Iron (Ferrous Ascorbate) contains ferrous ascorbate, a chelated form of iron in which ferrous iron is complexed with ascorbic acid (vitamin C). It is used in the prevention and treatment of iron deficiency and iron deficiency anaemia. The ascorbate component maintains iron in its reduced ferrous state, enhancing intestinal absorption and reducing the gastrointestinal side effects associated with conventional iron salts. Always use Iron (Ferrous Ascorbate) exactly as directed by your doctor.

Iron (Ferrous Ascorbate) contains ferrous ascorbate, a stable chelated iron compound combining ferrous iron with ascorbic acid in a single molecular complex. This formulation is designed to address the two principal limitations of conventional iron supplementation, namely poor absorption and gastrointestinal intolerance.

Iron is an essential mineral required for haemoglobin synthesis, myoglobin production, oxygen transport, and numerous enzymatic processes involved in energy metabolism and immune function. Iron deficiency is the most common nutritional deficiency worldwide and leads to microcytic hypochromic anaemia when severe.

In ferrous ascorbate, ascorbic acid serves a dual function. First, it maintains iron in the ferrous (Fe2+) state, which is the form absorbed by intestinal enterocytes via the divalent metal transporter DMT-1. Ferric iron (Fe3+) must first be reduced to ferrous iron before absorption, a step that is bypassed in this formulation. Second, ascorbic acid chelates iron, forming a soluble complex that remains stable in the alkaline environment of the small intestine, further enhancing absorption compared to conventional ferrous salts.

This results in superior bioavailability, faster haemoglobin repletion, and improved gastrointestinal tolerability, making ferrous ascorbate particularly suitable for patients who experience intolerance to standard iron preparations.

The uses of Iron (Ferrous Ascorbate) are as follows:

Iron Deficiency Anaemia

Iron (Ferrous Ascorbate) is used to treat anaemia caused by insufficient iron stores, restoring haemoglobin levels and red blood cell production.

Iron Deficiency without Anaemia

It is used to replenish depleted iron stores before frank anaemia develops.

Anaemia of Pregnancy

It is commonly prescribed during pregnancy to meet increased maternal and foetal iron requirements and prevent gestational anaemia.

Post-Surgical or Post-Haemorrhagic Iron Repletion

It supports iron repletion following significant blood loss from surgery, trauma, or gastrointestinal bleeding.

Nutritional Iron Deficiency

It is used in individuals with inadequate dietary iron intake including vegetarians, vegans, and those with restricted diets.

Here are the benefits of Iron (Ferrous Ascorbate):

• Enhanced Iron Absorption: The chelated ferrous ascorbate complex bypasses the reduction step required by conventional iron salts, improving bioavailability.

• Improved Gastrointestinal Tolerability: The chelated formulation reduces direct mucosal irritation, lowering the incidence of nausea, constipation, and stomach discomfort compared to standard iron preparations.

• Stable in Intestinal Environment: The ascorbate chelation maintains iron solubility in the alkaline small intestinal environment, ensuring consistent absorption.

• Faster Haemoglobin Repletion: Superior absorption translates to more efficient correction of haemoglobin levels and iron stores.

• Combined Iron and Vitamin C: Ascorbic acid contributes antioxidant activity alongside its absorption-enhancing role.

Like all medicines, Iron (Ferrous Ascorbate) may cause side effects in some individuals.

Common Side Effects

• Nausea: Mild gastrointestinal discomfort may occur, particularly when taken on an empty stomach.

• Constipation: Iron supplementation commonly causes constipation due to reduced intestinal motility.

• Dark Stools: Harmless darkening of stools is expected during iron therapy and does not indicate bleeding.

• Stomach Discomfort: Mild abdominal cramping or bloating may occur.

Uncommon Side Effects

• Diarrhoea: Some individuals may experience loose stools, particularly at higher doses.

• Metallic Taste: A mild metallic taste may be reported by some patients.

• Heartburn: Mild acid reflux may occur in sensitive individuals.

Serious Side Effects (Require Immediate Medical Attention)

• Iron Overload: Excessive iron accumulation may cause organ damage; symptoms include fatigue, joint pain, and abdominal discomfort.

• Severe Allergic Reaction: Swelling of the face, lips, or throat with difficulty breathing requires urgent medical care.

• Black Tarry Stools with Abdominal Pain: While dark stools are expected, black tarry stools accompanied by pain may indicate gastrointestinal bleeding and require prompt evaluation.

Always consult your doctor if side effects persist or worsen.

To ensure safe use:

• Use exactly as prescribed by your doctor.

