血铁损失
Each time you donate blood, you losebetween 220-250 mg of iron. If you donate a Power Red, you lose twice thatamount, about 470 mg of iron. It may take up to 24-30 weeks for your body toreplace the iron lost through a blood donation. That time may vary, dependingon what your iron level was before donating and if you take iron supplements ormultivitamins with iron.
每次献全血，你会损失220-250mg的血，如果选择单采红细胞，你会损失470mg铁。你的身体可能需要24到30周来补充献血失去的贴，这个时间点可能会有所不同，取决于你在献血前的血铁含量，以及你是否摄入复合维生素或铁补充剂。

过量摄入铁补充剂的风险 （不构成医学建议）
Iron supplements can cause side effects,which are described on the packaging. Side effects can include constipation,diarrhea or an upset stomach. If these symptoms become bothersome, you shoulddiscuss alternative options such as a lower dosage with your health-careprovider.
Taking iron can mask other healthconditions that are more serious such as gastrointestinal (GI) disease. Theymay also be harmful to people who have an iron overload syndrome such ashereditary hemochromatosis. You should discuss your risk factors and healthhistory with your health-care provider before adding iron supplements to yourroutine.
Although iron supplements are not usuallyharmful to adults when taken as directed, accidental ingestion of iron bychildren can be fatal. You should keep all iron-containing products out of thereach of children. In case of ingestion or emergency, seek medical assistanceor call a poison control center immediately.
铁补充剂可能有副作用，这会在药品包装上注明。常见副作用有便秘，腹泻或胃不舒服。如果这些症状让你烦躁，你应该与医师咨询并谈论方案，如降低剂量。
服用铁补充剂可能掩盖其他更严重的健康问题，如胃肠道（gastrointestinal,GI）疾病。这也可能对患有血色素沉着症（血色沉着症1型，HFE）的人有害。请咨询医师
铁补充剂对成人通常无害，但儿童意外摄入可能知名。你应该把铁补充剂当作药品细心保管不让儿童接触。如果儿童误食，请拨打急救电话。

铁补充剂的范例

这是单一铁补充剂的范例。有180粒药片，每份含有325mg硫酸亚铁，即54mg铁离子。正常成年人推荐每日摄入至少18mg铁，即一粒药片摄入361%铁元素。但人体对铁元素吸收不会到100%，且人体对不超过毒副作用剂量的摄入有自我排出能力。

带翻译才看得懂

我个人认为更需要把铁和蛋白质一起补充，多吃肉蛋奶，毕竟血红蛋白是蛋白质大分子，铁仅仅是其中的一个中心原子而已，没有充足的蛋白质肯定不行的。

指导很详细

居然还有单采红细胞吗，相当于一次采900ml的全血，涨知识了

献血小板也需要补铁嘛？

优质好文

番外：钙摄入
Importance of calcium
If you are a platelet donor, you may be told to increase yourcalcium intake a day or two prior to your donation. The anticoagulant that isused during a platelet donation temporarily binds with the calcium in yourblood to be removed from your body. Making sure you have plenty of calcium inyour system will help you feel comfortable during your donation.
Your body needs calcium to perform many regular functions. Calcium is thefoundation for strong, healthy bones, muscles and teeth. Blood coagulation,transmission of nerve impulses, muscle contraction and relaxation, normalheartbeat and other functions also require small amounts of calcium.
Calcium boosters
Milk, Yogurt, Cheese, Salmon, Sardines, Broccoli, Pinto beans,Dates, Figs, Tofu, Spinach, Almonds, Calcium fortified orange juice,
Calcium busters
Caffeine, Smoking cigarettes, Alcohol
如果你准备捐献血小板，你可能被告知在上机前1-2天增加钙的摄入。在血小板抽离过程中使用的抗凝血剂会暂时和你即将被抽走的血液中的钙质结合。确保你身体的钙质充足，将使你的身体保证舒适。
你的身体的许多基础功能需要钙。钙是强壮，健康的骨骼，肌肉和牙齿的组成成分。凝血，肌肉收缩和舒张，正常的心跳等功能也需要钙。
促进钙吸收的食物
牛奶、酸奶、奶酪、三文鱼、沙丁鱼、西兰花、斑豆、椰枣、无花果、豆腐、菠菜、扁桃仁（杏仁）、加钙橙汁。
影响钙吸收的食物
咖啡因，烟草和电子烟制品，酒精（他们对健康也有危害，建议不要食用）

请注意：不要自我判断需要补铁，请在医师指导下进行！网页链接
