Is Iron Bisglycinate Supplement Right for You?

 

Iron is one of the most important minerals your body needs, yet iron deficiency remains the most common nutritional deficiency in the UK. Fatigue, pale skin, difficulty concentrating — these are all signs your iron levels may be lower than they should be. Iron bisglycinate supplement offers a gentler, well-absorbed alternative to traditional iron tablets, making it a popular choice for people who struggle with the digestive side effects of standard iron preparations. Natures Aid Iron Bisglycinate Elemental 14mg provides 14mg of elemental iron per tablet across a 90-tablet pack, available from our vitamins and supplements range at Cured Pharmacy for just £9.95.

Iron plays a central role in the formation of haemoglobin — the protein in red blood cells that carries oxygen around your body. Without adequate iron, your body simply cannot produce enough healthy red blood cells, which is why low iron levels can leave you feeling exhausted and breathless even after minimal exertion.

 

How Does Natures Aid Iron Bisglycinate Work?

 

Unlike standard iron salts such as ferrous sulphate, iron bisglycinate is a chelated form of iron. Chelation means the iron molecule is chemically bound to two glycine amino acids, forming a stable complex that resists interference from other dietary compounds. Here is how it works step by step:

  • The chelated iron passes through the stomach largely intact, protected from inhibitors like phytates and tannins found in food and tea.
  • It is absorbed via a different intestinal pathway to non-chelated iron, which reduces competition with other minerals and improves uptake.
  • Once absorbed, the iron is released into the bloodstream and transported to tissues where it is needed — primarily the bone marrow for red blood cell production.
  • Replenished iron stores support normal energy metabolism, immune function, and cognitive performance.

Because less unabsorbed iron remains in the gut, bisglycinate forms are associated with fewer gastrointestinal complaints than higher-dose ferrous salts.

 

Who Should Consider Using This Iron Supplement?

 

This supplement is suitable for adults who have been advised to maintain or support their iron intake, or who experience symptoms consistent with low iron levels. It is particularly well suited to:

  • Women of childbearing age, who lose iron through menstruation each month
  • Vegetarians and vegans, whose diets may be lower in haem iron (the form found in meat)
  • People who have previously experienced digestive discomfort with standard iron tablets
  • Those with increased iron requirements, such as during pregnancy (always consult your GP first)

If you suspect you have iron deficiency anaemia, it is important to get a blood test from your GP to confirm this before starting supplementation. Iron deficiency can sometimes indicate an underlying condition that needs investigation.

Is This Supplement Suitable for Vegetarians and How Should It Be Stored?

 

Natures Aid Iron Bisglycinate 14mg tablets are suitable for vegetarians and vegans, making this iron bisglycinate supplement a practical option for those following plant-based diets who may find it harder to meet their iron needs through food alone. Store the tablets below 25°C in a dry place, away from direct sunlight and moisture. Keep the pack tightly closed and out of reach of children at all times. If you are looking for other health products to support your wellbeing, you can also explore our women's health range for additional support options.

What Is Natures Aid Iron Bisglycinate and What Is It Used For?

 

Natures Aid Iron Bisglycinate Elemental 14mg is a food supplement providing chelated iron in a form designed to be gentle on the digestive system. Each tablet delivers 14mg of elemental iron — 100% of the EU Nutrient Reference Value (NRV) for iron. It is used to help maintain normal iron levels in adults, particularly those at risk of low dietary iron intake. Iron contributes to normal red blood cell formation, normal oxygen transport in the body, normal energy-yielding metabolism, and the reduction of tiredness and fatigue, as recognised by the European Food Safety Authority (EFSA).

This product is not a licensed medicine and is not intended to diagnose, treat, or cure iron deficiency anaemia. If you suspect anaemia, please see your GP for a blood test and appropriate treatment.

 

What Do You Need to Know Before Using Natures Aid Iron Bisglycinate?

 

Before starting any iron supplement, it is worth checking whether it is appropriate for you. Do not take this supplement if any of the following apply:

  • You have haemochromatosis (iron overload disorder) or another condition causing excess iron storage
  • You have been told by a doctor that you should not take iron supplements
  • You are under 18 years of age (unless directed by a healthcare professional)
  • You are allergic to any of the ingredients listed on the product label

Iron supplements can interact with several medicines and nutrients. Be aware of the following potential interactions:

  • Antacids and proton pump inhibitors — may reduce iron absorption; take iron at least 2 hours apart
  • Tetracycline and quinolone antibiotics — iron can reduce the absorption of these antibiotics; separate doses by at least 2–3 hours
  • Levothyroxine (thyroid medication) — iron may reduce levothyroxine absorption; take at least 4 hours apart
  • Calcium supplements — calcium can inhibit iron absorption when taken simultaneously
  • Vitamin C — taking iron alongside vitamin C can enhance absorption

 

How Should You Use Natures Aid Iron Bisglycinate?

