Disodium Guanosine + Iron (Ferrous Ascorbate) + Lactoferrin is a nutraceutical used to manage iron deficiency and iron deficiency anaemia, including during pregnancy. Ferrous ascorbate supplies iron in a well-absorbed form bound to vitamin C, while lactoferrin (a milk-derived protein that binds iron) helps the body take up iron and counters the inflammation signals that block its absorption. Disodium Guanosine 5-Monophosphate, a nucleotide, helps iron move out of gut cells and into the bloodstream. Together, they aim to raise haemoglobin levels and rebuild iron stores, with fewer stomach-related side effects than traditional iron salts.

Iron deficiency is the most common nutritional deficiency and the leading cause of anaemia worldwide. Standard ferrous sulfate works well but often causes nausea, constipation, and a metallic taste, which makes it hard for many people to stick with treatment. This combination tackles those issues through three complementary actions.

Ferrous Ascorbate binds iron to vitamin C, keeping it in its most absorbable form (Fe²⁺) as it passes through the gut, and is generally easier on the stomach than ferrous sulphate. Lactoferrin, a protein naturally found in human milk and other body secretions, has been shown in randomised trials and meta-analyses to raise serum iron, ferritin, and haemoglobin, partly by lowering the inflammation-driven hepcidin that would otherwise block iron absorption. Disodium Guanosine 5-Monophosphate (a nucleotide) has been reported to lower hepcidin further, keeping ferroportin, the iron "exit door" on gut cells open so iron can pass into the bloodstream. The combination is most often used for anaemia in pregnancy, anaemia linked to chronic disease (where hepcidin is high), and in people who cannot tolerate standard oral iron.

Iron deficiency anaemia

To raise haemoglobin and replenish iron stores.

Iron deficiency without anaemia

To restore ferritin and prevent progression to anaemia.

Anaemia in pregnancy

To meet the increased iron demand of pregnancy.

Postpartum and lactation

To replace iron lost at delivery and support recovery.

Patients intolerant of conventional iron salts

As a better-tolerated alternative.

• Improves the levels of haemoglobin, serum iron, and ferritin in those who've been diagnosed with iron-deficiency.

• Generally, better tolerated gastrointestinally than just ferrous sulfate.

• Lactoferrin's anti-inflammatory action helps where the partial cause of anaemia is inflammation.

• Useful in pregnancy, where high iron demand and gastric sensitivity often coexist.

• Easier to adhere to, as the dosing is once daily.

Common

• Mild nausea or stomach discomfort
• Constipation or, less often, diarrhoea
• Dark or black stools (a normal effect of oral iron)
• Metallic aftertaste

Uncommon

• Loss of appetite
• Cramps in the abdomen
• Heartburn
• Staining of teeth, seen in those who use liquid forms for prolonged periods

Serious side effects requiring immediate attention

• Hypersensitivity, which may manifest as skin rash, swelling, and difficulty
• in breathing, especially in those with milk-protein allergy
• Severe abdominal pain, vomiting, or bloody stools
• Signs of iron overload with long-term unsupervised use

Take orally once daily, preferably on an empty stomach (one hour before or two hours after food) for best absorption, or with a light meal if Disodium Guanosine + Iron (Ferrous Ascorbate) + Lactoferrin causes irritation. Avoid taking Disodium Guanosine + Iron (Ferrous Ascorbate) + Lactoferrin with milk, tea, coffee, antacids, or calcium supplements at the same time, as these reduce iron absorption. Continue for at least three months after haemoglobin normalises to fully replenish stores, or as advised by your doctor.

Iron absorption is controlled by a liver hormone called hepcidin. When your body already has enough iron or when there's inflammation, hepcidin levels go up. Hepcidin then shuts down ferroportin, which is the only door that lets iron pass out of gut cells into the bloodstream. With that door closed, the iron you eat stays stuck inside the gut cells and is lost when those cells are naturally shed a few days later.

