Can vitamin C promote iron absorption and should it be taken before or after iron supplementation

2026-05-21

　　Vitamin C and iron are both essential vitamins for human life activities,. Do you know if vitamin C can promote iron absorption and whether it should be taken before or after iron supplementation? Below, the Zhengzhou Shanchen Blue Hat Soft Candy Franchise Editor will share some relevant knowledge with you, hoping to be helpful to you.

　　1. Can vitamin C promote iron absorption

　　This is possible. After being absorbed by the human body, iron agents will be oxidized into stable trivalent iron, which is not conducive to human absorption. Vitamin C is a reducing agent with antioxidant function, which can reduce trivalent iron to easily absorbable divalent iron, thereby promoting the absorption of iron elements. At the same time, vitamin C can also form unstable complexes with iron molecules and release iron from other complexes, thereby promoting the absorption of non iron hemoglobin iron and increasing the body's resistance to diseases.

　　2. Should vitamin C be taken before or after iron supplementation

　　It can be taken together at the same time. Vitamin C and iron supplements have no pharmacological contraindications, and taking a moderate amount of vitamin C while supplementing iron supplements can promote the reduction of trivalent iron, which is more conducive to promoting iron absorption. It is recommended that both be taken together for better results. However, as both drugs have a certain degree of irritation to the gastrointestinal tract, it is recommended to take them between meals or after meals; And avoid taking it with milk.
