According to the World Health Organisation, iron is the nutrient both men and women are most likely to be deficient in worldwide — with vegans, vegetarians, and women and girls of reproductive age being particularly at risk. A landmark UK study published in Frontiers in Nutrition in October 2025 — studying over 33,000 health-conscious British adults — found that anaemia and iron deficiency are common underlying conditions even in health-aware UK adults, with many cases going undetected particularly in women of menstruating age. The study called for a national screening programme for iron deficiency in women — one that currently does not exist. Read our full guide: Low Iron in Women UK →
Important note on tablet format: Iron 4 Complex is a tablet, not a capsule. All tablets require standard excipients — bulking agents and anti-caking agents — for manufacture. These are declared on the product label and are standard practice for any tablet-format supplement. The active ingredient content (Iron, Vitamin C, B12, Folic Acid) is fully declared and unaffected by excipients. Food supplement — not a medicine.
📊 Latest UK Research — October 2025
A major UK-based study published in Frontiers in Nutrition in October 2025 — "Ironically unwell: anaemia and iron deficiency among health-aware adults in the UK" — studied over 33,000 health-conscious British adults and found:
- 6% had anaemia — with iron deficiency identified as the leading cause
- Many cases go undetected — especially in women of menstruating age
- 31.2% global prevalence in females vs 17.5% in males
- The study called for a national UK screening programme for anaemia and iron deficiency in women
- Around a third of women of reproductive age could have low iron — most go undetected

🔬 Why Vitamin C Is Essential With Iron — The Absorption Science
Dietary iron exists in two forms — haem iron (from meat and fish, absorbed at 15–35%) and non-haem iron (from supplements and plant foods, absorbed at only 2–20%). Vitamin C (ascorbic acid) converts non-haem iron into a more bioavailable form in the gut, significantly increasing absorption. Research shows that taking Vitamin C alongside non-haem iron can increase absorption by up to 6-fold. This is an authorised EU/UK health claim: Vitamin C contributes to the increase in iron absorption. The 60mg Vitamin C in each Iron 4 Complex tablet provides this benefit in the same tablet — no additional supplementation required. Educational background — food supplement, not a medicine.

What is in Iron 4 Complex?
Iron 14mg (Ferrous Fumarate, 100% NRV) + Vitamin C 60mg (75% NRV) + Vitamin B12 3mcg (120% NRV) + Folic Acid 200mcg (100% NRV). Standard tablet excipients included as required for tablet manufacture — declared on label. All four nutrients carry authorised EU/UK health claims. Food supplement — not a medicine.
Who is most likely to be low in iron in the UK?
According to the WHO, iron is the nutrient both men and women are most likely to be deficient in — with vegans, vegetarians, and women of reproductive age being particularly at risk. A major UK study in Frontiers in Nutrition (October 2025) of over 33,000 health-conscious adults found iron deficiency is common and largely undetected in UK women of menstruating age. Always consult your GP for a blood test. Read our full guide →
Why is Vitamin C included with iron?
This is an authorised EU/UK health claim: Vitamin C contributes to the increase in iron absorption. Vitamin C converts non-haem iron (the form in supplements and plant foods) into a more bioavailable form in the gut, significantly increasing the proportion absorbed. Research shows absorption can increase by up to 6-fold when Vitamin C is taken alongside non-haem iron. Food supplement — not a medicine.
Why include B12 and Folic Acid with iron?
Both Vitamin B12 and Folic Acid have authorised claims for normal formation of red blood cells and reduction of tiredness and fatigue — complementing iron's role in haemoglobin production. B12 deficiency is also common in vegans and vegetarians. All four nutrients support the same physiological pathway in one daily tablet. Food supplement — not a medicine.
Is this tablet format or capsule?
Tablet. All tablets require standard excipients — bulking agents and anti-caking agents — for manufacture. These are declared on the product label. The active ingredient content is fully declared and unaffected by excipients. For a filler-free capsule supplement, see our range of HPMC capsule products.
Is Iron 4 Complex suitable during pregnancy?
Always consult your GP or midwife before taking any supplement during pregnancy. Folic Acid is particularly important in early pregnancy — 400mcg per day is recommended for the first 12 weeks. This tablet provides 200mcg per tablet. Your GP may recommend a specific pregnancy supplement or prescribed iron. Food supplement — not a medicine.
Can iron supplements cause constipation?
Iron supplements can cause digestive side effects including constipation. Ferrous Fumarate — the iron form in Iron 4 Complex — is generally better tolerated than Ferrous Sulphate at equivalent doses. Taking with food may reduce discomfort. Consult your GP if side effects are significant. Food supplement — not a medicine.
