High-Dose Vitamin D May Not Curb Kids' Colds

Posted 9 days ago by Drugs.com

TUESDAY, July 18, 2017 – When it comes to vitamin supplements, more is not always better, according to a new study that found even high doses of vitamin D don't protect children from colds in the winter. "We may have just busted a myth," said study leader Dr. Jonathon Maguire. "Our findings do not support the routine use of high-dose vitamin D supplementation for the prevention of wintertime upper respiratory tract infections among healthy children," added Maguire. He is a pediatrician at St. Michael's Hospital in Toronto. Vitamin D is often called the "sunshine" vitamin, because human skin manufactures the nutrient upon contact with sunlight. It's also found in certain foods, such as fatty fish. But many people now take a daily vitamin D supplement, as well. For the past 30 years, it's been thought that vitamin D can help prevent or reduce the severity of colds and other respiratory ... Read more

Could Your Office Job Rob You of Vitamin D?

Posted 22 Jun 2017 by Drugs.com

THURSDAY, June 22, 2017 – Spending your days cooped up inside an office might mean you're not getting enough vital vitamin D – know as the "sunshine vitamin," researchers report. Canadian researchers found that vitamin D deficiency levels differ by occupation, with people who are closeted indoors faring worse than others. "We know that vitamin D deficiency and insufficiency is prevalent in the population at large. We can now say that occupation is a factor that is important in determining if someone may be vitamin D-deficient or not," said lead researcher Dr. Sebastian Straube. He's an associate professor of preventive medicine at the University of Alberta in Edmonton. Vitamin D is found naturally in a few foods, and often added to milk and other products. Skin exposure to sunlight also produces vitamin D, which is why it's called the sunshine vitamin. In the new research, Straube and ... Read more

Many Americans May Be Taking Too Much Vitamin D

Posted 20 Jun 2017 by Drugs.com

TUESDAY, June 20, 2017 – When it comes to vitamin D supplements, it's possible that Americans may be getting too much of a good thing, new research suggests. In 2014, just over 3 percent of U.S. adults took more than 4,000 international units (IUs) of the vitamin daily, exceeding the upper limits of what is considered safe, the researchers said. In 2007-2008, only 0.2 percent did that. For perspective, the recommended daily amount of vitamin D is only 600 IUs for adults aged 70 and younger. For those over 70, the recommendation is 800 IUs a day. "More may not always be better with vitamin D," said study author Mary Rooney, a doctoral student at the University of Minnesota in Minneapolis. "There's not much research on longer-term health outcomes on high-dose supplements," she said. But studies have hinted at potential harm, such as excess calcium in the blood, which can cause deposits ... Read more

Vitamin D Unlikely to Reduce Risk of Asthma, Allergies or Eczema

Posted 9 May 2017 by Drugs.com

TUESDAY, May 9, 2017 – Vitamin D supplements aren't likely to reduce the risk of asthma, allergies or the skin condition eczema in children or adults, a new study finds. Previous research had suggested that low vitamin D levels were linked with these "atopic" conditions. For the new study, Canadian researchers analyzed data from more than 100,000 people to determine if this was true. The investigators found no statistically significant differences in rates of asthma, allergies or eczema between people with low or normal levels of vitamin D. The results were published online May 9 in the journal PLoS Medicine. "Our findings suggest that previous associations between low vitamin D and atopic disease could be due to spurious associations with other factors," lead study author Despoina Manousaki said in a journal news release. Manousaki is a doctoral student at Lady Davis Institute, the ... Read more

Health Tip: How to Get Enough Vitamin D

Posted 28 Apr 2017 by Drugs.com

-- Sunlight provides much-needed vitamin D, but you have to protect yourself from sun damage and skin cancer. There are other ways to get vitamin D, the Skin Cancer Foundation says, suggesting: A diet rich in fatty fish, such as salmon, mackerel and tuna. Other food sources of the vitamin include egg yolks, beef, liver and cheese. Some beverages are fortified with the vitamin, such as orange juice and milk. Cod liver oil has more than twice the daily recommended amount of vitamin D. Consider a vitamin D supplement. Read more

