Ferrous Fumarate

The Essential Oxygen Carrier

A well-absorbable source of iron that improves energy production, oxygen transport, and cognitive performance.

What is Ferrous Fumarate Good For?

Ferrous Fumarate provides iron in a stable, bioavailable form. Iron is a critical mineral required for haemoglobin formation, oxygen delivery to tissues, and energy metabolism. It also supports immune function, brain performance and promotes growth for children.

 

Ferrous Fumarate supplementation may lead to:

  • Prevention of low iron levels

  • Enhanced energy production and reduction of fatigue

  • Increased oxygen transport for muscles and brain

  • Improvements in attention and concentration

  • Increased immune defence against viruses and pathogens

What is Iron?

Iron is an essential trace mineral that enables red blood cells to transport oxygen throughout the body. Without sufficient iron, cells cannot produce energy efficiently, leading to fatigue, weakness, and poor cognitive function.

 

Ferrous Fumarate is a salt form of iron with high elemental content and good tolerability, making it one of the most widely used supplemental iron forms.

What is the Recommended Daily Dose of Ferrous Fumarate?

A 7 mg dose of elemental iron (as ferrous fumarate) provides 50% of the European Union’s Nutrient Reference Values (EU NRV) for adults. This is sufficient for maintenance in healthy individuals and is often used in formulations where iron is combined with other nutrients.

Ferrous Fumarate is a form of supplemental iron used to maintain and correct iron status, supplying a concentrated dose of elemental iron.
It supports red blood cell production, reduces fatigue, improves cognition, and strengthens immunity.
Compared to ferrous sulfate, ferrous fumarate provides a higher concentration of elemental iron and may be better tolerated by some individuals.
Iron supplements may cause mild digestive upset in some individuals (constipation, dark stools). Taking with food often reduces discomfort. Always follow dosage guidance.
Yes, but iron absorption may be reduced by calcium, caffeine, or phytates (from grains/legumes). Vitamin C enhances absorption and is often paired with iron.
