The risk of children suffering from flu can be reduced by 50% if they take vitamin D, doctors in Japan have found. The finding has implications for flu epidemics since vitamin D, which is naturally produced by the human body when exposed to direct sunlight, has no significant side effects, costs little and can be several times more effective than anti-viral drugs or vaccines according to research in the American Journal of Clinical Nutrition.
Only one in ten children, aged six to 15 years, taking the sunshine vitamin in a clinical trial came down with flu compared with one in five given a dummy tablet. Mitsuyoshi Urashima, the Japanese doctor who led the trial, told The Times that vitamin D was more effective than vaccines in preventing flu. (more…)
One single dose of calcitriol, the metabolically active version of vitamin D, followed by ongoing vitamin D supplementation has been shown to prevent the progression of multiple sclerosis, according to new research.
Calcitriol (vitamin D3), is transformed in the liver and kidneys into 25- hydroxyvitamin D (25(OH)D), the non-active ‘storage’ form, and 1,25-dihydroxyvitamin D (1,25(OH)2D), the biologically active form that is tightly controlled by the body.
Several studies have reported that the D3 form of the vitamin is more potent that D2, with a study led by Robert Heaney, MD, from Creighton University in Nebraska reporting earlier last year that D3 was 87% more potent than D2 (Journal of Clinical Endocrinology & Metabolism, doi: 10.1210/jc.2010-2230).

Mentally and socially stimulating activities, long believed to stimulate the brain, have no major effect on preventing brain shrinkage, especially when compared to the oldest therapy in the world–exercise. According to a study published in the journal Neurology.New research out of the University of Maryland School of Public Health shows that exercise may improve cognitive function by increasing the efficiency of brain activity associated with memory.
Memory loss associated with Alzheimer’s disease is one of the greatest fears among older Americans. While some memory loss is normal and to be expected as we age, a diagnosis of mild cognitive impairment, or MCI, signals more substantial memory loss and a greater risk for Alzheimer’s. (more…)
The idea that sunscreen prevents cancer is a falsity promoted by a profit-seeking tag-team effort between the cancer industry and the sunscreen industry. How convenient an oversight by these demonizers of the sun that people closest to the equator have the lowest incidence of skin cancer, but you’ll never hear that message on your local news. Instead, as the summer approaches the media bombards us daily with myths that blocking the sun’s rays from reaching our skin will somehow protect us from the one thing it actually prevents–cancer.
Blocking the sun’s rays from reaching our skin dramatically influences our optimal vitamin D levels, leading to higher mortality, critical illness and mental health disorders. Ironically, sunscreen itself causes cancer.

(Nov. 7, 2006)–What if a pill could lower your risk of cancer by as much as 70%? Vitamin D may be that magic medicine. University of California San Diego researchers analyzed national cancer deaths between 1950 and 1969 and again between 1970 and 1994–when people began staying out of the sun and wearing more sunscreen. (Our bodies require sunlight to make vitamin D.) Their comparison suggests that getting enough D could drive down mortality rates of 16 types of cancer–including breast and ovarian–by anywhere from 2 to 70%.
“Hundreds of lab studies show that vitamin D can stop cancer cells from proliferating and promote the death of tumor cells,” says lead author William B. Grant, PhD. Experts now recommend that people get 1,000 IU of vitamin D a day in summer, and as much as 2,000 IU in winter when the sun is much weaker. Getting that amount from your diet is tough. Your best bet is to take 1,500 IU daily in supplement form.

(NaturalHealth365) Low vitamin D levels can be the most damaging influence on our genetic health, according to professor George Ebers, Action Medical Research professor of Clinical Neurology and one of the senior authors of published scientific research.
What are the capabilities of vitamin D?
Researchers, at the University of Oxford, have shown the extent in which vitamin D interacts with our DNA. The researchers found 2,776 binding sites from the vitamin D receptor along the length of the genome. These are the ones unusually concentrated near a number of genes associated with autoimmune conditions such as MS, Crohn’s disease, systemic lupus, rheumatoid arthritis and cancers such as, lymphocytic leukemia and colorectal cancer.

A team of academic researchers has pinpointed how vitamin D3 and omega-3 fatty acids may enhance the immune system’s ability to clear the brain of amyloid plaques, one of the hallmarks of Alzheimer’s disease.
In a small pilot study published in the Feb. 5 issue of the Journal of Alzheimer’s Disease, the scientists identified key genes and signaling networks regulated by vitamin D3 and the omega-3 fatty acid DHA (docosahexaenoic acid) that may help control inflammation and improve plaque clearance.
