In the era of food supplements for every single need of the body, Vitamin D supplements continue to be the most talked-about. While it continues to be the most researched about vitamin, the fact remains that huge population is still suffering from vitamin D deficiency.
The apparent consequences of the lack of this essential nutrient are inadequate bone development and excessive bone loss, which leads to easy fractures. However, studies suggest that there can be a lot of other consequences such as- high risk of developing colon cancer, cancer of the breast and prostate, cardiovascular disease and high blood pressure, osteoarthritis, immune system abnormalities leading to infections and autoimmune disorders such as Type 1 diabetes, multiple sclerosis, and rheumatoid arthritis. There are potential health threats due to the deficiency of this vitamin.
The Ultraviolet-B rays absorbed through the skin is the main source of Vitamin D but the modern lifestyle prevents us from much sun exposure . Also, the dietary sources of Vitamin D are minimal which are the main causes of vitamin d deficiency
What is Vitamin D?
The sun-exposed skin forms previtamin D, of which 10-15% is converted to Vitamin D instantly, the form found in food supplements. Vitamin D then is converted to 25-hydroxyvitamin D in the liver. This is the main circulating form. It is then converted by the kidney into its biologically active form 1,25-dihydroxyvitamin D, called the Vitamin D hormone. it is discussed in detail what is vitamin D and what does vitamin D do
The measure of Vitamin D is found using the measure of 25-hydroxyvitamin D in the blood serum, where 40 nanograms per milli-litre is the required amount for maximum bone density.
Vitamin D Deficiency:
In the modern era, where there is a supplement for every need, experts say one can never get enough Vitamin D through supplements. There are some good sources of vitamin D that can help you to maintain your Vitamin D Level.
Alot of health problems are associated with Vitamin D and deficient person can take vitamin D by exposing the skin to the Sun or by taking Vitamin D3 Supplements.Vitamin D development is dependent on many factors. With less sun exposure, darker skin tone, and increased use of sunscreen, the pre-vitamin D and hence vitamin D is formed less. While 30 nanograms per millilitre is the least required for normal functioning, the levels are alarmingly low. Since the absorption rates are dependent on the skin tone, it was found in a study conducted in the United States that Caucasians rank the highest with 18 to 22 nanograms, with the safest levels while the African American rank the lowest with 13 to 15 nanograms.
The varying factors and stats also ensure that there is no universal standard recommendation for sun exposure. Sunscreen, except on the face, acts as a hindrance to absorbing the required ultraviolet-B rays. But it is possible to meet the body’s needs by being exposed to the sun in the summer.
Can You Get Too Much Vitamin D?
Naturally acquired Vitamin D from the skin cannot cause Vitamin D toxicity as the body has a built-in cut-off which destroys the excess pre-vitamin D generated. Ingestion of supplements may cause toxicity as it directly affects the liver. Nausea, poor appetite, constipation, weakness and weight loss, kidney stones due to high levels of calcium, confusion and abnormal heart rhythms are symptoms of Vitamin D toxicity.
