Ferrous Bisglycinate vs Sulfate: Which Iron is Best?

Iron deficiency, a condition often assessed using serum ferritin levels, affects a significant portion of the global population, leading many healthcare providers, including those at organizations like the Mayo Clinic, to recommend iron supplementation. Ferrous sulfate, a common and inexpensive iron salt, frequently causes gastrointestinal side effects that can limit its tolerability and effectiveness, as reported in studies published in journals like The American Journal of Clinical Nutrition. Ferrous bisglycinate chelate, a more bioavailable form of iron, is often considered a gentler alternative, prompting a crucial question for individuals experiencing iron deficiency and healthcare professionals alike: considering both efficacy and tolerability, the central comparison is between ferrous bisglycinate chelate vs ferrous sulfate, and understanding their differences can significantly impact treatment outcomes. The effectiveness of each can be measured using tools such as hemoglobin tests to determine which supplement results in better iron absorption and utilization.

Understanding Iron Supplementation: A Guide to Informed Choices

Iron, denoted as Fe on the periodic table, is an essential mineral that plays a crucial role in numerous bodily functions. It is a fundamental building block of hemoglobin, the protein in red blood cells responsible for transporting oxygen from the lungs to all tissues and organs.

The Vital Role of Iron in Human Physiology

Without adequate iron, the body cannot produce sufficient hemoglobin, leading to a cascade of physiological impairments. Iron also contributes to:

• Myoglobin production: A protein that carries oxygen to muscles.
• Enzyme function: Involved in many metabolic processes.
• Immune system support: Crucial for proper immune cell development and function.
• Overall cellular health: Supporting growth and development.

Therefore, maintaining optimal iron levels is paramount for overall health and well-being.

Iron Deficiency Anemia (IDA): A Global Health Concern

One of the most common consequences of insufficient iron intake is Iron Deficiency Anemia (IDA). IDA occurs when the body's iron stores are depleted, resulting in a decrease in red blood cell production and hemoglobin levels.

Symptoms of IDA can vary in severity, ranging from mild fatigue and weakness to more serious complications such as:

• Shortness of breath.
• Chest pain.
• Cognitive impairment.

Certain populations are at higher risk of developing IDA, including:

• Women of reproductive age (due to menstruation and pregnancy).
• Infants and young children (due to rapid growth).
• Individuals with chronic blood loss or malabsorption issues.
• Vegetarians and vegans (due to lower bioavailability of non-heme iron).

Navigating the World of Iron Supplements

Given the prevalence of IDA and the importance of iron for overall health, iron supplementation is often recommended. However, not all iron supplements are created equal. Different forms of iron exist, each with its own unique properties, bioavailability, and potential side effects.

It is vital to understand these differences to make informed decisions about which supplement is best suited to individual needs.

Iron Forms: A Detailed Comparison

Having established the critical role of iron and the importance of supplementation in certain conditions, it's crucial to understand the different forms in which iron is available. Each form has unique characteristics affecting its absorption, efficacy, and potential side effects. This section provides a detailed comparison of common iron supplements, empowering you with the knowledge to make informed decisions.

Ferrous Bisglycinate Chelate: The Gentle Iron

Ferrous bisglycinate chelate is a form of iron where the iron molecule is bound to two glycine molecules, an amino acid. This chelation process creates a protective layer around the iron, preventing it from interacting with other compounds in the digestive tract that can hinder absorption.

Enhanced Bioavailability

One of the primary advantages of ferrous bisglycinate chelate is its enhanced bioavailability. Studies have shown that it is absorbed more efficiently than other common iron forms, such as ferrous sulfate. This means that a higher percentage of the iron consumed actually makes it into the bloodstream.

Reduced Gastrointestinal (GI) Side Effects

Another significant benefit is the reduced incidence of gastrointestinal side effects*. This is due to its neutral electrical charge, which allows it to remain intact during digestion. This reduces irritation to the gut lining. Common side effects of iron supplements, like nausea, constipation, and stomach upset, are less frequently reported with ferrous bisglycinate chelate.

Ferrous Sulfate: The Traditional Choice

Ferrous sulfate is a widely used and readily available form of iron supplement. It has been a mainstay in treating iron deficiency anemia for many years due to its effectiveness and relatively low cost.

