Iron 14mg — Ferrous Fumarate, 90 Tablets

Iron is essential for forming haemoglobin, the protein in red blood cells that carries oxygen around the body. EFSA-recognised contributions include normal energy-yielding metabolism, the reduction of tiredness and fatigue, normal red blood cell and haemoglobin formation, normal oxygen transport, normal cognitive function, normal immune function, and a role in cell division.

Women of menstruating age, vegetarians and vegans, endurance athletes, and people diagnosed with low iron levels are the most common groups who benefit. If you suspect you have iron deficiency, ask your GP for a ferritin blood test before supplementing — taking iron when you don't need it can be harmful.

All three are forms of supplemental iron. Ferrous sulfate is the most common but tends to cause more digestive side effects. Ferrous fumarate (this product) is well-absorbed and gentler on the stomach. Ferrous bisglycinate is the gentlest form but typically more expensive. NHS guidance recommends ferrous fumarate or ferrous sulfate as first-line treatment.

On an empty stomach for best absorption — first thing in the morning or before bed. If iron causes stomach upset, take with food. Pair with a source of Vitamin C to improve absorption, and avoid tea, coffee, dairy, calcium and antacids around the same time.

Vitamin C significantly increases the body's ability to absorb non-haem iron (the form found in plants and supplements). Taking iron with a glass of orange juice, kiwi, or a Vitamin C supplement can meaningfully improve how much iron actually reaches your bloodstream.

Most people notice changes in energy and reduced tiredness within four to eight weeks of consistent daily use. Full restoration of iron stores can take three months or more, particularly if levels were significantly low to begin with.

Iron supplements are well-known for causing constipation, nausea, or dark stools in some people. Taking iron with food, drinking plenty of water, and choosing a gentler form like ferrous fumarate help reduce these effects.

Yes — at the recommended daily dose, ferrous fumarate 14mg is suitable for daily long-term use in those who need it. If you're unsure whether you need iron supplementation, get a ferritin blood test through your GP first.

Yes. Our Iron 14mg is fully vegan, GMO-free, and made in the UK. Ferrous fumarate is a synthetic mineral salt, not animal-derived.

Iron pairs particularly well with our Vitamin B Complex (especially B12 — both are involved in red blood cell formation) and Marine Collagen + Vitamin C (Vitamin C improves iron absorption). Avoid taking iron at the same time as Magnesium Complex or Calcium-based supplements, as they compete for absorption — space them at least four hours apart.
