Is there an Iron Supplement That Does Not Cause Heartburn?

For some individuals, iron supplements are a potent trigger of heartburn.

This painful condition causes a burning feeling in the middle of the chest or oesphagus and it's a sure sign your stomach isn't too happy.

In this article, I'll explore the link between iron supplements and heartburn, discuss common forms of iron that may cause the issue, and provide tips on how to minimise or even cure the problem.

Why Do Iron Supplements Cause Heartburn and Reflux?

When we take traditional iron supplements, such as ferrous sulfate or fumarate, the iron reacts with the hydrochloric acid (HCl) in our stomach. This reaction can lead to the production of more stomach acid, which can cause irritation and inflammation of the esophagus, resulting in heartburn and reflux symptoms.

In fact, my experience tells me that iron causes more digestive complaints for my clients than any other mainstream supplement. 

For some people, iron supplements also cause a decrease in lower esophageal sphincter (LES) pressure, which is the muscle at the bottom of the esophagus that normally prevents stomach acid from flowing back up into the esophagus. This allows stomach acid to reflux back into the esophagus, causing a lot of discomfort in the process.

But there are still more reasons why iron can be problematic.

Another study shows that another reason why iron supplements may cause heartburn is that they can take longer to digest than other types of supplements. This can cause the iron to sit in the stomach for longer periods, leading to the production of more acid.

As I'll explain below, nano iron offers a highly successful solution to this problem, with it's entirely gentle formula.

Can Iron Aggravate GERD?

Yes, studies show that iron supplementation can aggravate Gastroesophageal Reflux Disease (GERD), which is a form of heartburn where the acid reaches right into the oesphagus. It's known for being particularly painful.

The acidic nature of certain iron supplements increase gastric acid production, exacerbating GERD symptoms by weakening the lower esophageal sphincter (LES).

Bloating and pressure buildup in the stomach, put additional pressure on the LES, causing it to relax further.

Moreover, some iron supplements can slow down the emptying of the stomach, providing more time for acid reflux to occur.

Finally, the interaction between iron and the microbiome could also indirectly affect GERD, as imbalances in gut bacteria may contribute to gastrointestinal symptoms.

Tips to Minimise Heartburn & Acid Reflux from Iron Supplements

There are several tips that may help minimise heartburn when taking iron supplements:

1. Choose Nano Iron for a supplement that doesnt cause heartburn

2. Take iron supplements with food: Food helps to buffer the stomach acid and may prevent irritation of the esophagus.

3. Avoid taking iron supplements with antacids: Antacids can reduce stomach acid, which may affect the absorption of iron supplements. If you need to take an antacid for heartburn, try to wait at least two hours after taking your iron supplement before taking an antacid.

4. Use a lower dose: Taking a lower dose of iron supplement may reduce the risk of heartburn. Speak with your healthcare provider to determine the appropriate dose for you.

5. Drink plenty of water: Drinking water can help dilute stomach acid and may reduce the risk of heartburn.

6. Avoid lying down after taking iron supplements: Lying down after taking iron supplements can increase the risk of heartburn. Try to remain upright for at least 30 minutes after taking your iron supplement.

7. Consider a different form of supplement: Some forms of iron supplements, such as iron bisglycinate or iron polysaccharide, may be less likely to cause heartburn than others. 

What's the Best Iron Supplement for Heartburn or Reflux

Although there are lots of choices out there calling themselves 'gentle iro'n, the science of taking a traditional oral iron supplement inevitably means a rapid increase of free iron in the digestive tract which causes oxidative stress and microbiome disruption. 

Nano Iron, however, is specifically designed to do things different. Nano Iron from The Health Factory has the smallest possible particles between 0.5 and 7 nano metres, in the purest elemental form, which is dissolved in purified water. This means the particles are so tiny it can be absorbed through the oral mucosa (throat tissue) resulting in a complete absence of side effects such as constipation, heartburn, GERD or nausea.

Additionally, it has no fillers, residues, additives, excipients and adulterants as you find in many supplements being made of simply nano particulate elemental iron in purified water.

What Should I do if I'm Taking Iron Supplements but Have Acid Reflux?

If you're experiencing acid reflux while taking iron supplements, the following specific steps are advised:

1. Consult an expert: The first step should always be to consult with a healthcare provider for diagnosis and personalised advice, including potential adjustments to your iron supplementation regimen.

2. Switch to Non-Acidic Forms of Iron: Discuss with your healthcare provider about switching to a non-acidic form of iron, like Nano Iron, which is gentler on the stomach and less likely to exacerbate acid reflux symptoms.

3. Adjust Timing: Taking iron supplements on an empty stomach can increase the likelihood of acid reflux. Try taking them with a meal to buffer the effects on your stomach, but seek advice for tailored advice on timing.

4. Reduce Dosage: A high dosage of iron may irritate the gastrointestinal tract. Discuss with your healthcare provider about possibly lowering the dosage and monitoring symptoms and iron levels accordingly.

5. Co-administer with Antacids: For some, taking antacids alongside iron supplements can mitigate reflux symptoms. However, antacids can also interfere with iron absorption and may have other side effects.

6. Monitor Symptoms and Reevaluate: Frequent monitoring of symptoms, as well as iron and ferritin levels through diagnostic tests, will help in assessing the efficacy of the adjusted treatment approach.

7. Review Other Medications: Sometimes, acid reflux can be exacerbated by other medications you may be taking. Discuss with your healthcare provider about other medications and their potential impact on acid reflux.

8. Lifestyle Changes: Incorporate lifestyle changes such as elevating the head while sleeping and avoiding trigger foods that exacerbate acid reflux.