High-Dose Vitamin D Failed to Curb Heart Disease in Study

Posted 5 Apr 2017 by Drugs.com

WEDNESDAY, April 5, 2017 – Taking high doses of vitamin D once a month won't lower your risk for heart disease, new research indicates. But, even though the vitamin came up short in this study of more than 5,000 adults, the researchers aren't ready to scrap hopes for vitamin D supplementation altogether. "Our study only rules out monthly dosing," said study lead author Dr. Robert Scragg. His team did not explore whether daily vitamin D supplementation might prove more protective of heart health. Scragg is a professor of epidemiology at the University of Auckland in New Zealand. Previous studies have reported higher chances of heart disease among people with low vitamin D intake. Natural sources of vitamin D include ultraviolet radiation from the sun, as well as foods such as fatty fish, fortified dairy products, orange juice and egg yolks. The idea that vitamin D – particularly from ... Read more

High Doses of Vitamin D Fail to Cut Cancer Risk, Study Finds

Posted 28 Mar 2017 by Drugs.com

TUESDAY, March 28, 2017 – High doses of vitamin D supplements may not lower older women's risk of developing cancer, a new clinical trial finds. Many studies have hinted that vitamin D might help ward off cancer. Some, for example, have found that people with higher blood levels of the vitamin have lower rates of certain cancers, including colon and breast cancers. In lab experiments, vitamin D has also shown activities that might slow the growth of cancer – such as, promoting the death of abnormal cells. But those types of studies cannot prove that taking vitamin D actually causes cancer risk to drop, explained Dr. JoAnn Manson, of Brigham and Women's Hospital and Harvard Medical School in Boston. That, Manson said, takes clinical trials that test vitamin D against an inactive placebo. That's exactly what the new study did, but it found no significant benefit. The trial involved ... Read more

Don't Skip Veggies in Winter

Posted 21 Feb 2017 by Drugs.com

MONDAY, Feb. 20, 2017 – Just because it's cold outside doesn't mean you can't eat fresh, healthy foods. There are five types of foods you should try to consume during the winter months, according to health experts at the Cleveland Clinic who offer these suggestions: While it can be hard to find local produce during the winter, root vegetables such as beets, carrots and turnips can withstand the cold and are available. Roast carrots to get a dose of beta-carotene, or boil turnips for vitamins A and C. Oatmeal provides nutrients that are essential during winter. It's high in zinc (important for your immune system) and soluble fiber, which is associated with heart health. Instant oatmeal is more convenient but also more expensive. If you're on a budget, choose old-fashioned oats. Soup is another good food choice in winter, but hold the cream, salt and beef. Try soup recipes that call for ... Read more

Vitamin D Pumps Up Muscles

Posted 17 Feb 2017 by Drugs.com

THURSDAY, Feb. 16, 2017 – High blood levels of "active" vitamin D may boost muscle strength, a new study suggests. British investigators measured both inactive and active vitamin D levels, fat levels and muscle mass in 116 healthy adult volunteers, aged 20 to 74. People with higher levels of active vitamin D in the blood had more lean muscle mass and bulk, the investigators found. "By looking at multiple forms [of vitamin D] in the same study, we can say that it is a more complex relationship than previously thought," said study author Zaki Hassan-Smith, from the University of Birmingham. "It may be that body fat is linked to increased levels of inactive vitamin D, but lean mass is the key for elevated levels of active vitamin D," Hassan-Smith said in a university news release. "It is vital to understand the complete picture, and the causal mechanisms at work, so we can learn how to ... Read more

Vitamin D Linked to Lower Risk of Respiratory Infections

Posted 16 Feb 2017 by Drugs.com

THURSDAY, Feb. 16, 2017 – There's preliminary evidence that adequate amounts of vitamin D might help lower rates of respiratory infections. These infections include colds, bronchitis and pneumonia, the researchers said. In a review of past trials of people taking vitamin D supplements, researchers from Queen Mary University in London found that supplementation was linked to a 12 percent reduction in the proportion of people having an "acute respiratory infection." The researchers said their findings "support the introduction of public health measures such as food fortification to improve vitamin D status in settings where profound vitamin D deficiency is common." But not everyone agrees with the authors of the review, which was published Feb. 15 in the BMJ. The results are inconclusive and need to be confirmed in carefully controlled clinical trials, said Mark Bolland from the ... Read more

Can Extra Time Outdoors When Young Reduce Nearsightedness?

