First study to examine vitamin D insufficiency in pediatric patients with low bone density

Vitamin D insufficiency is common in adults and is emerging in the world of pediatrics. A mild degree of vitamin D deficiency, also known as vitamin D insufficiency, causes rickets in children and can be treated with increased amount of nutritional vitamin D intake as well as increased sun exposure.

Trends of vitamin B6 status in US population sample identified in study

In an epidemiological study, Tufts University researchers identified trends of vitamin B6 status in a sample of the United States population based on measures of plasma pyridoxal 5'- phosphate (PLP) levels in the bloodstream. Plasma PLP is the indicator used by the federal government to set the current Recommended Dietary Allowance (RDA) of vitamin B6, a nutrient essential for red blood cell function and important for maintaining a healthy immune system and blood glucose levels.

How humans make up for an 'inborn' vitamin C deficiency

A new study appears to explain how humans, along with other higher primates, guinea pigs and fruit bats, get by with what some have called an “inborn metabolic error”: an inability to produce vitamin C from glucose.

Calcium and vitamin D is more effective than calcium alone in preventing bone loss in elderly women

Previous studies have shown that high calcium intake can help prevent bone loss. This latest study, however, demonstrated that calcium therapy, although initially successful at preventing bone loss, was no different from placebo after three or five years.

Vitamin B-12 function may be diminished by excessive folate

In a study of adults aged 20 and over, researchers at Tufts University showed that homocysteine and methylmalonic acid are at much higher levels in individuals who have a combination of vitamin B12 deficiency and high blood folate levels than in individuals who are also vitamin B12 deficient but have normal folate levels.

Human health, agriculture and the environment to benefit from bioengineering project at the University of Kent

Martin Warren, Professor of Biochemistry at the University of Kent’s Department of Biosciences, has been awarded over £750,000 from the Biotechnology and Biological Sciences Research Council for a study into biochemical pathways that could ultimately lead to improved health benefits for humans, as well as the development of important new technologies and products for agriculture and bioremediation (the use of plants or microorganisms to clean up pollution or contaminated material).
