It used to be that we thought vitamin D just helped strengthen bones by improving the body’s ability to absorb and use calcium, but recent research has shown that vitamin D also affects the immune system, muscles, blood pressure and the heart.
Most dairy products are enriched with vitamin D, so choose low-fat dairy products as part of your diet in addition to your daily supplement. A schematic representation of the major causes of vitamin D deficiency and potential health consequences. Described by the New York Times as “the most talked-about and written-about supplement of the decade,” Vitamin D has recently been shown to play crucial roles in brain, heart, immune system and bone health [1].
While the health implications of hypovitaminosis D are still not completely understood, studies have indicated that normal vitamin D levels are required for healthy function of almost every tissue in the body [2]. While the most straightforward interventions to combat hypovitaminosis D would be to ensure adequate sunlight exposure and a healthy diet that includes natural sources of vitamin D (such as fatty fish), a slew of cultural and socioeconomic barriers constrain the efficacy of such approaches.  Dr. Like us on Facebook!SubscribeEnter your email address below to receive updates each time we publish new content. Vitamin D is an essential nutrient that your body synthesizes naturally when your skin absorbs sunlight. Excess Urination Too much vitamin D intake raises the calcium level in the blood, which forces your kidneys to overwork to get rid of the excess calcium from the body. Digestive Problem Overuse of vitamin D supplement causes nausea, vomiting, loss of appetite and diarrhea or constipation. Vitamin D deficiency has also been linked to the development of cancer, diabetes, fibromyalgia, high cholesterol and multiple sclerosis.
Like sunscreen, darker skin, which has higher amounts of pigment (melanin), blocks the important light wavelengths from getting to the skin to make vitamin D. Philippe Autier and Sara Gandini from the International Agency for Research on Cancer and the European Institute of Oncology, respectively, found that people who took a vitamin D supplement actually live longer. Both the causes (risk factors) and consequences of hypovitaminosis D tend to be magnified in the developing world. As a more complete picture of vitamin D’s importance has begun to emerge, so too have the tragic consequences of vitamin D deficiency in the developing world.

Hussein Saadi of UAEA University identifies “individuals with low sunlight exposure,” as the most at risk group for hypovitaminosis D3. While your kidneys filter the blood, the excess calcium deposits in the kidneys and over time form stones. Excessive vitamin D leaches calcium from your bones, which weakens the bones and triggers bone pain.
High calcium level in the blood following excess vitamin D ingestion impairs the normal function of the digestive system, leading to digestion disorders. Unfortunately, outside play, outdoor jobs, and weekends in the park are less common these days. As our knowledge of vitamin D grows, so does our understanding of its importance in our bodies. Michael Hooten of the Mayo clinic also reported that in patients with chronic pain, individuals with vitamin D deficiency required significantly higher doses of narcotic pain medicine and required them longer than people who were not deficient in vitamin D. The average daily dose of vitamin D was 528 IU in the study, and people who took a vitamin D supplement lowered their risk of death, by any cause, by 7%. Try not to get more than 2000 IU of vitamin D each day from supplements and dietary sources. Does…Thirty Ways to Live a Healthier Life Looking for Ways to live a healthier life? With a wide range of dietary, cultural, ethnic, and environmental factors playing major roles in deficiency, hypovitaminosis D (vitamin D deficiency) is fast becoming a top global health priority.  It is imperative that policymakers and global health specialists devise new and more efficient delivery strategies to get this crucial supplement to the developing world. Although humans naturally generate vitamin D in the skin when exposed to sunlight, cultural factors constrain sun exposure and dietary sources of vitamin D are often minimal.
Yet despite ample sunshine year-round, developing countries bear the biggest burden of hypovitaminosis D, with shockingly high prevalence ranges between 30–90% [4].  In Asia and the Middle East in particular, homebound individuals, women who wear long robes and head coverings for religious reasons, and people with occupations that limit sun exposure, are unlikely to obtain adequate vitamin D from sunlight. More resources and international attention need to be channeled into providing supplements to those in the developing world. The risk of developing calcium stones in the kidneys is especially higher in people suffering from sarcoidosis, a type of inflammatory disease that affects multiple organs.

Most of our lives are spent indoors without the sun exposure that our skin needs to create vitamin D.
The most interesting part of the research is that the study was done in summer when sunlight is most abundant—a time when we don’t often worry about getting enough vitamin D. This research suggests that vitamin D has an effect on the relationship between nerves, muscles and pain. Malnutrition, dark skin (melanin pigment reduces the skin’s ability to produce vitamin D from sunlight) and lack of access to supplements only exacerbate deficiency [5]. Intervention strategies and policies must be revamped; otherwise, developing nations will continue to bear the unacceptable disease burden of vitamin D deficiency.
Recent studies have elucidated the role of vitamin D in a number of body processes. For people who have a higher risk of vitamin D deficiency because of insufficient exposure to sunlight, increased intake of vitamin D rich foods helps in meeting the body’s demand for this essential nutrient. Excess consumption of vitamin D supplement for a prolonged period causes calcium to leak from the muscles, which causes muscle pain.
Furthermore, sunscreen and glass block the important wavelengths of light that are used to create this crucial vitamin.
Unfortunately, the reason for this benefit is unclear at this time, but further research is ongoing.
Edward Giovannucci of the Harvard School of Public Health writes, “Throughout most of human evolution, when the vitamin D system was developing, the ‘natural’ level of 25-hydroxyvitamin D was probably around 50 nanograms per milliliter or higher.
However, there are a small number of dietary sources of vitamin D, which necessitates intake of vitamin D supplements. Regardless, this information is impressive and reminds us of how important vitamin D is for our overall health. Although vitamin D is considered safe when taken in recommended amounts, excess vitamin D intake for prolonged period can cause serious side effects.
