Iron(II) fumarate (Cat No.:R027930) is an iron salt of fumaric acid with the molecular formula C4H2FeO4. It appears as a reddish-brown to dark red crystalline powder and is commonly used as an iron supplement to treat or prevent iron-deficiency anemia. Ferrous fumarate provides a high bioavailable source of elemental iron, making it effective in oral formulations such as tablets and capsules. It is generally well tolerated, though gastrointestinal side effects like constipation or nausea may occur. Proper storage in a cool, dry place is recommended to maintain stability and potency.