Posted 2 Dec 2016 by Drugs.com

THURSDAY, Dec. 1, 2016 – Spending more time outside early in life may offer some protection against nearsightedness, a new study suggests. The European study authors suspect that additional exposure to the sun's ultraviolet B (UVB) rays may play a role in reducing nearsightedness – the inability to see clearly at a distance, also known as myopia. "We found that higher annual lifetime UVB exposure, directly related to time outdoors and sunlight exposure, was associated with reduced odds of myopia," the study authors wrote. "Exposure to UVB between ages 14 and 29 years was associated with the highest reduction in odds of adult myopia," they added. The findings don't "add a lot to the picture" of current research that links nearsightedness to time outdoors, said Ian Morgan, a vision researcher and visiting fellow at Australian National University. He was not involved with the study. ... Read more

Could Low Vitamin D Levels at Birth Mean Higher MS Risk?

Posted 2 Dec 2016 by Drugs.com

THURSDAY, Dec. 1, 2016 – Newborns with low levels of vitamin D may have higher odds of developing multiple sclerosis (MS) later in life, new research suggests. Vitamin D deficiency is common among the general population, including pregnant women. But the researchers said it's too soon to routinely recommend "sunshine vitamin" supplements for mothers-to-be. "The study does not prove that increasing vitamin D levels reduces the risk of MS. Further studies are needed to confirm our results," said study leader Dr. Nete Munk Nielsen, a researcher at the Statens Serum Institute in Copenhagen, Denmark. About 2.5 million people worldwide have MS. It's a chronic disease of the central nervous system characterized by damage to myelin, the fatty substance coating nerve fibers. MS symptoms vary, but can include walking difficulties, fatigue, numbness and vision problems. A growing body of evidence ... Read more

Vitamin D May Affect Breast Cancer Survival

Posted 10 Nov 2016 by Drugs.com

THURSDAY, Nov. 10, 2016 – Vitamin D levels may affect breast cancer patients' chances of survival, a new study suggests. Researchers analyzed data from nearly 1,700 breast cancer patients in California and found that higher vitamin D levels at diagnosis were associated with better overall survival. This link was strongest in premenopausal women. Researchers found lower vitamin D levels in patients with advanced-stage tumors and the lowest levels in premenopausal women with triple-negative cancer. Triple-negative cancer is the most common type of breast cancer found in women with changes in a gene called BRCA1. While the findings are consistent with previous studies, other factors may play a role and the study does not prove cause and effect, the researchers noted. "Our findings provide compelling observational evidence for inverse associations between vitamin D levels and risk of ... Read more

Low Vitamin D Levels May Raise Bladder Cancer Risk: Study

Posted 8 Nov 2016 by Drugs.com

TUESDAY, Nov. 8, 2016 – Low vitamin D levels may increase the risk of bladder cancer, researchers report. Five of seven studies the researchers reviewed linked low vitamin D levels with an higher risk of bladder cancer. In experiments with the cells that line the bladder, the researchers found that the cells activate and respond to vitamin D. This, in turn, can stimulate an immune response, the study authors said. The finding is important because the immune system may help prevent cancer by identifying and destroying abnormal cells before they develop into cancer, according to lead author Rosemary Bland, an honorary associate professor at the University of Warwick in England. "More clinical studies are required to test this association, but our work suggests that low levels of vitamin D in the blood may prevent the cells within the bladder from stimulating an adequate response to ...