Effectiveness in Treating Iron Deficiency

Ferrous sulfate is effective in raising iron levels and improving hemoglobin production. It is a potent form of iron that can quickly address iron deficiency.

Gastrointestinal (GI) Issues

However, ferrous sulfate is often associated with a higher incidence of gastrointestinal side effects. The unchelated iron can interact with the gut lining, leading to irritation, nausea, constipation, and diarrhea. These side effects can be severe enough to cause some individuals to discontinue their supplementation.

Ferrous Fumarate: A Middle Ground

Ferrous fumarate is another common iron salt used in supplements. It contains a higher amount of elemental iron per weight compared to ferrous sulfate.

Effectiveness and Side Effects

In terms of effectiveness, ferrous fumarate is generally considered to be comparable to ferrous sulfate. However, the side effect profile often falls somewhere in between ferrous sulfate and ferrous bisglycinate chelate.

Some individuals may tolerate ferrous fumarate better than ferrous sulfate. Others may still experience GI issues. Individual response can vary based on sensitivity and dosage.

Other Iron Salts

Beyond the commonly discussed forms, there exists a broader category of "iron salts."

Variations and Considerations

This encompasses various compounds such as ferrous gluconate and ferrous chloride. These salts differ slightly in their iron content and bioavailability. However, they generally share similar characteristics and potential side effects to ferrous sulfate, though to varying degrees.

It's important to note that the specific iron salt used in a supplement can influence its overall tolerability and effectiveness.

Non-Heme Iron: Dietary Sources

Non-heme iron is the form of iron found in plant-based foods and fortified foods. It differs from heme iron, which is found in animal products.

Dietary Sources and Absorption

Good sources of non-heme iron include:

• Leafy green vegetables
• Beans and lentils
• Fortified cereals

The absorption of non-heme iron is significantly influenced by other dietary factors. Certain substances, such as vitamin C, can enhance absorption. Inhibitors like phytates (found in grains and legumes) and tannins (found in tea and coffee) can reduce absorption.

Enhancers and Inhibitors

Consuming non-heme iron with vitamin C-rich foods can significantly improve its absorption. Pairing iron-rich plant foods with citrus fruits or other vitamin C sources is a simple yet effective strategy. Conversely, avoiding tea or coffee around mealtimes can minimize the inhibitory effects of tannins.

Bioavailability and Absorption: Key Factors for Iron Supplementation

Having established the critical role of iron and the importance of supplementation in certain conditions, it's crucial to understand the different forms in which iron is available. Each form has unique characteristics affecting its absorption, efficacy, and potential side effects. This section provides a detailed comparison of bioavailability and absorption as key determinants of iron supplement effectiveness.

Bioavailability refers to the extent to which a nutrient, in this case, iron, is absorbed from the gut, enters systemic circulation, and becomes available for use by the body. It's not simply about how much iron a supplement contains, but rather how much of that iron your body can actually utilize.

Understanding Iron Bioavailability

The bioavailability of iron supplements varies significantly depending on the form of iron present. Factors such as solubility, the presence of enhancers or inhibitors, and individual physiological conditions all play a crucial role.

Iron exists in two primary forms: heme iron (found in animal products) and non-heme iron (found in plant-based foods and most supplements). Heme iron is generally more bioavailable than non-heme iron. However, even within non-heme iron supplements, significant differences exist.

Factors Influencing Iron Absorption

Several factors can either enhance or inhibit iron absorption. Understanding these interactions is vital for optimizing supplementation strategies.

• Form of Iron: Ferrous bisglycinate chelate is designed for enhanced absorption. The chelation process protects the iron molecule from binding with other compounds in the gut, increasing its bioavailability compared to forms like ferrous sulfate.

  Ferrous sulfate, while cost-effective, often has lower bioavailability and a higher incidence of gastrointestinal side effects. The iron salt is more prone to interact with dietary inhibitors.

• Dietary Factors: What you eat alongside your iron supplement can dramatically impact absorption.

  • Enhancers: Vitamin C (ascorbic acid) is a potent enhancer of non-heme iron absorption. It reduces ferric iron (Fe3+) to ferrous iron (Fe2+), the form more readily absorbed in the small intestine. Consuming citrus fruits, bell peppers, or other vitamin C-rich foods or supplements can significantly boost iron uptake.
  • Inhibitors: Certain dietary components hinder iron absorption. Phytates (found in grains, legumes, and nuts), polyphenols (in tea, coffee, and red wine), and calcium can bind to iron in the digestive tract, forming insoluble complexes that prevent absorption. It is advisable to avoid consuming these substances simultaneously with iron supplements.

