Unpacking the "Number 1" Claim: It's More Than Just Sales
While a single product might dominate sales charts, the "number 1" supplement for an individual depends on personal needs, absorption rates, and tolerability. For example, a supplement best for preventing constipation might not be the highest in sales volume. Reputable sources highlight several top contenders, each with distinct advantages.
The Top Contender: Vitabiotics Feroglobin
Owned by Vitabiotics, a leading UK vitamin company, Feroglobin is widely marketed as the UK's number one iron supplement brand. It is available in several forms, including liquid and slow-release capsules designed to be gentle on the stomach. Feroglobin Original Capsules contain iron, zinc, and B vitamins, which together contribute to the normal formation of red blood cells and haemoglobin. Its popularity and brand recognition make it a frequent top choice for consumers seeking a standard, reliable iron boost. The slow-release formula is a significant selling point, designed to minimise the common digestive discomfort associated with some iron supplements.
Other Leading UK Iron Supplements
Beyond Feroglobin, several other products are highly regarded for specific features:
- Active Iron: This supplement is often praised for its high absorption rate and gentleness on the digestive system. Its unique protein formula allows it to be taken on an empty stomach without causing the typical side effects like constipation. This makes it a strong contender for those with sensitive stomachs or specific absorption challenges.
- Floradix Liquid Iron: A popular choice among those who prefer liquid supplements, Floradix is known for its pleasant taste and easily absorbable liquid form. It combines iron with vitamins B2, B6, B12, and C to aid absorption and reduce tiredness. It is suitable for a wide range of individuals, including vegetarians, pregnant women, and children.
- Vitabright Gentle Iron Bisglycinate: Featured by BBC Good Food as the "best iron supplement overall," this product uses the highly absorbable ferrous bisglycinate form. The 'bisglycinate' form is a chelated iron, meaning it is bound to an amino acid, which enhances absorption and reduces stomach upset. This makes it an excellent gentle option.
- Spatone: This 100% natural iron-rich water is packaged in convenient, single-serve sachets. Its natural form makes it very gentle on the stomach, though it has a lower elemental iron content per sachet compared to many tablets. It is often mixed with fruit juice to improve absorption and mask the metallic taste.

Factors to Consider When Choosing an Iron Supplement
When deciding on a supplement, consider these points:
- Elemental Iron: Look beyond the total weight (e.g., 300mg ferrous fumarate) and focus on the elemental iron content, which is the amount your body can actually use. High-strength supplements are often necessary for treating deficiency, while lower-dose options are for maintenance.
- Iron Form: Different forms have different absorption rates and potential for side effects. Ferrous bisglycinate is known for being gentle and highly absorbable. Ferrous fumarate and ferrous sulphate are common, effective, but can cause stomach upset.
- Presence of Vitamin C: Vitamin C significantly increases iron absorption. Many effective supplements, such as Floradix and Active Iron, include it in their formula. Taking iron with orange juice is a common recommendation.
- Form of Supplement: Decide if you prefer tablets, capsules, liquids, sprays, or gummies. Liquids and sprays may be more palatable and easier for those who struggle with swallowing tablets.
- Dietary Needs: Vegetarians and vegans must ensure their supplement is plant-based and suitable for their diet.
- Consult a Professional: Always speak with a GP or healthcare provider before starting an iron supplement, especially if you suspect a deficiency or are pregnant. Iron levels should be checked through blood tests.
The Role of Iron in the Body
Iron is an essential mineral vital for numerous bodily functions. Its most well-known role is in creating haemoglobin, the protein in red blood cells that carries oxygen throughout the body. A deficiency leads to anaemia, which can cause symptoms like extreme tiredness, shortness of breath, and pale skin. Iron also contributes to cognitive function and a healthy immune system.
Conclusion
While Vitabiotics Feroglobin holds the title of the UK's number one iron supplement brand by sales, the best iron supplement for you is a personal choice based on absorption, gentleness, and format preferences. Active Iron offers superior absorption with minimal side effects, Floradix is an excellent liquid option, and Vitabright provides a highly absorbable and gentle chelated tablet. Spatone is ideal for those needing a very gentle, natural dose. Always consult a healthcare professional for a diagnosis and personalised recommendation, as iron deficiency can have serious health implications if left untreated.

How to Enhance Iron Absorption
- Pair your iron supplement with a source of vitamin C, such as a glass of orange juice, as it significantly boosts absorption.
- Avoid taking iron supplements with tea, coffee, milk, or calcium-rich foods, as these can inhibit absorption.
- Take your supplement on an empty stomach for maximum absorption unless your specific product or a healthcare professional advises otherwise.
- Ensure you get adequate dietary iron from sources like red meat, legumes, and dark leafy greens.
- Avoid taking antacids at the same time as your iron supplement, as they interfere with absorption.
Potential Side Effects
Common side effects of standard iron supplements include constipation, diarrhoea, stomach pain, and dark stools. Choosing a gentler or slow-release form can often mitigate these issues.
Long-Term Usage
Iron supplements are typically prescribed for a period of several months to correct a deficiency. Long-term use without medical supervision is not recommended, as excessive iron can be harmful. Regular blood tests should be used to monitor your levels.
Important Note
Iron supplements should always be stored out of sight and reach of children. Iron overdose can be very dangerous for young children.
