How global health authorities view Iron Deficiency Anemia.
Major health bodies like the WHO and NIH emphasize iron supplementation as the primary treatment for iron deficiency anemia, often alongside dietary modifications. They highlight the importance of identifying and treating the underlying cause of iron deficiency. While some traditional remedies are rich in iron, these organizations generally recommend conventional iron supplements due to their proven efficacy and controlled dosing. The NCCIH acknowledges the use of certain herbs in traditional medicine but stresses the need for more scientific research to support their use for anemia.

Oral iron (Fe) supplementation is one of the mainstays of treatment for iron deficiency anemia (IDA). However, its therapeutic effects are limited when there is poor absorption from the gastrointestinal tract. Vitamin C is hypothesized to improve uptake when combined as an adjunct agent. We aimed to determine the difference in hematologic outcomes in patients with IDA receiving oral iron, with or without vitamin C. MEDLINE, Embase, Web of Science, and Cochrane Central Register of Controlled Trials were searched from database inception to July 2023 for studies investigating the use of oral iron supplements with vitamin C in patients with IDA. The primary outcome was the change in serum hemoglobin (Hb). Secondary outcomes include change in serum ferritin, reticulocyte percentage, and incidence of adverse events. A total of 2231 studies were retrieved; 10 randomized control trials (n = 1782), and 1 prospective cohort study (n = 148) comprising 1930 patients were includ

Iron deficiency anemia (IDA) is one of the leading causes of anemia, globally. Oral vitamin C enhances iron absorption and is commonly prescribed with iron for anemia patients. Considering the lack of evidence to support this practice, we conducted this systematic review and meta-analysis to determine the treatment efficacy of experimental studies where oral vitamin C or ascorbate was given as co-intervention with iron compared to providing only iron among participants with anemia of all ages. A comprehensive strategy was used to search literature from PubMed, Cochrane and Google Scholar. Experimental studies conducted among participants with lab-confirmed anemia at baseline, with "oral ascorbic acid or vitamin C given as co-intervention with iron" as intervention and "only oral iron" as the comparator, and reported the outcomes hemoglobin or ferritin, were selected. Random-effects model was used to estimate standardized mean differences or odds ratio of outcomes, and sensitivity anal

Iron deficiency anemia in males: a dosing dilemma?
Sheikh AB, Javed N, Ijaz Z, Barlas V, Shekhar R, Rukov B · Journal of community hospital internal medicine perspectives · 2021
Introduction: Iron deficiency anemia is a major problem worldwide treated by replenishment of iron stores. The treatment is complicated by differing pharmacodynamics of administrative routes, equations with design effects, ongoing losses, additional daily requirement, plateauing of markers required for iron absorption, food-drug interactions, gender, and age. Accounting for these factors in one dosing regimen becomes difficult, specifically in males. This review aimed at analyzing multiple dosages of iron supplements in different studies and determining if there are factors that could individualize treatment in male patients. Methods: A scoping review was performed using PubMed, Google Scholar, and ClinicalTrials.gov. We reviewed literature from 1980 to 2020. The keywords used in the review were 'iron deficiency', 'dosage', 'males', and 'standardized'. Results and conclusions: The review included 1507 male participants from 9 major studies (4 clinical trials, 1 systematic review, 2 pro

Iron deficiency is the leading cause of anemia during pregnancy. According to survey data from 1999 to 2006, overall estimated prevalence of iron deficiency during pregnancy is near 18% and increases across the 3 trimesters of pregnancy (from 6.9% to 14.3% to 28.4%). An estimated 5% of pregnant persons have iron deficiency anemia. The US Preventive Services Task Force (USPSTF) commissioned a systematic review to evaluate the evidence on the benefits and harms of screening and supplementation for iron deficiency with and without anemia on maternal and infant health outcomes in asymptomatic pregnant persons. Asymptomatic pregnant adolescents and adults. The USPSTF concludes that the current evidence is insufficient, and the balance of benefits and harms of screening for iron deficiency and iron deficiency anemia in asymptomatic pregnant persons on maternal and infant health outcomes cannot be determined. The USPSTF also concludes that the current evidence is insufficient, and the bala

Background/Objectives. Iron deficiency is one of the most common nutritional deficiencies worldwide and is the leading cause of anemia in the pediatric population (microcytic, hypochromic anemia due to iron deficiency). Moreover, untreated iron deficiency can lead to various systemic consequences and can disrupt the child's development. Methods/Results. Therefore, a team of experts from the Polish Pediatric Society, the Polish Society of Pediatric Oncology and Hematology, the Polish Neonatology Society, and the Polish Society of Family Medicine, based on a review of the current literature, their own clinical experience, and critical discussion, has developed updated guidelines for the diagnosis, prevention, and treatment of iron deficiency in children from birth to 18 years of age. These recommendations apply to the general population and do not take into account the specifics of individual conditions and diseases.

