Hematological changes and serum iron, vitamin B12 and folate levels after administration of iron plus folic acid were com· pared with changes and levels after supplement of iron alone in 100 pregnant women. No hematological benefits by adding folic acid was revealed. It is concluded that folic acid deficiency in pregnant women is mild and routine supplementation of folic acid is not necessary e...

Iron oxide is an important biological agent that has a key role in medical processes; however, the mechanism whereby it provides iron for human and animal cells and its biological uses remains unclear. We aimed to evaluate the effects of oral iron oxide on serum iron status and compare the results with those of iron sulfate as a reference salt. Fifteen adult rabbits were divided into 3 groups o...

Pediatricians and hematologists alike should take keen interest in the report by Taylor and Kennedy in this issue of Pediatrics of a randomized, placebo-controlled study of daily oral iron supplementation in very low birth weight (VLBW) infants ,36 weeks’ postgestational age. Study subjects, managed according to relatively liberal transfusion guidelines, derived no benefit from the additional i...

Many N-nitroso compounds (NOC) are carcinogens. In this controlled study of 21 healthy male volunteers, levels of NOC on a high (420 grams) red meat diet were significantly greater (P = 0.001) than on a low (60 grams) meat diet but not significantly greater when an equivalent amount of vegetable protein was fed. An 8-mg supplement of haem iron also increased fecal NOC (P = 0.006) compared with ...

BACKGROUND Iron deficiency is common during pregnancy. Experimental animal studies suggest that it increases cardiovascular risk in the offspring. OBJECTIVE To examine the relationship between maternal pregnancy dietary and supplement iron intake and hemoglobin, with offspring's arterial stiffness (measured by carotid-radial pulse wave velocity), endothelial function (measured by brachial art...

Background Iron deficiency anemia is a global health problem, and approximately 50% of anemia is caused by iron deficiency. According to studies, iron supplementation in young females improves iron status by increasing concentration of hemoglobin. To compare of prescribing two methods of iron supplementation administered either on a weekly basis or during menstruation, on hemoglobin level and...

BACKGROUND Owing to the mechanics of anti-doping regulation via the World Anti-Doping Agency's Prohibited List, nutritional supplement use received little attention in comparison to the prevalence of doping. The aims of this study were to investigate supplement use, identify groups of athletes with high levels of supplement use and the prevalence of concomitant use of supplements. METHODS Sur...

OBJECTIVE To measure nutrient intake adequacy of vitamin/mineral supplement users and nonusers aged 51 years and older, determine the efficacy of supplement practices in compensating for dietary deficits, and identify predictors of supplement use. DESIGN Analyses of two 24-hour recalls, demographic variables, and attitude questions collected during the Continuing Survey of Food Intakes by Ind...
