Tanning May Limit Skin's Ability to Produce Vitamin D: Study

Posted 4 Apr 2016 by Drugs.com

MONDAY, April 4, 2016 – While the sun helps the body make vitamin D, a new study says that too much exposure might actually lower the levels of the essential vitamin. Tan skin may provide some protection against the sun's harmful UV rays, but this increase in pigment blocks vitamin D synthesis and limits the skin's ability to produce vitamin D, according researchers in Brazil. "Our findings suggest that skin tanning, which is a natural protection against the harmful effects of UV irradiation, limits the progressive rise in serum vitamin D towards optimal concentrations," said study author Dr. Francisco Bandeira, of the University of Pernambuco Medical School in Recife, Brazil. For the study, researchers examined nearly 1,000 males and females from Recife who were between 13 and 82 years old. All had significant daily sun exposure and none routinely used sunscreen or took vitamin D ... Read more

Be Wary of Imported Supplements: FDA

Posted 9 Mar 2016 by Drugs.com

WEDNESDAY, March 9, 2016 – You could be putting your health at risk if you buy imported dietary supplements and nonprescription drug products, the U.S. Food and Drug Administration warns. Health fraud scammers often sell such products at ethnic or international stores, flea markets, swap meets or online, Cariny Nunez, a public health adviser in the FDA's Office of Minority Health, said in an agency news release. This may be because many people who shop at these places have poor English-language skills and limited access to health care services and information, she suggested. "These scammers know that ethnic groups who may not speak or read English well, or who hold certain cultural beliefs, can be easy targets," she added. For example, Native American, Hispanic, Asian and black people may have a long tradition of using herbal – or so-called "natural" – products, and many of these ... Read more

Low Prenatal Vitamin D Linked to Later MS in Offspring

Posted 8 Mar 2016 by Drugs.com

MONDAY, March 7, 2016 – Children of mothers with too little vitamin D during their pregnancy may have a higher risk of developing multiple sclerosis when they reach adulthood, a new study suggests. One expert in the United States said that the findings need to be interpreted with caution, however. "We cannot say from this study that low vitamin D levels cause MS in women's offspring," said Dr. Daniel Skupski, chair of obstetrics and gynecology at NewYork-Presbyterian/Queens hospital in New York City. All the study points to is an association between the two, he stressed. What the research does do, Skupski said, is "set the stage" for further research to see if getting more vitamin D in pregnancy might lower people's lifetime risk for multiple sclerosis. Multiple sclerosis affects a person's brain and spinal cord by damaging the myelin sheath, the insulating layer that surrounds and ... Read more

Low Vitamin D Levels May Signal More Aggressive Prostate Cancer

Posted 2 Mar 2016 by Drugs.com

WEDNESDAY, March 2, 2016 – Prostate cancer may be more aggressive in men who are deficient in vitamin D, new research suggests. A study of nearly 200 men having their prostate removed found those with low vitamin D levels were more likely to have rapidly growing tumors than those with normal levels of the "sunshine" vitamin. "If men with vitamin D deficiency are more likely to have [more advanced disease] at the time of prostate surgery, then perhaps men should be tested for this when they are diagnosed with prostate cancer and subsequently supplemented with vitamin D if they are deficient," said researcher Dr. Adam Murphy. He is an assistant professor of urology at Northwestern University in Chicago. However, another expert isn't ready to go that far. This study can't prove that vitamin D deficiency causes aggressive prostate cancer, only that the two are associated, said Dr. Anthony ... Read more

Could High-Dose Vitamin D Help Fight Multiple Sclerosis?

Posted 31 Dec 2015 by Drugs.com

WEDNESDAY, Dec. 30, 2015 – High-dose vitamin D appears safe for people with multiple sclerosis, and it may help quiet the immune system hyperactivity that marks the disease, a small clinical trial finds. The study, published online Dec. 30 in Neurology, bolsters evidence that vitamin D might benefit people with MS. But clinical trials are still underway to answer the big question: Does taking vitamin D improve MS symptoms and alter the course of the disease? The current study shows only that high doses – 10,400 IU a day – reduce the proportion of certain immune-system cells that have been implicated in the MS disease process. "I'm not going to make any claims beyond that," said senior researcher Dr. Peter Calabresi, a professor of neurology at Johns Hopkins University in Baltimore. "We don't have enough data here to guide clinical practice," he stressed. Bruce Bebo, executive vice ... Read more

