How much blood can you donate in a year?
According to the American Red Cross, most people can donate whole blood up to six times in a 12-month period. However, some factors, such as gender and weight, can affect how often a person can donate. For example, women can typically donate more frequently than men, and people weighing less than 110 pounds may be ineligible to donate whole blood.
Before donating blood, individuals should consult with a medical professional to determine their eligibility.
