Link Between Vitamin D and Dementia Risk Confirmed

By University of Exeter August 13, 2014 No comments


Vitamin D deficiency is associated with a substantially increased risk of dementia and Alzheimer’s disease in older people, according to the most robust study of its kind ever conducted.

An international team, led by Dr David Llewellyn at the University of Exeter Medical School, found that study participants who were severely Vitamin D deficient were more than twice as likely to develop dementia and Alzheimer’s disease.

The team studied elderly Americans who took part in the Cardiovascular Health Study. They discovered that adults in the study who were moderately deficient in vitamin D had a 53 per cent increased risk of developing dementia of any kind, and the risk increased to 125 per cent in those who were severely deficient.

Similar results were recorded for Alzheimer’s disease, with the moderately deficient group 69 per cent more likely to develop this type of dementia, jumping to a 122 per cent increased risk for those severely deficient.

Success as a professional soccer player during the World Cup requires skill, training and heart. A new study found that vitamin D levels could also impact athletic performance.

Researchers from Greece looked at the vitamin D levels of 67 soccer players following the competition season and off season. They found high vitamin D levels related to increased exercise performance both times.

Higher Vitamin D Levels Cut Risk of Dying By Half

By Res-Q Editor July 2, 2014 No comments

Research confirms that having a healthy vitamin D blood serum level of 30 ng/mL (nanograms per milliliter—a density measurement) cuts the risk of dying prematurely in half, over a nine-year follow-up, compared to people with lower levels.

The Institute of Medicine (IOM) concluded that too-low levels of vitamin D are hazardous due to increased risk of bone diseases. The results of this new systematic review as published in the American Journal of Public Health go even further in showing a connection between vitamin D and risk of premature death from all causes.

Unfortunately, nearly two-thirds of Americans are estimated to have vitamin D levels lower than 30 ng/mL, according to Dr. Cedric Garland, a professor in the Department of Family and Preventive Medicine at UC San Diego.

Low Levels of Vitamin D Linked to Increased Risk of High Blood Pressure

By Res-Q Editor June 30, 2014 No comments

A recent study published online in the June 25, 2014 issue of The Lancet: Diabetes and Endocrinology found a causal link between vitamin D deficiencies and the risk of hypertension (high blood pressure).

This large and very interesting study involved more than 140,000 individuals across Europe and North America.  The researchers found that for every 10 percent increase in vitamin D levels, there was an 8 percent decrease in the risk of developing high blood pressure.    

“The potential to prevent and reduce high blood pressure with vitamin D in place of more expensive medications is certainly something researchers can now usefully explore in greater depth,” said study leader Professor Elina Hypponen of the University of South Australia

Though additional research is needed, these findings suggest that Vitamin D supplementation could be effective in combating some cases of hypertension.  Res-Q offers three health supplements with Vitamin D:  

  • Multi – an all-purpose multi-vitamin with 800 IU of Vitamin D
  • SmartCal – helps promote strong bones with 1,000 IU of Vitamin D
  • 1250+ - Combines the beneficial effects of Omega-3 with 500 IU of Vitamin D