Vitamin D Won't Guard Against Colds in People With Asthma

Posted 10 Dec 2015 by Drugs.com

THURSDAY, Dec. 10, 2015 – If you have asthma, vitamin D supplements won't protect you against colds, new research suggests. The study found that taking vitamin D supplements didn't reduce the number or severity of colds in adults with mild-to-moderate asthma. More than 400 participants, all of whom had low vitamin D levels, took either vitamin D supplements or a placebo for 28 weeks. During that time, about half of them got at least one cold. Eighty-two percent of those in the supplement group had sufficient levels of vitamin D after 12 weeks, but that didn't boost their resistance to colds, the research revealed. The study was published recently in the American Journal of Respiratory and Critical Care Medicine. The findings surprised the researchers because they had previously shown that asthma flare-ups fell 40 percent in patients who took vitamin D supplements to increase low levels ... Read more

Many Hospital Patients Not Asked About Supplements: Study

Posted 23 Jun 2015 by Drugs.com

TUESDAY, June 23, 2015 – Most hospitalized Americans aren't asked if they take dietary supplements, such as multivitamins, a new study suggests. "If clinicians are unaware of possible drug-[dietary supplement] reactions, they may unknowingly provide a treatment plan or prescribe medications that could have an adverse reaction or interactions with the dietary supplement," said study author Dr. Paula Gardiner. She is assistant director of Boston Medical Center's program for integrative medicine and health care disparities. "Dietary supplements also affect physiological processes in the body and could have an impact on medical procedures like surgery, chemotherapy, blood work and many other treatments or procedures," she added in a medical center news release. Nearly 18 percent of American adults (more than 40 million) take dietary supplements, according to the 2012 National Health ... Read more

Low Vitamin D Levels in Stroke Survivors a Bad Sign, Study Finds

Posted 12 Feb 2015 by Drugs.com

THURSDAY, Feb. 12, 2015 – Low vitamin D levels are linked to an increased risk of suffering a severe stroke and poor health in stroke survivors, new research finds. The study included almost 100 stroke patients who were treated at a U.S. hospital between 2013 and 2014. All had experienced an ischemic stroke, which is a stroke caused by blocked blood flow to the brain. People with low blood levels of vitamin D – less than 30 nanograms per milliliter (ng/mL) – had about two times larger areas of stroke-related dead brain tissue than those with normal vitamin D levels, according to the study. The researchers also found that for each 10 ng/mL reduction in vitamin D level, the odds of a healthy recovery in the three months after stroke fell by about half, regardless of age or initial stroke severity. Although this study found an association between low vitamin D levels and poor stroke ... Read more

Low Vitamin D Levels in Childhood May Raise Heart Risks: Study

Posted 10 Feb 2015 by Drugs.com

TUESDAY, Feb. 10, 2015 – Adults who had low vitamin D levels as children and teens may be more likely to have hardening of the arteries, a new study suggests. Artery hardening is associated with heart disease. The study included more than 2,100 people in Finland. Their vitamin D levels were measured at ages 3 to 18, and they were checked for artery hardening at ages 30 to 45. Those with the lowest vitamin D levels when they were youngsters had a much higher risk for artery hardening as adults, according to the study published online Feb. 10 in the Journal of Clinical Endocrinology & Metabolism. This link was independent of other heart disease risk factors such as high blood pressure, smoking, poor eating, lack of exercise and obesity. Only an association was seen between childhood vitamin D levels and later heart health. The study did not prove a cause-and-effect relationship. Further ... Read more

Low Vitamin D Levels Linked to Risk of Preterm Birth in Study

Posted 8 Jan 2015 by Drugs.com

THURSDAY, Jan. 8, 2015 – Women who have low blood levels of vitamin D during pregnancy are more likely to give birth prematurely, a new study suggests. Women with the lowest levels of vitamin D were about 1.5 times as likely to deliver early compared to those with the highest levels, the investigators found. That finding held true even after the researchers accounted for other factors linked to preterm birth, such as overweight and obesity, and smoking. "Mothers who were deficient in vitamin D in early parts of pregnancy were more likely to deliver early, preterm, than women who did not have vitamin D deficiency," said Lisa Bodnar, associate professor of epidemiology and obstetrics and gynecology at the University of Pittsburgh, who led the study. Although this study found a strong association between vitamin D levels and preterm birth, Bodnar noted that the study wasn't designed to ... Read more

