Eat more foods rich in iron, such as animal liver, kidney, lean meat, egg yolk, kelp, black sesame, sesame paste, black fungus, soybean, mushroom, brown sugar, rape, celery and so on. And foods with high content in protein, such as meat, fish, milk and beans. The process of food supplement is slow, and it will be better to supplement some commonly used blood and iron supplements, such as oral iron edge tablets containing Ejiao and ferrous lactate. In addition, eating more vegetables and fruits containing vitamin C can promote the absorption of iron and replenish blood. It usually takes two to three months to replenish blood. Only by insisting on iron supplementation can the effect be obvious. I hope my answer is helpful to you.