 

  1. Take one tablet daily, unless otherwise directed by a healthcare professional.
  2. Swallow the tablet whole with a full glass of water.
  3. You may take it with or without food — taking it with food can help reduce any mild stomach discomfort.
  4. Avoid taking it at the same time as tea, coffee, dairy products, or other supplements that may interfere with absorption.
  5. Do not exceed the recommended daily dose.
Indication Age Group Dose Frequency
Dietary iron support Adults (18+) 1 tablet (14mg elemental iron) Once daily
Not recommended Under 18 Consult a GP

 

What Are the Possible Side Effects of Natures Aid Iron Bisglycinate?

 

Iron bisglycinate is generally considered to be one of the better-tolerated forms of iron supplementation. That said, some people may still experience mild side effects, particularly when first starting the supplement. If you are also managing other health concerns, you might find it helpful to browse our IBS and cramps range for additional digestive support products.

Common side effects (may affect some users):

  • Dark or black stools — this is harmless and expected with iron supplementation
  • Mild nausea, particularly if taken on an empty stomach
  • Constipation
  • Stomach discomfort or bloating

Less common side effects (affect fewer users):

  • Diarrhoea
  • Heartburn or indigestion
  • Metallic taste in the mouth

If you experience severe abdominal pain, vomiting, or any signs of an allergic reaction (such as rash, swelling, or difficulty breathing), stop taking the supplement and seek medical advice immediately.

 

How Should You Store Natures Aid Iron Bisglycinate?

 

  • Store below 25°C in a cool, dry place away from direct sunlight

How does iron bisglycinate work in the body?

Iron bisglycinate is a chelated form of iron where the iron atom is bound to two glycine amino acids, forming a stable complex that resists interference from dietary inhibitors like phytates and tannins. This chelation allows the iron to be absorbed via amino acid transport pathways in the small intestine, improving uptake compared to non-chelated iron salts. Once absorbed, iron is used to produce haemoglobin, which carries oxygen in red blood cells throughout the body.

How do I take Natures Aid Iron Bisglycinate step by step?

Take one tablet daily with a full glass of water, with or without food. Avoid taking it alongside tea, coffee, dairy, or calcium supplements, as these can reduce iron absorption. If you experience stomach discomfort, try taking the tablet with a small meal.

What is the best time of day to take an iron bisglycinate supplement?

Many people find taking iron in the morning works well, as it can be paired with a vitamin C-rich drink like orange juice to enhance absorption. However, if morning doses cause nausea, taking it with lunch or dinner is perfectly acceptable. Consistency matters most — try to take it at the same time each day.

What are the side effects of iron bisglycinate and how do I manage them?

The most common side effects include dark stools, mild nausea, and constipation — all of which are generally less severe with bisglycinate forms than with ferrous sulphate. Taking the tablet with food and staying well hydrated can help minimise digestive discomfort. If side effects persist or worsen, speak to your pharmacist or GP.

Who is eligible to take Natures Aid Iron Bisglycinate 14mg?

This supplement is suitable for adults aged 18 and over, including vegetarians and vegans. It is particularly useful for women of childbearing age, people with low dietary iron intake, and those who have previously experienced digestive side effects with standard iron tablets. It is not recommended for children unless directed by a healthcare professional.

Is iron bisglycinate suitable for vegans?

Yes, Natures Aid Iron Bisglycinate 14mg tablets are suitable for both vegetarians and vegans. This makes them a practical choice for those following plant-based diets, who may have a higher risk of low iron intake due to the absence of haem iron from meat. Always check the product label to confirm ingredient suitability.

What happens if I miss a dose of Natures Aid Iron Bisglycinate?

If you forget to take your tablet, simply take it as soon as you remember — unless it is nearly time for your next dose, in which case skip the missed dose entirely. Never take a double dose to make up for a missed one. Consistent daily use over several weeks is what builds up your iron stores effectively.

What is the difference between iron bisglycinate and ferrous sulphate?

Iron bisglycinate is a chelated form of iron that provides a lower elemental iron dose (14mg) but is absorbed more efficiently and causes fewer gastrointestinal side effects than ferrous sulphate, which typically provides 65mg elemental iron per tablet. Ferrous sulphate is commonly prescribed on the NHS for confirmed iron deficiency anaemia, while iron bisglycinate is widely used as an OTC supplement for dietary support. If you have been diagnosed with anaemia, always follow your GP's treatment recommendations.

Can I take iron bisglycinate during pregnancy?

Iron requirements increase significantly during pregnancy, and many pregnant women are advised to take an iron supplement. However, you should always consult your GP or midwife before starting any iron supplement during pregnancy, as they will assess your blood levels and recommend the most appropriate dose and form for your individual needs.

How long does it take for iron supplements to start working?

According to the NHS, you may start to feel better within 2 to 3 weeks of taking iron supplements regularly, though it can take 3 to 6 months to fully replenish your iron stores. It is important to continue taking the supplement for the full recommended period even if you begin to feel better sooner. A follow-up blood test from your GP can confirm whether your levels have returned to normal.

How long can you take Natures Aid Iron Bisglycinate for?

For general dietary support, this supplement can be taken long term as part of a balanced diet, particularly if you have ongoing risk factors for low iron intake such as a vegan diet or heavy periods. If you are taking it to address a confirmed deficiency, your GP will advise on the appropriate duration. Regular blood tests are recommended to monitor your iron levels over time.