• Individual Physiological Factors:

  • Stomach Acid (Gastric Acid): Stomach acid plays a vital role in dissolving iron and converting it to a more absorbable form. Individuals with low stomach acid (e.g., those taking proton pump inhibitors or with atrophic gastritis) may experience impaired iron absorption.
  • Gut Health: A healthy gut microbiome is essential for optimal nutrient absorption. Conditions like inflammatory bowel disease (IBD) or celiac disease can damage the intestinal lining, reducing iron absorption.

The Role of Chelated Minerals

Chelated minerals, like ferrous bisglycinate chelate, offer improved bioavailability. Chelation involves binding a mineral to an organic molecule, such as an amino acid. This process protects the mineral from reacting with other substances in the digestive tract, enhancing its solubility and absorption.

The glycine molecules in ferrous bisglycinate chelate help shuttle the iron across the intestinal wall, leading to higher absorption rates and reduced side effects.

Impact of Absorption Rate on Efficacy and Side Effects

The rate at which iron is absorbed significantly impacts both its efficacy and the likelihood of side effects.

• Efficacy: A higher absorption rate translates to greater iron availability for red blood cell production and overall health. Supplements with poor bioavailability may require higher doses to achieve the desired therapeutic effect.
• Side Effects: Rapid, uncontrolled iron absorption can overwhelm the digestive system, leading to common side effects such as nausea, constipation, and abdominal pain. Forms like ferrous sulfate, which are absorbed more rapidly, are more likely to cause these issues. Sustained-release formulations and chelated forms can help mitigate these side effects by promoting a more gradual and controlled absorption process.

Efficacy: How Well Does Each Iron Form Treat Iron Deficiency?

Having established the critical role of iron and the importance of supplementation in certain conditions, it's crucial to understand the different forms in which iron is available. Each form has unique characteristics affecting its absorption, efficacy, and potential side effects. We now turn our attention to how effectively these various iron supplements combat iron deficiency and Iron Deficiency Anemia (IDA).

Defining Efficacy in Iron Supplementation

Efficacy, in the context of iron supplements, refers to the capacity of a specific iron formulation to raise iron levels in the body and, consequently, improve hematological parameters. This is typically gauged by assessing the increase in hemoglobin, ferritin, and other iron-related markers following a period of supplementation. A highly efficacious supplement will demonstrate a substantial and sustained improvement in these markers, indicating that the iron is being effectively absorbed and utilized.

Comparative Efficacy of Different Iron Forms

Numerous clinical studies have sought to compare the efficacy of different iron forms. While ferrous sulfate has historically been considered the gold standard due to its high iron content and relatively low cost, emerging evidence suggests that other forms may offer comparable or even superior benefits, particularly in terms of tolerability and absorption.

Ferrous bisglycinate chelate, for instance, has demonstrated promising results in several studies. Its unique chelated structure is believed to enhance bioavailability and reduce the likelihood of gastrointestinal side effects, leading to better patient compliance and, ultimately, improved iron status.

However, interpreting comparative efficacy data requires careful consideration of several factors. These include the dosage of iron administered, the duration of the study, the characteristics of the study population (e.g., severity of iron deficiency, presence of other medical conditions), and the specific outcome measures used.

For example, a meta-analysis published in the American Journal of Clinical Nutrition compared ferrous bisglycinate chelate with ferrous sulfate in pregnant women with iron deficiency anemia. The study found that both forms were effective in raising hemoglobin levels, but ferrous bisglycinate chelate was associated with a significantly lower incidence of gastrointestinal side effects.

Ferritin and Hemoglobin: Key Indicators of Treatment Success

Ferritin: An Indicator of Iron Stores

Ferritin serves as a crucial indicator of the body's iron stores. As the primary iron storage protein, ferritin levels reflect the amount of iron that is readily available for use. Low ferritin levels are often the first sign of iron deficiency, even before anemia develops.

Hemoglobin: An Indicator of Oxygen Transport

Hemoglobin, the iron-containing protein in red blood cells responsible for oxygen transport, is another essential marker of treatment success. A significant increase in hemoglobin levels indicates that the iron supplement is effectively supporting red blood cell production and improving oxygen-carrying capacity.

