Vitamin D Cut Point Linked to Normal Glucose Metabolism
Apr 22, 2014

A 25-hydroxyvitamin D (vitamin D) level of about 26 ng/mL is needed for normal glucose metabolism in both black and white obese, postmenopausal women, a new observational study suggests. Women with a blood vitamin-D concentration at or above this threshold had lower body fat and blood glucose, insulin, and triglyceride levels than women with lower levels of vitamin D.

Low Vitamin D in Mothers Tied to Cavities in Babies
Apr 21, 2014

Low levels of vitamin D in pregnancy are associated with the development of cavities in babies, researchers report.

The scientists studied 134 expectant mothers, average age 19. Each provided information on health behavior and socioeconomic status and gave blood samples to measure vitamin D levels.

Their children had dental examinations when they were an average of 1 year old, and their mothers completed another questionnaire on breast-feeding, introduction of solids and other health and behavioral factors.

About a third of the women were deficient in vitamin D, 22 percent of the infants had deficient or thinning enamel and 23 percent had cavities.

Vitamin D deficiency doubles risk of chronic musculoskeletal pain
Apr 17, 2014

A lack of vitamin D can double the risk of developing chronic widespread pain, a study suggests.

Men with vitamin D deficiency were more than twice as likely to develop chronic widespread pain as those with the highest levels, researchers from the University of Manchester found.

In the four-year study of 2,313 middle-aged men, one in 15 developed chronic widespread pain. These men were more likely to be depressed, obese, physically inactive and have other health problems.

Study examines vitamin D deficiency and cognition relationship
Apr 16, 2014

Vitamin D deficiency and cognitive impairment are common in older adults, but there isn't a lot of conclusive research into whether there's a relationship between the two.

A new study from Wake Forest Baptist Medical Center published online ahead of print this month in the Journal of the American Geriatrics Society enhances the existing literature on the subject.

"This study provides increasing evidence that suggests there is an association between low vitamin D levels and cognitive decline over time," said lead author Valerie Wilson, M.D., assistant professor of geriatrics at Wake Forest Baptist. "Although this study cannot establish a direct cause and effect relationship, it would have a huge public health implication if vitamin D supplementation could be shown to improve cognitive performance over time because deficiency is so common in the population."

Vitamin D deficiency contributes to poor mobility among severely obese people
Apr 16, 2014

Among severely obese people, vitamin D may make the difference between an active and a more sedentary lifestyle, according to a new study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).

The study found severely obese people who also were D-deficient walked slower and were less active overall than their counterparts who had healthy vitamin D levels. Poor physical functioning can reduce quality of life and even shorten lifespans.

Severe obesity occurs when a person's body mass index (BMI) exceeds 40. About 6.5 percent of American adults are severely obese.

Health: Study shows 4 million Australians deficient in Vitamin-D
Apr 16, 2014

Almost 4 million Australians are not getting enough vitamin D, data released by the Bureau of Statistics shows.

In the most wide-ranging survey of the nutrient to date, researchers found that levels of the vitamin varied wildly between seasons. Deficiency rates soared to almost 50 per cent for those living in Victoria and the ACT during winter.

Specialists say this is a warning that people are limiting their exposure to the sun by spending too much time indoors, thereby increasing their risk of poor bone health and chronic disease due to poor levels of the vitamin.

Getting outside: More than 1.1 million people had moderate to severe deficiency in vitamin D.

''It's a real problem which alerts the population that we shouldn't dismiss it,'' Rebecca Mason, a professor of physiology at the University of Sydney's Bosch Institute, said.

She said Australians needed at least 10 minutes of exposure to the sun on the arms during mid-morning or afternoon in summer to receive adequate vitamin D, which is absorbed through the sun's ultraviolet-B rays.

''We are spending far too much time indoors watching television and using technology,'' Professor Mason said. ''We're just not getting out there enough - with or without sunscreen.''

Higher Vitamin D Does Not Raise the Risk for Kidney Stones

The Vitamin D Society wants to make the public aware of a recent study which reported that high levels of vitamin D had a lower risk of kidney stones.

Woodstock, ON (PRWEB) November 29, 2013

The Vitamin D Society wants to make the public aware of a recent study published in the American Journal of Public Health, which reported that study participants with the highest vitamin D blood serum levels actually had a lower incidence of kidney stones(1). These results show that higher vitamin D intake cannot be a substantial cause of kidney stones because as participants vitamin D levels increased, kidney stone cases actually decreased. The study was sponsored by GrassrootsHealth (GRH), a nonprofit public health research organization, and was led by Dr. Cedric Garland, professor of family and preventive medicine at the University of California San Diego. The research team used data collected from 2,012 participants enrolled in GrassrootsHealth’s D*action study. This study is the first of its kind to include participants with a wide range of 25(OH)D blood serum levels, especially on the higher end of the spectrum between 100 nmol/L and 250 nmol/L, and is therefore a more rigorous test of the suggested association with kidney stones than previous studies.

Vitamin D Levels Start Plunging in November

November is Vitamin D Awareness Month and the Vitamin D Society is urging all Canadians to check their vitamin D blood levels to ensure that they are not deficient. Canadians will no longer be able to make vitamin D from sunlight (UVB Light).

Woodstock, ON (PRWEB) November 22, 2013

November is Vitamin D Awareness month. A time of the year when your body’s vitamin D level starts to decrease dramatically as the reserves of vitamin D built up through summer sunshine rapidly deplete. November is the start of vitamin D winter in the northern hemisphere. In Canada the sun is low in the sky and the UVB rays that produce vitamin D in your skin do not reach the earth. People retreat indoors to bear the long, cold, low light Canadian winter. The Vitamin D Society is urging all Canadians to check their vitamin D levels through a 25(OH)D blood serum test, get their test score and ensure that they are at the optimal levels of 100-150 nmol/L as recommended by over 40 of the top vitamin D scientific researchers at GrassrootsHealth(1). If you are unable to test your vitamin D levels, Dr. Robert Heaney MD, Creighton University, recommends that you ensure your vitamin D intake is approximately 35IU per pound of body weight per day (75 IU per Kg/day).

November is the start of the season when most Canadians become vitamin D deficient due to lack of sunlight. The Vitamin D Society is asking all Canadians to assess their vitamin D levels on Vitamin D Day November 2nd and to take action to prevent vitamin D deficiency.

Woodstock, ON (PRWEB) October 31, 2013

The Vitamin D Society is asking all Canadians to join us to celebrate Vitamin D Day on November 2nd and to assess their personal vitamin D blood levels and to take action to prevent a possible vitamin D deficiency. “Canadians should check their vitamin D level through a 25(OH)D blood serum test (ask for your test score) and ensure they are between the optimal levels of 100 – 150 nmol/L as recommended by over 40 of the top Vitamin D researchers at GrassrootsHealth(1)” stated Perry Holman, executive director of the Vitamin D Society