Low Levels of Vitamin D May Raise Early Death Risk: Study

Posted 19 Nov 2014 by Drugs.com

WEDNESDAY, Nov. 19, 2014 – Having low levels of vitamin D because of your genetics may raise the risk of early death, a new study suggests. But the risk is not linked with early death due to heart-related causes, the researchers added. The study, by Borge Nordestgaard of Herlev Hospital, Copenhagen University Hospital in Herlev, Denmark, and colleagues involved more than 95,000 white people of Danish descent in Copenhagen. The participants, who were from three different groups, had genetic variants known to affect levels of vitamin D. The researchers also considered other factors that could affect the participants' vitamin D levels, such as smoking, drinking alcohol, physical activity levels, blood pressure, cholesterol levels and body mass index (a measurement that helps determine if a person is a normal weight for their height). By the time the study ended in 2013, more than 10,000 ... Read more

Gene Study Finds No Proof Vitamin D Guards Against Type 2 Diabetes

Posted 1 Oct 2014 by Drugs.com

TUESDAY, Sept. 30, 2014 – There's no genetic evidence that high levels of vitamin D can prevent type 2 diabetes, a new study says. Some previous research had suggested that elevated levels of vitamin D might protect people against type 2 diabetes, raising the possibility of a link between vitamin D deficiency and the blood sugar disease. In this study, British researchers investigated the association between diabetes risk and vitamin D by focusing on genes that control blood levels of vitamin D. They found no connection between different variants of these genes and the risk of developing type 2 diabetes. The results were published Sept. 30 in The Lancet Diabetes & Endocrinology. "Our findings suggest that interventions to reduce the risk of type 2 diabetes by increasing concentrations of vitamin D are not currently justified. Observational studies that show a strong and consistent ... Read more

Women's Vitamin D Levels May Play Role in IVF Success

Posted 14 Aug 2014 by Drugs.com

THURSDAY, Aug. 14, 2014 – Vitamin D deficiency may lower a woman's chances of getting pregnant through in vitro fertilization (IVF), a small study suggests. Researchers in Italy compared the success of IVF in 154 women with vitamin D deficiency against that of 181 women with sufficient levels of vitamin D. Those with sufficient vitamin D levels were twice as likely to get pregnant as those with vitamin D deficiency, the team reported Aug. 14 in the Journal of Clinical Endocrinology & Metabolism Women with sufficient levels of vitamin D were also more likely to have better-quality embryos and had a greater likelihood of an embryo implanting in the uterus, the study found. According to the study authors, vitamin D levels of 20 to 30 nanograms per milliliter in their blood are considered sufficient or healthy, so the vitamin D-deficient women fell below that threshold. The study does not ... Read more

Low Vitamin D Levels May Boost Alzheimer's Risk, Study Finds

Posted 6 Aug 2014 by Drugs.com

WEDNESDAY, Aug. 6, 2014 – Older adults with too little vitamin D in their blood may have twice the risk of developing Alzheimer's disease as seniors with sufficient levels of the "sunshine vitamin," a new study finds. The research – based on more than 1,600 adults over age 65 – found the risk for Alzheimer's and other forms of dementia increased with the severity of vitamin D deficiency. But the findings aren't enough to recommend seniors take vitamin D supplements to prevent mental decline. "Clinical trials are now urgently needed in this area," said study researcher David Llewellyn, a senior research fellow in clinical epidemiology at the University of Exeter Medical School in England. Another expert agreed. "This shows you there is a link between vitamin D and the development of Alzheimer's," said Keith Fargo, director of scientific programs and outreach for the Alzheimer's ...

Low Vitamin D Levels Linked to High Blood Pressure

Posted 28 Jun 2014 by Drugs.com

THURSDAY, June 26, 2014 – Low levels of vitamin D may be a cause of high blood pressure, according to a new study. Previous research has suggested a strong link between low levels of vitamin D and high blood pressure, but a direct cause-and-effect relationship has not been shown. Vitamin D is nicknamed the sunshine vitamin because the body produces vitamin D when exposed to sunlight. People also get vitamin D through foods such as eggs, milk, yogurt, tuna, salmon, cereal and orange juice. In the new study, researchers analyzed genetic data from more than 146,500 people of European descent in Europe and North America. For each 10 percent increase in vitamin D levels, there was an 8 percent decrease in the risk of developing high blood pressure (or "hypertension"). The study was published online June 25 in The Lancet Diabetes & Endocrinology. "In view of the costs and side effects ... Read more
