    October 25, 2016 A simple Google search for "what does vitamin D do?" highlights the widely used dietary supplement's role in regulating calcium absorption and promoting bone growth. But now it appears that vitamin D has much wider effects—at least in the nematode worm, C. elegans. Research at the Buck Institute shows that vitamin D works through genes known to influence longevity and impacts processes associated with many human age-related diseases. The study, published in Cell Reports, may explain why vitamin D deficiency has been linked to breast, colon and prostate cancer, as well as obesity, heart disease and depression....

    MONDAY, April 4, 2016 -- Regular doses of vitamin D3 may improve heart function in heart failure patients, a new British study suggests. "These findings could make a significant difference to the care of heart failure patients," said study leader Dr. Klaus Witte, from the University of Leeds School of Medicine. "It is the first evidence that vitamin D3 can improve heart function of people with heart muscle weakness -- known as heart failure."
  • New Sunscreen Protects Against Skin Cancer, Allows Body To Produce Vitamin D

    Many people are getting the message loud and clear. That sunscreen helps protect you against skin cancer. But some experts say all that sunscreen is creating another problem. “That is the major cause for the vitamin D epidemic worldwide,” says Dr. Michael F. Holick, an endocrinologist at the BU School of Medicine. “Sunscreen absorbs ultraviolet light and ultraviolet light makes vitamin D in your skin, and if you put a sunscreen on with an SPF of 30 and it absorbs about 97-98% of the UV light, it will reduce the ability to make vitamin D in your skin by 97-98%,”...

    Samuel Blackstone, Details Magazine November 8, 2015Daylight savings time is here, whether you like it or not. That means more cold weather, less warm sun, and for some people, vitamin D deficiencies, which, like any vitamin deficiency, can cause a host of health problems. This week, though, researchers completed a preliminary study on vitamin D and found that if you do happen to get enough of this essential vitamin, it not only reduces the risk of heart disease, but also helps you exercise more strenuously, while simultaneously exhibiting lower signs of exertion. In layman's terms, vitamin D helps you exercise...

    Most seniors may suffer from some degree of vitamin D deficiency, according to a study from researchers at University of California at Davis and Rutgers University. For the study the researchers surveyed 400 men and women with an average age of 76 in either good health or with mild cognitive impairment. They found that nearly all of the participants showed low levels of vitamin D with 26 percent displaying a deficiency and 35 percent show what they classified as insufficiency. "This work, and that of others, suggests that there is enough evidence to recommend that people in their 60s and...

    Vitamin D can slow down or even reverse the initial prostate cancer or tumours without the requirement for surgery or radiation, says new research. While the researchers are not sure at this stage about the connection, they said vitamin D can at least slow down the multiplying nature of the tumour, which is crucial in initial stage prostate cancer. In many cases when the biopsy is taken, it requires 60 days for the inflammation from the biopsy to subside for an operation and during this supplements of vitamin D would be helpful, while under active surveillance, said researchers. “We do...

  • Vitamin D prevents diabetes and clogged arteries in mice

    03/19/2015 7:27:28 PM PDT · by ConservativeMind · 26 replies
    In recent years, a deficiency of vitamin D has been linked to type 2 diabetes and heart disease, two illnesses that commonly occur together and are the most common cause of illness and death in Western countries. Both disorders are rooted in chronic inflammation, which leads to insulin resistance and the buildup of artery-clogging plaque. Now, new research in mice at Washington University School of Medicine in St. Louis suggests vitamin D plays a major role in preventing the inflammation that leads to type 2 diabetes and atherosclerosis. Further, the way key immune cells behave without adequate vitamin D may...

    Genetics will determine whether a person infected with Ebola dies, scientists claimed today. A new study has found DNA could be the key to tracking the deadly effects of the virus which has ravaged West Africa. The World Health Organisation revealed nearly 5,000 people have died from the disease, which has devastated Guinea, Liberia and Sierra Leone. A team of scientists at Washington University believe their study has identified genetic factors behind the mild-to-deadly range of reactions to the virus.

  • Scientists Blow The Lid on Cancer & Sunscreen Myth

    According to a June 2014 article featured in The Independent (UK), a major study conducted by researchers at the Karolinska Institute in Sweden found that women who avoid sunbathing during the summer are twice as likely to die as those who sunbathe every day. The epidemiological study followed 30,000 women for over 20 years and “showed that mortality was about double in women who avoided sun exposure compared to the highest exposure group.” Researchers concluded that the conventional dogma, which advises avoiding the sun at all costs and slathering on sunscreen to minimize sun exposure, is doing more harm than...

    Healthy people taking vitamin D supplements are unlikely to see any significant impact when it comes to preventing broken bones or cardiovascular conditions, claims new research appearing in the latest edition of The Lancet Diabetes & Endocrinology. According to the AFP news agency, the study authors reviewed more than 40 previous trials in order to determine whether or not use of these vitamin supplements achieved a benchmark of reducing the risk of heart attacks, strokes, cancer or bone fractures by at least 15 percent. “Previous research had seen a strong link between vitamin D deficiency and poor health in these...

    In a multiethnic group of adults, low serum 25-hydroxyvitamin D concentration was associated with increased risk of coronary heart disease events among white or Chinese participants but not among black or Hispanic participants, results that suggest that the risks and benefits of vitamin D supplementation should be evaluated carefully across race and ethnicity, according to a study in the July 10 issue of JAMA. "Low circulating concentrations of 25-hydroxyvitamin D (25[OH]D) have been consistently associated with increased risk of clinical and subclinical coronary heart disease (CHD). Whether this relationship is causal and modifiable with vitamin D supplementation has not yet...
