The B-vitamins (thiamin, riboflavin, vitamin B-6) are necessary in the energy-producing pathways of the body, while folate and vitamin B-12 are required for the synthesis of new cells, such as the red blood cells, and for the repair of damaged cells. Active individuals with poor or marginal nutritional status for a B-vitamin may have decreased ability to perform exercise at high intensities. Th...

Background Bronchopulmonary dysplasia (BPD) is one of the most common serious squeal of preterm infants. It involves approximately one quarter of infants with birth weight less than 1500 grams and 30% of less than 1000 grams. Vitamin A has been shown to reduce BPD rate. We compared efficacy of low and high doses of vitamin A for prevention of BPD in very low birth weight preterm infants. Materi...

BACKGROUND Decreasing or eliminating animal products from the diet decreases the intake of some essential nutrients, such as vitamin B(12), which may lead to hyperhomocysteinemia. We investigated vitamin B(12)-dependent metabolism and oxidative stress in groups with various or no intake of meat or animal products. METHODS We investigated 44 high meat eaters, 19 low meat eaters, 34 lacto-ovo/l...

OBJECTIVES To study the effects of metformin on the incidence of vitamin B-12 deficiency (<150 pmol/l), low concentrations of vitamin B-12 (150-220 pmol/l), and folate and homocysteine concentrations in patients with type 2 diabetes receiving treatment with insulin. DESIGN Multicentre randomised placebo controlled trial. SETTING Outpatient clinics of three non-academic hospitals in the Neth...

Abstract Background A novel gradient, high-sensitive and specific stability-indicating reverse-phase HPLC method was developed validated for quantitative purpose of known, unknown degradant impurities profiling diltiazem hydrochloride tablets. The were separated on the Zorbax RX C8 column (150 mm × 4.6 mm, 5 μm) with mobile phase-A consisting a mixture 0.05 M sodium dihydrogen phosphate monohyd...

The present study was conducted to clarify the relationship between colostral and plasma vitamin A and b-carotene, and to evaluate the effect of vitamin status on diarrhea and anemia of 46 Holstein newborn calves at 6 days of age. Colostral b-carotene and vitamin A concentrations at parturition ranged from 17.8 to 342.9 and from 32.9 to 450.0 mg/dl, respectively. Plasma b-carotene and vitamin A...

Vitamin B Cocktail A daily vitamin B cocktail (vitamin B6, vitamin B12 and folic acid) is among the most important supplements that an afibber, or anyone else for that matter, can take. The vitamin B cocktail effectively lowers the level of homocysteine in the blood. High levels of homocysteine, a sulfurcontaining amino acid, is associated with an increased risk of stroke and is also involved i...

Since the introduction of folic acid fortification of flour 10 y ago, an initiative to consider fortifying flour with vitamin B-12 has gained momentum in the United States. The impetus for this move stems from several considerations, including some evidence that a proportion of neural tube defect pregnancies may be the result of vitamin B-12 rather than folate deficiency. However, no interventi...

The natural source of vitamin B₁₂ in human diets comes from animal products. For example, one glass (250 ml) of milk provides approximately 50 % of the RDA (2·4 μg/d). It was hypothesised that the provision of vitamin B₁₂ from milk is more efficiently absorbed than the synthetic form used in vitamin supplements. Pigs (n 10) were used as a model for intestinal absorption of vitamin B₁₂ in humans...

in order to identify the effects of vitamin b 12 and folic acid in reducing methanolinduced retinopathy, erg waves were compared before and after methanol intoxication in rabbits. in this study 34 rabbits were divided into 4 groups. all groups received 4 g/kg of methanol intraperitoneally. in addition, the second, third and fourth groups received vitamin b 12 injection, oral folic acid and a mi...