Monitoring both ferritin and hemoglobin levels provides a comprehensive assessment of iron status and helps healthcare professionals determine the effectiveness of the chosen iron supplement.

The Importance of Regular Blood Tests

Regular blood tests are paramount in monitoring iron levels and evaluating the effectiveness of any iron supplementation regimen. These tests allow healthcare professionals to:

• Establish a baseline: Determine the initial iron status and the severity of the deficiency.

• Track progress: Monitor changes in iron levels over time in response to supplementation.

• Adjust dosage: Make necessary adjustments to the dosage or form of iron based on individual response and tolerance.

• Detect potential problems: Identify potential side effects or complications associated with iron supplementation.

• Ensure treatment success: Confirm that the iron supplement is effectively raising iron levels and resolving the underlying deficiency.

Blood tests, in conjunction with a thorough clinical evaluation, provide the necessary insights to optimize iron supplementation therapy and achieve the desired outcomes.

Side Effects and Tolerability: Minimizing Discomfort

Having established the critical role of iron and the importance of supplementation in certain conditions, it's crucial to understand that iron supplements aren't without their potential downsides. Each form has unique characteristics affecting its absorption, efficacy, and, crucially, potential side effects. We now delve into the landscape of these adverse effects, focusing on how to minimize discomfort and maximize tolerability for a more successful supplementation experience.

Understanding Common Gastrointestinal Side Effects

Iron supplementation, while necessary for many, often comes with a range of gastrointestinal (GI) side effects. These are primarily due to the unabsorbed iron interacting with the gut microbiota and the gastrointestinal lining.

The most frequently reported side effects include:

• Nausea: A feeling of unease in the stomach, often accompanied by a desire to vomit.

• Constipation: Infrequent bowel movements or difficulty passing stools.

• Diarrhea: Loose, watery stools, often occurring more frequently than normal.

Other possible, but less common, side effects include abdominal cramping, bloating, and even vomiting. The severity of these side effects can vary widely depending on the individual, the dose of iron, and the specific form of iron being taken.

Comparing Side Effect Profiles of Different Iron Forms

Not all iron supplements are created equal when it comes to tolerability. The chemical form of iron significantly influences the likelihood and severity of side effects.

• Ferrous Sulfate: Traditionally, ferrous sulfate has been a widely prescribed iron supplement. However, it is also known for its higher incidence of GI side effects. The relatively poor absorption rate of ferrous sulfate means a significant portion of the iron remains unabsorbed in the gut, contributing to digestive discomfort.

• Ferrous Fumarate: Similar to ferrous sulfate, ferrous fumarate can cause a substantial number of GI side effects. It has comparable bioavailability to ferrous sulfate, therefore, leading to similar tolerability issues.

• Ferrous Bisglycinate Chelate: This form of iron is generally considered to be better tolerated than ferrous sulfate. The chelated structure protects the iron from interacting with substances in the gut that inhibit absorption. This results in higher bioavailability and less unabsorbed iron in the GI tract. Studies have shown a significant reduction in GI side effects with ferrous bisglycinate chelate compared to ferrous sulfate.

Strategies for Minimizing Side Effects and Improving Tolerance

Fortunately, several strategies can help minimize the unpleasant side effects of iron supplementation and improve overall tolerability.

• Taking Iron with Food: While iron is best absorbed on an empty stomach, taking it with food can significantly reduce nausea and other GI discomforts. However, it's essential to be mindful of the type of food consumed. Certain foods and drinks, like dairy products, coffee, and tea, can inhibit iron absorption.

• Starting with a Lower Dose: Begin with a lower dose of iron and gradually increase it as tolerated. This allows the body to adjust and minimizes the shock to the digestive system. This should be done in consultation with a healthcare professional.

• Using Slow-Release Formulations: Slow-release iron supplements release iron gradually over time. This can reduce the concentration of iron in the gut at any given moment, thereby lowering the risk of side effects.

• Dividing the Dose: Instead of taking the entire daily dose at once, dividing it into smaller doses throughout the day can also improve tolerability.

• Choose The Best Iron Supplement: Prioritize iron supplements that are known for their tolerability. Ferrous bisglycinate chelate should be considered as a first choice.

• Consider Probiotics: Probiotics may help improve gut health and reduce GI side effects associated with iron supplementation. Further research is needed, but some studies suggest a beneficial effect.

