Help our patients in their recovery by donating the blood and platelets they need.
The vast majority of people feel fine after giving blood, however it is always important to eat a healthy, well-balanced meal before donating and to be well-hydrated. This allows your body to recover as quickly as possible after donation, as well as provide the best possible blood product for our patients.
Eating an iron-rich diet, especially in the days preceding your donation, is an important way to help your body recover after blood donation.
Whole blood can be donated every 56 days. Platelets can be donated every seven days, up to 24 times a year. The usual interval for blood donation is every eight weeks.
The Food and Drug Administration (FDA) has specific criteria for blood donation eligibility. In general you must:
Your body needs iron to make new RBCs and to perform other metabolic tasks. Iron comes from either pre-existing iron stores in your body or iron in the food you eat. Many menstruating women may not have enough iron stored in their body to make RBCs to replace their donation. Men have more iron stores; however, with frequent donation, iron stores in men can also become depleted.
Low iron stores are common, particularly in women of childbearing age.
Eating a well-balanced, iron-rich diet is helpful. The recommended daily allowance (RDA) for iron varies by gender, but is at least 8 mg for all adults.

What about iron supplements?
If diet alone does not replace all the iron lost from blood donation, taking iron supplements may help.
There are many different types of iron supplements. The University of Chicago Medicine Blood Donor Services does not provide prescriptions for over-the-counter iron products. Please ask your doctor if you have any questions about your underlying health conditions and starting iron supplements. Your doctor or pharmacist may be able to assist you in deciding what dose, type and duration of iron supplement to choose. Donors who take one multivitamin with iron (typically 18 mg elemental iron) each day for three months, or one iron caplet (commonly 325 mg tablets of ferrous sulfate, which provide about 65 mg of elemental iron) each day for about two months, can replace the amount of iron lost in one unit of donated RBCs.
Do not take more than the recommended dosage of iron because higher doses can be harmful. Iron-containing supplements should be properly stored to prevent accidental ingestion by babies and children. If your child swallows an iron pill, contact a poison control center right away.
