Disclosed herein is an application of orally administered iron particle, which is a zero-valent porous nano-scale particle and has a structure of a medium-porosity material. After being orally introduced into the human body, the iron particle can be digested by the gastrointestinal tract to promote the synthesis of ferritin and supply iron to human body organs in need of iron. Furthermore, because the zero-valent iron does not easily stimulate the stomach, this invention can be used as an iron agent for treating and preventing iron deficiency symptoms and iron deficiency anemia and associated symptoms.一種口服鐵粒子之應用,其為一種零價多孔性納米級粒子,且結構為一種中孔洞材料,透過口服進入人體後,經過腸胃道之消化,可促進鐵蛋白之生合成,將鐵供給身體所需的器官,且零價鐵不易刺激胃部,進一步可作為治療、預防鐵缺乏症狀和缺鐵性貧血以及與其有關聯症狀的口服鐵劑。F‧‧‧鐵粒子H‧‧‧孔洞