• Stay Hydrated: Drink plenty of water to help prevent constipation.

• Consult Your Doctor: Discuss any persistent or severe side effects with your doctor. They may be able to adjust your dose, switch you to a different form of iron, or recommend other strategies to manage your symptoms.

The Impact of Side Effects on Patient Compliance

The occurrence of side effects significantly impacts patient compliance with iron supplementation therapy. When individuals experience uncomfortable GI symptoms, they are more likely to skip doses, stop taking the supplement altogether, or seek alternative treatments.

Poor compliance can undermine the effectiveness of iron supplementation and prolong the treatment of iron deficiency. It's crucial to address side effects proactively and find strategies that allow individuals to adhere to their prescribed iron regimen.

Choosing a well-tolerated form of iron, such as ferrous bisglycinate chelate, and implementing strategies to minimize side effects are vital for ensuring successful iron supplementation therapy and improving patient outcomes. Ultimately, prioritizing tolerability can lead to better adherence, more effective treatment, and improved overall health.

Iron Needs in Special Populations and Specific Conditions

Having established the critical role of iron and the importance of supplementation in certain conditions, it's crucial to understand that iron supplements aren't without their potential downsides. Each form has unique characteristics affecting its absorption, efficacy, and, crucially, potential side effects. Now, we turn our attention to specific populations and conditions where iron needs are significantly altered, demanding a nuanced understanding of supplementation strategies.

Pregnancy: Meeting the Demands of Fetal Development

Pregnancy represents a period of dramatically increased iron requirements. The growing fetus demands iron for its own development, particularly for the formation of red blood cells and brain development. Simultaneously, the mother's blood volume expands considerably, further increasing the demand for iron to support oxygen transport.

The recommended daily iron intake during pregnancy is significantly higher than for non-pregnant women. Failure to meet these elevated needs can lead to iron deficiency anemia in the mother, increasing the risk of preterm birth, low birth weight, and developmental delays in the child.

Supplementation strategies must be carefully considered. While dietary sources of iron are essential, they are often insufficient to meet the heightened demands of pregnancy. Therefore, iron supplements are commonly prescribed. Ferrous bisglycinate chelate may be a preferred option due to its enhanced bioavailability and reduced risk of gastrointestinal side effects, which are already common during pregnancy.

Menstruation: Addressing Iron Loss in Women of Reproductive Age

Menstruation is a recurring cause of iron loss in women of reproductive age. The amount of iron lost during each menstrual cycle varies considerably depending on the individual and the duration and heaviness of their periods.

Women with heavy menstrual bleeding (menorrhagia) are at particularly high risk of developing iron deficiency anemia. Even women with "normal" periods may struggle to maintain adequate iron stores, especially if their dietary intake of iron is low.

Supplementation can be a valuable tool for women experiencing significant iron loss through menstruation. The choice of supplement should be guided by individual needs, tolerability, and the severity of iron deficiency. It is essential to monitor iron levels regularly to ensure that supplementation is effective and to avoid over-supplementation.

Anemia: Unraveling the Complexities of Iron Deficiency

Anemia is a condition characterized by a reduced number of red blood cells or a decreased concentration of hemoglobin in the blood. While iron deficiency is the most common cause of anemia (Iron Deficiency Anemia – IDA), it's crucial to recognize that anemia can arise from various underlying conditions.

These include chronic diseases, genetic disorders (e.g., thalassemia), vitamin deficiencies (e.g., B12, folate), and blood loss from other sources (e.g., gastrointestinal bleeding).

IDA specifically results from insufficient iron to produce adequate hemoglobin. Diagnosis typically involves blood tests measuring hemoglobin, hematocrit, serum iron, ferritin (a marker of iron stores), and transferrin saturation.

Iron Deficiency: Diagnosis and Management Strategies

Diagnosing iron deficiency involves a comprehensive assessment that includes blood tests and a thorough evaluation of symptoms. Common symptoms of iron deficiency include fatigue, weakness, shortness of breath, pale skin, brittle nails, and headaches.

However, these symptoms can be non-specific, making accurate diagnosis reliant on laboratory findings. Ferritin levels are particularly important in assessing iron stores.

Treatment for iron deficiency typically involves a combination of dietary modifications and iron supplementation. Dietary changes focus on increasing the intake of iron-rich foods, such as red meat, poultry, fish, beans, and fortified cereals.

