IRON SUPPLEMENTS FOR SENSITIVE STOMACHS
If you suffer from a sensitive stomach it is often a challenge to find iron supplements that do not upset your stomach. It is important to find the right iron supplements and formats that work that provide the best iron absorption for sensitive stomachs.

- The different types of iron supplements you can take
- The benefits of oral iron supplements
- What are liquid iron supplements?
- Why do some iron supplements upset your stomach?

Types of iron supplements
There are several different ways to increase your iron intake through supplementation. Traditionally there is:
- Low dose oral iron – available over the counter
- High dose oral iron – prescription only
- Intravenous infusion – undertaken in hospital whilst being monitored.
The type of iron you are recommended to take will depend on any symptoms you experience, taking into account your diet and/or blood test results. There is not necessarily the same fix for everyone. Low iron is common, with 1 in 4 women having low iron¹
Oral iron supplements
If your blood test results reveal you have low iron often a very high dose of iron will be prescribed orally to quickly balance out your levels. However, this can be quite harsh on your stomach and isn’t always well absorbed, causing some unpleasant side effects.
This results in up to 50% of people stopping taking their prescribed high dose iron supplements². These side effects commonly include:
- Stomach Cramps
- Black Stools
If the dose is lower you are less likely to experience symptoms, yet very low doses may not replenish levels adequately or quickly enough.
It is important to find an iron supplement that works well with sensitive stomachs and releases iron into your body whilst minimising the side effects.
Active Iron is an iron supplement that is clinically proven to increase iron levels by up to 94%³.
Active Iron is gentle on the stomach, helping to avoid gut irritation.
Liquid iron supplements
One option for people with sensitive stomachs is liquid iron supplements. The liquid format is targeted to release iron quickly into your body but often these doses are very low ranging from 2mg – 10mg, however the recommended daily intake is 14mg.
Some of the side effects of taking liquid iron supplements include teeth staining, a horrible metallic taste that’s difficult to overcome, a burning sensation in the oesophagus diarrhoea and nausea.
Unlike liquid iron supplements, Active Iron is designed to target the body’s site of iron absorption where it is best absorbed, while still reducing the likelihood of side effects. That’s why it is one of the best iron supplements for sensitive stomachs.
Why do some iron supplements upset your stomach?
Many iron supplements upset your stomach because they oxidise in the gut and as a result are poorly absorbed (typically just 10% is absorbed).
It is this oxidation and poor absorption that causes gastrointestinal side effects such as nausea and constipation in 8/10 people⁴.
The higher dose of iron in supplements, the more likely symptoms are to present. It is really important to find a high quality supplement that does not cause these side effects and discomfort.
Active Iron offers a great solution to help avoid gut irritation from iron. Unlike other oral iron it’s whey protein formula protects the iron from oxidation allowing for better absorption⁵ of iron sulfate.
How to take iron supplements and not upset your stomach
Often traditional iron supplements come with advice on how to take them in the best way to not upset your stomach.
Taking your iron supplement with fruit juice can help to increase the absorption of iron from the supplements
Taking your iron supplements alongside food and not on an empty stomach will help to reduce some of the negative side effects, making the iron easier to absorb
Usually if you do take supplements on an empty stomach it can really upset your stomach.
Active Iron was created to avoid this need and make it easier to take iron supplements at any time of day.
Iron supplements that are easy on your stomach
Traditionally iron supplements were very harsh on the stomach and caused many stomach complaints which then resulted in lapsed usage.
Sometimes the symptoms of supplementation are worse than those of low iron, so many people choose to avoid the symptoms that come with taking high dose iron and opt to live with low iron levels instead. This can cause fatigue, weakness, breathlessness to name a few.
To mitigate this, liquid iron supplements were introduced and were offered as a better alternative for those with sensitive stomachs and difficulty completing prescription recommendations.
However liquid iron has its own issues and is not as well absorbed. It can have side effects in addition to those commonly found with traditional iron supplements, and it can also stain your teeth, which obviously you want to avoid!
Active Iron was created to solve the issues of oral iron supplements and give users the boost of iron they need whilst helping to avoid the uncomfortable side effects. Active Iron is less likely to cause stomach upset than traditional iron supplements, and delivers the right amount of iron needed.