Background Iron-deficiency anemia (IDA) is a common nutritional disorder marked by low hemoglobin and impaired oxygen transport, leading to fatigue and reduced quality of life. This study assessed the efficacy and safety of two plant-based iron formulations in adults with IDA. Plant-based iron supplements were investigated to overcome some of the shortcomings of conventional synthetic iron formulations, which are often associated with gastrointestinal intolerance, poor absorption, and oxidative stress. Methods A randomized, double-blind, placebo-controlled trial was conducted in 96 adults (males and non-pregnant, non-lactating females) aged 26-55 years with hemoglobin levels between 8-11 mg/dL. Participants were assigned to one of three groups for 60 days as follows: group A received 18 mg of plant-based iron from Murraya koenigii (Orgen-I) and 90 mg of vitamin C from Phyllanthus emblica (Orgen-C), group B received 18 mg of plant-based iron alone, and group C received a place

Adding vitamin C-rich fruit to staples containing iron could be an effective strategy to improve iron bioavailability and thereby reduce iron-deficiency anemia in children. We aimed to assess the effect of consuming a mungbean-based meal with or without guava fruit on body iron stores, hemoglobin concentration, and anemia of children as part of a school feeding program. We conducted a 7-mo randomized, controlled trial with 6- to 10-y-old school children (n = 200; 46% anemic, 71% iron-deficient) from a rural community in Haryana, North India. Children were assigned to 2 treatment groups to daily receive either a meal of mungbean dal only (3.0 mg iron; vitamin C:iron molar ratio ∼0.5:1), or mungbean dal with fresh guava (3.2 mg iron; ∼170 mg vitamin C; molar ratio ∼18:1). Meals were served every school day under supervision. The primary outcome was body iron stores, whereas concentrations of hemoglobin and other iron indicators were secondary outcomes. Daily consu

The aim of this study was to determine whether iron deficiency anemia (IDA) in mothers alters their maternal cognitive and behavioral performance, the mother-infant interaction, and the infant's development. This article focuses on the relation between IDA and cognition as well as behavioral affect in the young mothers. This prospective, randomized, controlled, intervention trial was conducted in South Africa among 3 groups of mothers: nonanemic controls and anemic mothers receiving either placebo (10 microg folate and 25 mg vitamin C) or daily iron (125 mg FeS0(4), 10 microg folate, 25 mg vitamin C). Mothers of full-term normal birth weight babies were followed from 10 wk to 9 mo postpartum (n = 81). Maternal hematologic and iron status, socioeconomic, cognitive, and emotional status, mother-infant interaction, and the development of the infants were assessed at 10 wk and 9 mo postpartum. Behavioral and cognitive variables at baseline did not differ between iron-deficient anemic mothe