As stated previously, Iron supplements are often necessary to replenish iron stores more rapidly. The specific form of iron supplement, dosage, and duration of treatment are determined by the severity of the deficiency and individual patient factors.

The Interplay of Inflammation and Iron Regulation

Inflammation plays a complex role in iron regulation. In the setting of chronic inflammation, the body's ability to absorb and utilize iron can be impaired. This is mediated by hepcidin, a hormone that regulates iron absorption and release from storage.

Inflammation increases hepcidin levels, which in turn reduces iron absorption from the gut and traps iron within cells, limiting its availability for red blood cell production. This can lead to a condition known as anemia of inflammation, also referred to as anemia of chronic disease.

In these cases, traditional iron supplementation may be less effective, as the underlying inflammatory process needs to be addressed. Managing the underlying inflammatory condition is crucial for improving iron status and treating anemia. Additional strategies, such as erythropoiesis-stimulating agents (ESAs) may be considered in certain clinical scenarios.

Regulatory Guidelines and Recommendations for Iron Supplementation

Having established the critical role of iron and the importance of supplementation in certain conditions, it's crucial to understand that iron supplements aren't without their regulatory environment. Ensuring the supplements we consume are safe, effective, and properly labeled is paramount, and several organizations play vital roles in this process.

The Role of Global and National Health Organizations

The World Health Organization (WHO) and the National Institutes of Health (NIH) are instrumental in establishing evidence-based guidelines for iron supplementation. These organizations synthesize extensive research to provide recommendations on appropriate dosages, target populations, and strategies for preventing and treating iron deficiency.

The WHO, as a global leader in public health, issues guidelines applicable across diverse populations and healthcare systems. Their recommendations often consider the prevalence of iron deficiency in specific regions and address the unique needs of vulnerable groups, such as pregnant women and children.

The NIH, particularly through its Office of Dietary Supplements (ODS), focuses on the specific context of the United States. The ODS provides detailed information on dietary supplements, including iron, summarizing scientific evidence on their efficacy and safety. These resources help healthcare professionals and consumers make informed decisions.

FDA Regulations for Iron Supplements

In the United States, the Food and Drug Administration (FDA) plays a crucial role in regulating the manufacturing and labeling of iron supplements. While supplements are regulated differently from prescription drugs, the FDA has the authority to ensure that supplements are safe, properly labeled, and manufactured according to quality standards.

Manufacturing Standards and Safety

The FDA establishes Good Manufacturing Practices (GMPs) that supplement manufacturers must adhere to. These GMPs ensure that supplements are produced consistently and meet quality standards. This includes measures to prevent contamination, ensure accurate ingredient identification, and maintain proper record-keeping.

Labeling Requirements

The FDA also mandates specific labeling requirements for iron supplements. These requirements ensure that consumers have access to essential information, including:

• The amount of iron per serving.

• The form of iron used.

• A list of other ingredients.

• Any necessary warnings.

These labeling requirements help consumers understand what they are taking and make informed choices. However, it is important to remember that the FDA does not pre-approve supplements for safety or effectiveness before they are marketed. This places a greater emphasis on consumers and healthcare providers to critically evaluate the available evidence.

Importance of Evidence-Based Recommendations and Professional Consultation

Navigating the world of iron supplements can be complex. Relying on evidence-based recommendations from organizations like the WHO and NIH is essential for safe and effective supplementation. These guidelines are based on rigorous scientific research and are regularly updated to reflect the latest findings.

Consulting with healthcare professionals is equally crucial. A doctor or registered dietitian can assess individual iron needs, consider any underlying medical conditions, and recommend the most appropriate form and dosage of iron. They can also monitor for potential side effects and adjust treatment plans as needed.

Self-treating with iron supplements without professional guidance can be risky. Excessive iron intake can lead to adverse health effects, and it is important to rule out other potential causes of anemia or fatigue. By partnering with healthcare professionals and relying on evidence-based recommendations, individuals can safely and effectively address iron deficiency and optimize their health.

So, there you have it! When it comes to choosing between ferrous bisglycinate chelate vs ferrous sulfate, the winner really depends on your individual needs and how well your body tolerates each form. Chat with your doctor or a registered dietitian to figure out which iron supplement is the best fit for you and your iron levels. Happy supplementing!