While ferrous ascorbate delivers iron in its most absorbable form (Fe²⁺), the vitamin C component keeps it soluble as it moves through the upper gut. Lactoferrin then carries iron in a form that gut cells can absorb through their own lactoferrin receptors. It also calms the inflammation signals that would normally raise hepcidin and block iron absorption.

Disodium Guanosine 5-Monophosphate, a nucleotide, help lower hepcidin levels further, aiding iron to move out of gut cells and into the bloodstream. Together, the three components deliver more iron to the bone marrow with fewer of the stomach-related side effects often seen with high-dose iron salts.

• Tea and coffee (CAUTION): Tannins found in both coffee & tea bind iron and lower its absorption. Separate them by at least 2 hours.

• Milk and dairy (CAUTION): Calcium competes with iron. Take the medicines at a different time.

• Whole grains and legumes (CAUTION): Phytates reduce iron absorption. Stop or limit the consumption.

• Vitamin C-rich foods (BENEFICIAL): Citrus foods rich in vitamin C enhance iron uptake.

• Alcohol (CAUTION): May aggravate gastric irritation and impair folate metabolism. Limit or avoid consumption.

• Levothyroxine (SEVERE): Iron binds to levothyroxine in the gut and reduces its absorption, potentially hampering the treatment of hypothyroidism (low thyroid levels). Separate the medicines by at least 4 hours.

• Tetracyclines and fluoroquinolones (SEVERE): Iron forms insoluble complexes with these antibiotics, reducing their absorption and efficacy. Separate the medicines by 2 to 4 hours.

• Methyldopa, levodopa, and penicillamine (CAUTION): Iron chelates these drugs and lowers their bioavailability, reducing their efficacy. Separate the doses by at least 2 hours.

• Bisphosphonates (CAUTION): Iron reduces bisphosphonate absorption. It is advised to take the bisphosphonate first thing in the morning and the supplement at least 2 hours later.

• Antacids and proton pump inhibitors (CAUTION): Reduce gastric acidity, which impairs the conversion of ferric to ferrous iron and decreases iron absorption. Long-term users may require dose adjustment.

• Cholestyramine (CAUTION): Binds iron in the intestinal lumen and reduces its absorption. Separate doses by several hours.

• Haemochromatosis and iron overload states (CONTRAINDICATED): Extra iron from Disodium Guanosine + Iron (Ferrous Ascorbate) + Lactoferrin worsens systemic iron deposition in the body and increases the risk of hepatic cirrhosis (liver fibrosis), cardiomyopathy (disease of the heart muscle), endocrine dysfunction, and organ damage.

• Thalassaemia and sideroblastic anaemia (AVOID): Increases the risk of transfusional and dietary iron overload. Use only if advised by your doctor.

• Active inflammatory bowel disease (CAUTION): Oral iron may worsen mucosal inflammation. IV (intravenous) iron administration is often recommended for those with moderate-to-severe active disease.

• Peptic ulcer disease and gastritis (CAUTION): Oral formulations of iron supplements are likely to irritate the gastric mucosa and may aggravate chronic indigestion (dyspepsia), epigastric pain (pain in the upper abdomen), or bleeding. To lower the risk, take Disodium Guanosine + Iron (Ferrous Ascorbate) + Lactoferrin with food or consider lower-dose or alternate-day dosing.

• Repeated blood transfusions (CAUTION): Each unit of transfused packed red cells delivers approximately. 200–250 mg of iron, which cannot be excreted from the body. Cumulative transfusional iron load may already be high, raising the risk of secondary haemochromatosis (excessive iron accumulation in the body tissues).

Take the missed dose of Disodium Guanosine + Iron (Ferrous Ascorbate) + Lactoferrin as soon as you remember on the same day. If it is almost time for the next dose, skip it and continue your regular schedule. Do not double up. Consistent use over weeks to months is what restores iron levels.
