery made just over a century ago. It was found that a deficiency in this vitamin could lead to a condition called rickets. It causes weak and deformed bones, particularly in children with bowed legs.
Dr. Milli Raizada, a GP and senior clinical lecturer in primary care at Lancaster University’s Medical School, explains more clearly. She states that vitamin D plays a crucial role in the absorption of calcium and phosphorus from the gut. This absorbed calcium then mineralizes and strengthens our bones. For a long time, this was believed to be the sole benefit of vitamin D.
However, Professor Martin Hewison, director of the Institute of Metabolism and Systems Research at the University of Birmingham, points out something more. Recent scientific advancements have expanded our understanding of this vital nutrient.
“Approximately 25 years ago, researchers made a groundbreaking discovery regarding the vitamin D receptor. They found that this receptor, responsible for transmitting the effects of vitamin D, exists in numerous tissues beyond the intestine. Surprisingly, it is present in cancer cells, muscles, and even the immune system, which is unrelated to its traditional role in preventing rickets.
What is Vitamin D Deficiency?
Vitamin D deficiency is a condition that can have different effects on children and adults. In children, it can lead to bowed legs and a condition called rickets. However, in adults, it is more commonly associated with symptoms like fatigue, bone pain, and muscle pain. Additionally, older individuals who lack vitamin D may be at a higher risk of experiencing falls, as pointed out by Dr. Raizada.
To determine your vitamin D levels, a test can be conducted by your general practitioner (GP). According to the guidelines provided by the National Institute for Health and Care Excellence (Nice), testing is only recommended if you have symptoms. This means you may not be tested unless you are experiencing these deficiency symptoms.
Dr. Raizada explains that individuals who are more susceptible to vitamin D deficiency include children and those over the age of 65. It also includes pregnant or breastfeeding women and individuals with conditions that hinder vitamin absorption or affect the kidney or liver.
