Vitamin D plays an integral role in multiple systems in the human body, from its function in

The reduction of circulating PTH by blood calcium leads in turn to decrease in levels of circulating PTH and reduction action of 1-alpha hydroxylase in the kidney [11]. Deficiency of VD has been associated with many adverse health problems including muscle weakness, infectious diseases and mortality in the critically ill patients

From the electronic database searches, several articles were appropriate. The first, "Vitamin D deficiency and depression in adults: systematic review and meta-analysis", was designed to find a relationship between Vitamin D and depression (Anglin, Samaan, Walter, & McDonald, 2013). Although, limited by the lack of random control trials, the data was presented in a uniform and consistent manner (Anglin et al., 2013). The results were in line with their goal, finding that low Vitamin D levels did correlate with increased depression (Anglin et al., 2013). Second, Meehan, and Penckofer, provided their inductive, exploratory opinion of "The role of Vitamin D in the aging adult" (2014). Although, the study was short and depression symptoms were self-reported, it, nevertheless, showed a correlation between low levels of Vitamin D and depression symptoms (Meehan, & Penckofer, 2014). The third article, "Vitamin D supplementation to prevent

Boosting your immune system,Vitamin D helps your body regulate the absorption of your calcium and phosphorus.

Vitamin D plays a critical role in many normal bodily functions as well as fighting against a wide number of health barriers. In an article by Jacqueline Kanopa, studies revealed that exposure to ultraviolet rays play a huge part in Vitamin D production, as well as having preventative effects on a disorder known as rickets; which leads to weakened bones due to lack of Vitamin D. This study supports the belief that exposure to UV rays play a critical role in Vitamin D production, and can be beneficial to those prone to certain

As most people, you are your best medical care advocate. You must inquire early about your vitamin D levels almost every time you see your healthcare provider and get blood work done. If you show signs of lower vitamin D levels, you should make a plan with your doctor for ways to reach a recommended level. Some people can achieve a recommended level through diet or sun exposure, however, getting enough through food and sun exposure comes with its own risks. Those individuals who cannot achieve the recommended levels through diet or sun exposure can take supplements in a pill form. There is some information online about recommended daily intake levels, but levels will vary from each individual. Setting up a plan with your healthcare provider for how much vitamin D you need to take and continual monitoring is the best route. These is some adverse effects that involve the cardiovascular system and kidneys, therefore, I would highly recommend making a plan with your health care

Critical roles that Vitamin D plays include the regulation of blood calcium, bone homeostasis, bone metabolism, cell growth and division, and adaptive and innate immune responses. Vitamin D in the form 1,25(OH)2D becomes functional by binding to a nuclear VDR and retinoid X receptor to control gene transcription. Pathology is caused by the dysregulation of T cell responses. When T cells are activated in a long-lasting and problematic way, immune mediated diseases happen. A sub-group of the T cells known as the regulatory T cells, or suppressor T cells, plays an important role in modulating the immune system, sustaining tolerance to self-antigens, and stopping autoimmune disease. When there is a deficiency of regulatory T cells, immune mediated diseases occur. As such, regulation of T cell response is critical to the healthy functioning of the body, and to prevent chronic activation of the T cells (Cantorna et al.

Synthesis reveals that athletes in countries that experience less sunlight are more likely to have vitamin deficiency compared to other athletes living in other regions, specifically near the equator. This finding is based on the identified relationship between sunlight exposure and vitamin D absorption. Likewise, Ogan and Pritchett determined that athletes that are not frequently exposed to sunlight suffers from the same risk as seen by the reviewed literature of their study. These findings suggest that vitamin D supplementation should vary as athletes have different

Vitamin intake is a commonly overlooked necessity in basic nutritional health. What most people do not know is that certain vitamin deficiencies can cause many health risks and problems. Many people believe that are getting all the vitamins they need from their diet, however most of the time they are not. One of the most common vitamin deficiencies is the low intake of Vitamin D. There are some vitamins that are produced by the body such as vitamin K; however some of the most important vitamins are not produced by the body. Vitamin D is one of the vitamins that our body needs to function correctly that is not naturally produced by the body. Vitamin D can be consumed through

For decades, the "natural" health industry has spoken of vitamin supplements as being essential for a healthy and productive life. Consider some individual examples of food-based vitamins and their synthetic analogues. The authors of the published scientific research are affirmative about the usefulness of taking vitamin

However, due to the many technological advances that we have today, we are able to live in places where our skin pigmentation has no accord with the UV radiation of our current environment; this lack of harmony results in many mental and physical deficiencies, the most common of which is vitamin D

Starting in October, sun exposure drops significantly which depletes vitamin D levels. The levels are likely at their lowest near the end of December. Vitamin D is most popular for its role in keeping bones strong, however, a lesser known role of vitamin D is in the immune system. When vitamin D levels are low your risk of infection increases significantly!

Those who do not get enough exposure to the sun or people with darker skin are more likely than those with fair skin whose time in the open air makes them deficient in vitamin D. The use of sunscreen can also affect the synthesis of vitamin D .

The study also showed that Vitamin D deficiency decreased FEV1, especially during asthma exacerbations.4 Some weaknesses of this study may be that the surveyors compared the results obtained in their study to those studies that were done “in vivo”.4 The strengths of this study include the time span over which it took place as well as the amount of factors taken into account to retrieve the appropriate data necessary to make the conclusion that a deficiency of vitamin D is related to asthma exacerbations and poor lung function.

During the Industrial Revolution we see a drastic shift from an outside to inside workplace. People changed from a farming and factory job to a commercial and office job. As a result of the limited time spent outside due to the workplace there was an increase of Vitamin D deficiencies among the people. Yet, receiving a sufficient amount of Vitamin D is essential for the body since this vitamin does not only aid in strong bones, but many other crucial organs. This vitamin is important for all age groups, especially younger children since it is vital for brain development. But, it also benefits our respiratory system and a deficiency can cause respiratory distress, such as asthma. Vitamin D can not be absorbed through food, since it has to be

Katarzyna, Sherine, Garry, Derek, Stephen James, and Ian (2015), authors of the article “Antioxidants in cardiovascular therapy: Panacea or false hope?”, re-examined the roles played by antioxidants such as vitamins A, C, and E, folic acid and other B vitamins, polyphenols, mineral such as selenium, drugs such as N-Acetylcysteine (NAC) and allopurinol in regards to their therapeutic properties to combat various illnesses such as heart diseases, ischemic strokes, and peripheral arterial disease. Katarzyna et al. (2015) also explored the setbacks related to the antioxidants’ properties in the cardiovascular disease prevention and management as well as the myths and merits linked to this research topic. The researchers compared the data gathered