Maternal iron deficiency anemia is a persistent global health challenge with increased risk of adverse perinatal outcomes. Obstetric guidelines advocate for first-line treatment of moderate iron deficiency anemia with twice-daily oral iron; however, rates of iron deficiency anemia in pregnancy remain above global targets and are rising. Determine whether single-dose intravenous iron for primary treatment of maternal iron deficiency anemia in the second trimester is superior to twice daily oral iron in reducing incidence of low birth weight infants and maternal anemia at delivery. This is a parallel, 3-arm, semiblind superiority randomized controlled multicenter trial across 4 sites in India from March 15, 2021-May 12, 2023. Participants were singleton pregnancies at 14 to 17 weeks with moderate iron deficiency anemia (hemoglobin 7.0-9.9 g/dL) who were randomized 1:1:1 to (1) 60 mg oral ferrous sulfate twice daily; or single-dose infusion of (2) intravenous ferric derisomaltose or (3)
Correlation between serum vitamin levels and gestational diabetes mellitus.
Qin Y, Song Q, Jiang X, Su Y, Chen H, Ji X · Frontiers in endocrinology · 2025
Gestational diabetes mellitus (GDM) is a common clinical complication during pregnancy, with its pathogenesis not yet fully elucidated. Vitamin D contributes to GDM pathogenesis by regulating pancreatic β-cell function, immune responses, and lipid metabolism. Vitamin D deficiency may contribute to GDM through these mechanisms. Vitamin E levels in GDM patients are lower than those in normal pregnant women, and its deficiency may increase the risk of GDM, potentially due to its antioxidant properties, although the specific mechanisms remain unclear. The relationship between vitamin A levels and GDM is controversial. Additionally, the occurrence of GDM is closely associated with one-carbon metabolism, involving folic acid (vitamin B9), vitamin B12, and vitamin B6. Deficiencies in these vitamins may lead to homocysteine metabolism disorders, thereby contributing to GDM. Vitamin B3 plays a protective role against GDM by regulating redox reactions. Vitamin C deficiency has also been li
Prenatal Care: An Evidence-Based Approach.

Well-coordinated prenatal care that follows an evidence-based, informed process results in fewer hospital admissions, improved education, greater satisfaction, and lower pregnancy-associated morbidity and mortality. Care initiated at 10 weeks or earlier improves outcomes. Identification and treatment of periodontal disease decreases preterm delivery risk. A prepregnancy body mass index greater than 25 kg per m2 is associated with gestational diabetes mellitus, hypertension, miscarriage, and stillbirth. Advanced maternal and paternal age (35 years or older) is associated with gestational diabetes, hypertension, miscarriage, intrauterine growth restriction, aneuploidy, birth defects, and stillbirth. Rho(D) immune globulin decreases alloimmunization risk in a patient who is RhD-negative carrying a fetus who is RhD-positive. Treatment of iron deficiency anemia decreases the risk of preterm delivery, intrauterine growth restriction, and perinatal depression. Ancestry-based genetic risk stra

Nano-encapsulated Iron and Folic Acid-Fortified Functional Yogurt Enhance Anemia in Albino Rats.
Darwish AMG, Soliman TN, Elhendy HA, El-Kholy WM · Frontiers in nutrition · 2021
Iron deficiency anemia (IDA) is a major health concern in developing countries, and these see an increased incidence in pregnant women and children in particular. The contribution of dairy products as natural products in drug delivery approaches is inspiring. This study aimed to analyze the application of iron (Fe) and folic acid (FA) bovine serum albumin-nanoparticles (BSA-NPs) as anti-anemic pharmacological agents that fortify stirred functional yogurt (SFY), comparing these with a plain control and SFY fortified with Fe and FA in free forms. The physicochemical, cytotoxicity, microbiological, viscosity, oxidative interactions, microstructural, sensorial analyses, and bioavailability properties of IDA-induced Albino rats were examined. The Transmission Electron Microscope (TEM), Zetasizer, and Scan Electron Microscope (SEM) were applied. Nanocapsule-fortified SFY showed an enhanced apparent viscosity, water-holding capacity, microstructure, least lipid oxidation, and overall sensoria
Interaction of vitamin C and iron.
Lynch SR, Cook JD · Annals of the New York Academy of Sciences · 1980
Food iron is absorbed by the intestinal mucosa from two separate pools of heme and nonheme iron. Heme iron, derived from hemoglobin and myoglobin, is well absorbed and relatively little affected by other foods eaten in the same meal. On the other hand, the absorption of nonheme iron, the major dietary pool, is greatly influenced by meal composition. Ascorbic acid is a powerful enhancer of nonheme iron absorption and can reverse the inhibiting effect of such substances as tea and calcium/phosphate. Its influence may be less pronounced in meals of high iron availability--those containing meat, fish, or poultry. The enhancement of iron absorption from vegetable meals is directly proportional to the quantity of ascorbic acid present. The absorption of soluble inorganic iron added to a meal increases in parallel with the absorption of nonheme iron, but ascorbic acid has a much smaller effect on insoluble iron compounds, such as ferric oxide or ferric hydroxide, which are common food contami