• Preferably taken on an empty stomach for optimal absorption, unless gastrointestinal discomfort occurs, in which case take with food.

• Take at the same time each day for consistent benefit.

• Swallow tablets whole unless otherwise instructed.

• Do not crush or chew modified-release formulations.

Iron (Ferrous Ascorbate) replenishes iron stores through enhanced intestinal absorption facilitated by the ferrous ascorbate complex.

Iron is absorbed in the duodenum and proximal jejunum via the divalent metal transporter DMT-1, which specifically transports ferrous iron (Fe2+). Conventional iron salts contain ferric iron (Fe3+) which must first be reduced by intestinal ferrireductase enzymes before absorption, a process that is inefficient in many individuals, particularly those with reduced gastric acidity.

In ferrous ascorbate, ascorbic acid maintains iron in the ferrous state and forms a chelate that remains soluble in the neutral to alkaline environment of the small intestine. This dual action ensures iron arrives at the absorption site in the correct oxidation state and in a soluble form, significantly improving uptake efficiency.

Once absorbed, iron is transported bound to transferrin in the bloodstream to the bone marrow, where it is incorporated into haemoglobin in developing erythrocytes, and to storage sites as ferritin and haemosiderin.

A few practical measures can help improve treatment outcomes and ensure safe use of Iron (Ferrous Ascorbate):

• Take on an empty stomach where possible: Absorption is significantly higher when taken 30 minutes before meals. If nausea occurs, taking with a small meal is an acceptable compromise.

• Avoid tea, coffee, and dairy near dose time: Tannins in tea, polyphenols in coffee, and calcium in dairy significantly inhibit iron absorption when consumed simultaneously.

Do not take with antacids or calcium supplements: These reduce iron absorption and should be separated by at least two hours.

• Dark stools are expected: Inform patients that darkening of stools is a harmless expected effect of iron therapy and not a cause for concern.

• Complete the full prescribed course: Iron stores take several months to fully replenish even after haemoglobin normalises; do not stop treatment early without medical advice.

Proper storage is important to maintain the stability and effectiveness of Iron (Ferrous Ascorbate):

• Store at room temperature: Keep away from heat, moisture, and direct sunlight.

• Keep in original packaging: Protects the iron complex from oxidation and humidity.

• Keep out of reach of children: Iron overdose in young children can be fatal; store securely at all times.

• Check expiry before use: Do not use after the expiry date printed on the packaging.

Iron (Ferrous Ascorbate) may be affected by certain foods and beverages. However:

• Avoid tea and coffee near dose time: Tannins and polyphenols inhibit iron absorption and should be avoided for at least one hour before and after taking the medicine.

• Avoid dairy products near dose time: Calcium in milk and dairy products competes with iron for absorption via DMT-1.

• Avoid high-phytate foods simultaneously: Wholegrains, legumes, and certain cereals contain phytates that bind iron and reduce its absorption.

• Vitamin C-rich foods may further enhance absorption: Consuming dietary sources of vitamin C alongside this formulation may provide modest additional absorption benefit.

Iron (Ferrous Ascorbate) may interact with the following medicines:

• Antacids and Proton Pump Inhibitors: Reduce gastric acidity, impairing ferrous iron absorption. Separate doses by at least two hours.

• Calcium Supplements: Compete with iron for intestinal absorption via DMT-1; separate by at least two hours.

• Tetracycline and Fluoroquinolone Antibiotics: Iron chelates these antibiotics, reducing their absorption and effectiveness. Separate doses by at least two to three hours.

• Levothyroxine: Iron reduces levothyroxine absorption; doses should be separated by at least four hours.

• Levodopa and Methyldopa: Iron may reduce the absorption of these medicines through chelation.

Iron (Ferrous Ascorbate) should be used carefully in the following conditions:

• Haemochromatosis: Iron supplementation is contraindicated in hereditary haemochromatosis due to the risk of iron overload and organ damage.

• Haemolytic Anaemia: Iron supplementation may not be appropriate in anaemias not caused by iron deficiency and may worsen iron loading.

• Inflammatory Bowel Disease: Active intestinal inflammation may affect iron absorption and tolerability of oral iron preparations.

• G6PD Deficiency: High-dose ascorbic acid in the formulation may cause haemolysis in G6PD-deficient patients.

• Peptic Ulcer Disease: Iron may irritate gastric mucosa; use with caution in active peptic ulcer disease.

Dose depends on the severity of iron deficiency and the clinical indication. Usually taken once or twice daily as directed by your doctor.

If a dose is missed, take it as soon as remembered. Do not double the dose to make up for a missed one.
