铁是合成血红蛋白的重要原料，当铁摄入量不足、吸收量减少、需求量增加、铁利用障碍或丢失过 多时，会导致血红蛋白合成减少，进而引发贫血。铁剂是治疗缺铁性贫血的重要药物，但很多患者在服 用过程中常因用药细节不当导致疗效不佳，甚至因副作用而中断治疗。 要知道，铁剂的服用时间、搭配禁忌和个体化选择，直接影响药物的吸收率和患者的胃肠耐受性。 两种补铁剂各有优劣 口服补铁剂常见的如硫酸亚铁、富马酸亚铁、琥珀酸亚铁等，尽量空腹服用。在空腹状态下，胃内 没有食物干扰，铁剂能较快通过胃部进入小肠，而小肠是铁吸收的主要部位，这有利于铁剂中的铁离子 与肠黏膜细胞充分接触，吸收率更高，效果更好。 不过，部分口服补铁剂可能刺激胃黏膜，引发恶心、腹痛、便秘或腹泻等副作用；部分剂型（如溶 液）有明显金属味，可能引起患者排斥。 若空腹不耐受，可改为餐中或餐后1小时温水送服，并搭配维生素C片促进吸收。胃肠功能好者优 先选择空腹补铁剂，并搭配维生素C；胃肠敏感者优先选择餐时或餐后服用的补铁剂，减少胃肠道刺 激。 特殊人群需注意孕妇贫血风险高，建议小剂量分次服用。如每日分2-3次，必要时选择缓释剂型； 儿童优先选择口感好、刺激性小的液体或颗粒剂型。 ...

Core Viewpoint - The article highlights the increasing cost pressures on lithium iron phosphate (LFP) production due to rising prices of key raw materials, particularly ferrous sulfate, which is influenced by the declining operating rates in the titanium dioxide industry [2][3]. Group 1: Industry Dynamics - The titanium dioxide industry is experiencing a decline in operating rates, currently at 65.83% as of June 2025, down over 12 percentage points since April, leading to a tightening supply of ferrous sulfate [2]. - The current market price for ferrous sulfate has risen to 1800-1900 RMB per ton, driven by low inventory levels, which may soon surpass the cost levels of iron powder-based processes [2]. - Approximately two-thirds of the iron sources used in domestic LFP production come from ferrous sulfate, indicating its critical role in the cost structure of LFP manufacturing [2]. Group 2: Cost Structure Sensitivity - The cost structure of LFP is highly dependent on the stability of raw material markets, which include iron, phosphorus, and lithium sources, making it sensitive to price fluctuations in upstream industries [3]. - The pricing mechanism in the LFP industry is primarily based on lithium pricing, which is influenced by the average monthly price of battery-grade lithium carbonate, but increasing volatility in phosphorus and iron prices could compress profit margins if not managed effectively [3]. Group 3: Strategic Responses - There is a growing consensus among LFP companies to integrate upstream resources to mitigate cost pressures, with companies like Hunan Youneng securing phosphate resources in Guizhou for self-supply and Longpan Technology partnering with CATL to establish a lithium carbonate processing plant [4].
