Is it vitamin E or vitamin C that is good for oral iron absorption?

Vitamin C as a reducing agent and chelating agent can promote the absorption and utilization of iron, and can also reduce trivalent iron to ferric iron, making it easy to dissolve, even if the pH in the small intestine is high, it can still maintain the solubility of iron, so that the absorption rate of iron can be increased by 3 5 times. For example, adding 60 mg of vitamin C to rice can increase the absorption of iron by 3 times, so it is best to take vitamin C at the same time as taking iron supplements. Vitamin C does not have this effect if taken 4 hours before taking iron.

Vitamin C also accelerates the mobilization and release of stored iron and promotes the recycling of iron in hemoglobin. Vitamin C insufficiency can reduce iron absorption, reduce red blood cell iron recycling, and increase hemosiderin content in the liver and spleen. The use of vitamin C in iron toxicity accelerates the excretion of iron from the urine by deferoxamine.

Vitamin C can also promote the conversion of folic acid into tetrahydrofolate and formyltetrahydrofolate, which is beneficial for hematopoiesis.

Vitamin C can promote iron absorption Acidic environments can promote iron absorption Iron supplementation should be supplemented with ferric iron.

Iron supplementation is also necessary to supplement some vitamin C, in the intestine, only ferric iron (Fe2+, reduced iron) can be absorbed, and trivalent iron (Fe3+, oxidized iron) is not absorbed. Vitamin C is highly reducing, allowing iron to remain in an absorbable ferrous state, thereby promoting iron absorption.

There are two forms of iron in food, one is hemoglobin iron and the other is non-hemoglobin iron. The former is ferrous and binds to porphyrin rings in hemoglobin or myoglobin and is easily absorbed in the intestine; The latter is ** iron, which exists in food in the form of ions, and can only be absorbed in the upper part of the duodenum and jejunum through the active absorption process, and is easily affected by factors such as phosphoric acid, phytic acid, oxalic acid, and tannins in food, and the absorption rate is low.

To improve iron absorption, vitamin C is often supplemented at the same time as iron supplementation. This is because vitamin C can convert ** iron into low-valent iron, promote the binding of ferritin on the intestinal mucosa, and directly help the absorption of iron; On the other hand, the environment in the duodenum is alkaline, and there are many hydroxyl groups in the alkaline aqueous solution, which will combine with iron to form iron hydroxide with poor solubility, so it is not easy to be absorbed by the small intestinal mucosa, vitamin C is a reducing agent, which provides hydrogen ions, which can be competitively combined with hydroxyl groups in the duodenum and **iron, so vitamin C also indirectly helps the absorption of iron.

Someone has done such a test, drinking a glass of orange juice containing vitamin C 50-70mg at breakfast can increase the absorption of non-hemoglobin iron in breakfast by 3 times. The amount of vitamin C in each meal is directly proportional to the absorption of iron. In addition, a certain amount of vitamin C can also reduce the inhibitory effect of phytic acid and oxalic acid on iron absorption in food.

Therefore, vitamin C should be supplemented at the same time as iron supplementation.

The absorption of iron in the human body is limited, so vitamin C should be supplemented at the same time, because vitamin C can promote the absorption of iron and promote the formation of tetrahydrofolate. When we eat iron-rich foods such as animal liver and lean meat, it is better to eat them with large vegetables. Mixed fruits and vegetables are rich in vitamin C.

Therefore, people with anemia must also be paired with fresh fruits and vegetables while replenishing meat.

For iron deficiency anemia, if oral iron supplementation is used, it is recommended to take vitamin C and take it orally, because vitamin C can promote iron absorption. Patients with iron deficiency anemia, when the anemia is mild, can be treated with oral iron supplementation plus oral vitamin C**.

If the anemia is severe, red blood cell transfusions are needed to correct the anemia. Intravenous iron supplementation is also recommended because intravenous iron is more bioavailable and has a faster onset of action than oral iron supplementation.

In patients with iron deficiency anemia, if oral iron is added to oral vitamin C, the patient is free of stomach disorders such as ulcers and erosions.

Because vitamin C can help iron to be better absorbed by the mucosa of the gastrointestinal tract after entering the gastrointestinal tract. Better use of the iron supplements.

Because vitamin C can promote the absorption of iron, supplementing with vitamin C at the same time as iron supplementation can better promote the absorption of iron by the body.

Answer] :d 1Vitamin D is often used in combination with calcium for the treatment of rickets.

2.Vitamin <>

For pernicious anemia.

3.Vitamin B <>

It can prevent and treat peripheral nerve symptoms caused by isoniazid.

4.Reducing substances such as vitamin C can convert trivalent iron into bivalent iron, which is conducive to promoting the absorption of iron.

Vitamin C.

Studies have shown that vitamin C can help with iron absorption, and foods rich in vitamin C such as oranges, kiwifruit, and tomatoes can be eaten appropriately. However, vitamin C is very unstable and easy to be oxidized, so do not leave the fruit for too long after cutting to avoid the loss of vitamin C.

It has been found that patients with iron deficiency often have copper deficiency as well. In addition, copper is a component of many hematopoietic-related enzymes, and when copper deficiency occurs, hemoglobin synthesis is hindered due to the decrease in ceruloplasmin, which will also lead to a decrease in iron absorption and utilization, thereby aggravating anemia.

Analysis: Vitamin C

Suggestions: Vitamin C is a reducing agent, which can reduce trimethyl iron to dimethyl iron. Therefore, it is conducive to the absorption of iron, and iron supplementation is generally recommended to take vitamin C orally at the same time

Answer]: There are two benefits to taking vitamin C while taking iron supplements. First, vitamin C can maintain a certain acidity in the small intestine, so that iron is soluble for absorption in the small intestine.

The second is that hemoglobin can only play the function of carrying oxygen after combining with bivalent iron, but after the elimination of a branch of bivalent iron into the human body, it will be converted into trivalent iron, and the antioxidant capacity of vitamin C can prevent this process. For this reason, doctors usually recommend that patients take 25 mg of vitamin C while taking iron.