Does iron bisglycinate interact with any medicines?

Yes, iron can interact with several medicines. It may reduce the absorption of tetracycline and quinolone antibiotics, levothyroxine, and some antacids. To minimise interactions, take iron at least 2 hours apart from antibiotics and antacids, and at least 4 hours apart from levothyroxine. Always inform your pharmacist or GP about all supplements you are taking. You can also explore our women's health range if you are managing related health concerns.

What are the alternatives to iron bisglycinate supplements?

Alternatives include ferrous sulphate, ferrous fumarate, and ferrous gluconate — all of which are available OTC or on prescription and provide higher elemental iron doses. Dietary sources of iron include red meat, lentils, spinach, fortified cereals, and tofu. For those who cannot tolerate oral iron at all, intravenous iron infusions are available via the NHS for confirmed cases of iron deficiency anaemia.

What does the latest research say about iron bisglycinate absorption?

Published clinical studies suggest that iron bisglycinate has comparable or superior bioavailability to ferrous sulphate at lower doses, with a significantly better gastrointestinal tolerability profile. Research published in nutritional science literature indicates that the chelated structure protects iron from inhibitors in the gut, making it particularly useful for individuals with sensitive digestive systems. While research is ongoing, current evidence supports its use as an effective and well-tolerated form of iron supplementation for dietary support.

How Should You Use Natures Aid Iron Bisglycinate?

Using this supplement correctly makes a real difference to how well your body absorbs the iron. Follow these steps each day for the best results:

What Is the Correct Dose of Natures Aid Iron Bisglycinate?

The standard recommended dose for adults is one tablet per day, providing 14mg of elemental iron — equivalent to 100% of the EU Nutrient Reference Value. Do not take more than the recommended daily dose unless specifically advised to do so by a healthcare professional.

When Is the Best Time to Use Natures Aid Iron Bisglycinate?

There is no single "correct" time, but many people find that taking iron in the morning — ideally 30 minutes before breakfast or with a light meal — works well. Morning dosing also makes it easier to remember as part of your daily routine. If morning doses cause stomach discomfort, taking the tablet with lunch or dinner is a perfectly reasonable alternative.

Avoid taking iron within two hours of antacids, and at least four hours before or after levothyroxine if you take thyroid medication. Spacing iron away from other supplements, particularly calcium, helps ensure you get the most from each dose.

How Long Can You Use Natures Aid Iron Bisglycinate For?

For ongoing dietary support — for example, if you follow a vegan diet or have heavy periods — this supplement can be taken long term as part of a balanced lifestyle. If you are using it to address a confirmed iron deficiency, your GP will advise on the appropriate duration, which is typically 3 to 6 months. It is a good idea to have your iron levels checked periodically via a blood test to ensure supplementation remains appropriate for you.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Natures Aid Iron Bisglycinate?

Iron bisglycinate is widely regarded as one of the gentler forms of iron supplementation, but some people do experience mild side effects, especially in the first few days of use. These are usually temporary and tend to settle as your body adjusts.

  • Dark or black stools — harmless and expected; caused by unabsorbed iron passing through the gut
  • Mild nausea, particularly if taken on an empty stomach
  • Constipation
  • Stomach discomfort or bloating

What Are the Less Common Side Effects of Natures Aid Iron Bisglycinate?

A smaller number of people may experience the following side effects. These are less likely with bisglycinate forms than with higher-dose iron salts, but they are still worth being aware of.

  • Diarrhoea or loose stools
  • Heartburn or indigestion
  • Metallic taste in the mouth
  • Abdominal cramping

What Are the Serious Side Effects of Natures Aid Iron Bisglycinate?

Serious side effects from iron bisglycinate at the recommended dose are rare. However, you should stop taking the supplement and seek immediate medical attention if you experience any signs of an allergic reaction, including skin rash, itching, swelling of the face or throat, or difficulty breathing. Iron overdose is a medical emergency — if a child accidentally ingests tablets, contact NHS 111 or go to A&E immediately.

What Should You Do If You Experience Side Effects?

For mild digestive side effects, try taking the tablet with food rather than on an empty stomach, and ensure you are drinking enough water throughout the day. If constipation is a concern, increasing your dietary fibre and fluid intake may help. If side effects are persistent, troublesome, or worsening, stop taking the supplement and speak to your pharmacist or GP for advice on whether to continue or switch to an alternative form of iron.

Can Natures Aid Iron Bisglycinate Interact With Other Medicines?

Yes. Iron can affect the absorption of several medicines, and other substances can affect how well iron is absorbed. Key interactions to be aware of include tetracycline and quinolone antibiotics (separate doses by at least 2–3 hours), levothyroxine (separate by at least 4 hours), antacids and proton pump inhibitors (take iron at least 2 hours apart), and calcium supplements (avoid taking simultaneously). Vitamin C taken alongside iron can enhance its absorption. Always inform your pharmacist or GP about all supplements and medicines you are taking before starting a new product.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
