Women experience menstrual blood loss every month due to physiological reasons. Blood is essential for women's health, and there is a saying that "men need to tonify the kidneys, while women need to tonify the blood." It is evident that women with good blood circulation have better immunity and complexion. On average, a woman will lose about 30-50 milliliters of blood during menstruation each month.

Many women experience symptoms of anemia because they fail to replenish their blood and continuously lose blood. 

Symptoms of anemia usually include pale complexion, dizziness, fatigue, and sleep disturbances, causing a series of neurological and psychological effects. Severe anemia should be diagnosed and treated in a hospital as soon as possible.

However, for mild symptoms and women who pay attention to daily conditioning, blood can be supplemented through dietary adjustments. The most effective way to replenish blood is to supplement iron because it is the basic element for producing hemoglobin. Iron can be obtained from food or specialized supplements. There are approximately five ways to do this:

1) Eating foods rich in iron, such as animal liver, lean meat, and animal blood. However, excessive intake of these foods can have negative effects, such as high levels of fats and cholesterol. Therefore, it is important to consume them in moderation.

2) Choosing iron-fortified foods, such as iron-fortified soy milk powder and flour. These are suitable for pregnant and lactating women, as well as individuals who need to supplement iron and blood.

It is convenient to incorporate iron-fortified foods or take iron supplements to replenish blood.

3) Taking oral iron preparations. Oral iron preparations are more suitable for treating severe iron deficiency. It should be noted that iron supplements should only be taken when dietary intake is insufficient and under the guidance of a doctor, to avoid excessive iron leading to cellular damage.

4) Supplementing with vitamin C to promote iron absorption. Eating fresh fruits and vegetables rich in vitamin C can enhance the digestion and absorption of iron from food.

5) Avoiding foods that affect iron absorption. It is necessary to avoid drinking strong tea, coffee, and cocoa as the tannic acid in tea and polyphenols in coffee and cocoa can interfere with the body's absorption of iron. Additionally, foods containing oxalates and phytates should also be consumed in moderation as they can affect iron absorption.
