Urinary excretion of B-group vitamins reflects the nutritional status of B-group vitamins in rats

We have reported previously that the urinary excretion of B-group vitamins reflects recent dietary intakes of these vitamins. We also proposed reference values for the urinary levels of B-group vitamins for human subjects, and used these for evaluating human nutritional status. However, the question arises as to whether the urinary excretion of B-group vitamins in animals or human subjects decr...

Role of B Vitamins in Biological Methylation

B-vitamins and prevention of dementia.

Elevated plasma homocysteine (Hcy) concentrations have been implicated with risk of cognitive impairment and dementia, but it is unclear whether low vitamin B12 or folate status is responsible for cognitive decline. Most studies reporting associations between cognitive function and Hcy or B-vitamins have used a cross-sectional or case-control design and have been unable to exclude the possibili...

B vitamins, cognition, and aging: a review.

Recent research has highlighted the potential impact of nutritional factors and individual micronutrients on the brain and on cognitive performance, especially in older adults. The B vitamins, folate, B12, and B6, are of particular interest because even subclinical deficiencies in these vitamins are thought to be relatively common in the general population and in older adults in particular. Rec...

The B Vitamins and Fat Metabolism

Previous work has shown that rice polish concentrate, used as a dietary supplement in conjunction with thiamine and riboflavin, caused a marked increase in the body fat of rats (1). Bender and Supplee (2) found that, under such conditions, this concentrate had a supplemental effect upon body weight. They correlated the weight changes with the presence or absence of dermatitis, interpreting thei...
