成年人体内大约含有4.2 g至6.1 g的铁。其中，大约60%至70%的铁元素存在于红细胞中的血红蛋白里，负责氧气的运输；约4%的铁则分布在肌肉的肌红蛋白中，参与氧气的储存与释放；另有0.2%至1%的铁元素作为细胞色素酶的组成部分，在能量代谢过程中发挥着重要作用。剩余的铁元素则主要以铁蛋白和含铁血黄素的形式，储存在肝脏、肾脏、脾脏以及骨髓的网状内皮系统等组织器官中。铁元素是人体内含量最多且最容易缺乏的微量元素之一，它在人体内发挥着至关重要的生理功能。铁的生理功能主要包括作为血红蛋白和肌红蛋白的重要组成部分，参与氧的运输与储存；作为细胞色素、细胞色素氧化酶、过氧化氢酶等酶的辅基，参与能量代谢；参与免疫细胞的增殖和分化，以及抗体的产生和免疫应答的调节；维持神经系统健康以及促进消化和营养吸收等以及其他生理过程。

铁的吸收与补充是人体维持正常生理功能的重要环节。当人体铁元素缺乏时，可能会导致缺铁性贫血等一系列健康问题。铁补充剂是用于治疗和预防铁缺乏及相关疾病的重要药物，常见的铁补充剂类型包括无机铁剂和有机铁剂，其中无机铁剂如硫酸亚铁可能引起胃肠道不适，如恶心、呕吐、腹痛、腹泻等，而有机铁剂（抗坏血酸铁Iron Ascorbate、甘氨酸铁Iron Glycinate）在提高铁的吸收率和生物利用率的同时通常具有更好的胃肠道耐受性，是铁元素补充剂的理想选择。

The adult body contains about 4.2 g to 6.1 g of iron. Of this iron, about 60% to 70% is found in hemoglobin in red blood cells, which is responsible for the transport of oxygen; about 4% is found in muscle myoglobin, which is involved in the storage and release of oxygen; and 0.2% to 1% is found in cytochrome enzymes, which play an important role in energy metabolism. The remaining iron is stored in tissues and organs such as the liver, kidneys, spleen and the reticuloendothelial system of the bone marrow, mainly in the form of ferritin and ferrohemoglobin. Iron is one of the most abundant and deficient trace elements in the human body, and it plays a crucial physiological function in the human body. Iron's physiological functions include being an important component of hemoglobin and myoglobin, participating in oxygen transport and storage; participating in energy metabolism as a cofactor of cytochrome, cytochrome oxidase, catalase and other enzymes; participating in the proliferation and differentiation of immune cells, as well as the production of antibodies and the regulation of immune response; maintaining the health of the nervous system and promoting digestion and nutrient absorption, as well as other physiological processes.

Iron absorption and supplementation is an important part of the body to maintain normal physiological functions. When the human body is deficient in iron, it may lead to a series of health problems such as iron deficiency anemia. Iron supplements are important drugs used for the treatment and prevention of iron deficiency and related diseases. Common types of iron supplements include inorganic iron and organic iron, where inorganic iron such as ferrous sulfate may cause gastrointestinal discomfort such as nausea, vomiting, abdominal pain, diarrhea, etc., whereas organic iron (iron ascorbate Iron Ascorbate, iron glycinate Iron Glycinate) is known to improve iron absorption and bioavailability while usually having better gastrointestinal tolerance, making them ideal for iron supplementation.
