Drink 8-10 glasses of water per day to ensure you are well-hydrated. Eat a well-balanced meal within two hours of your donation appointment. Avoid fatty, greasy foods and significant amounts of dairy. You will not be compensated for fatty donations of plasma, though fatty donations can easily be avoided with a healthy diet. Maintaining a healthy diet and drinking plenty of non-caffeinated, non-alcoholic beverages the day before and the day of donating is very important. Prior to your donation, we recommend avoiding strenuous exercise, alcohol consumption, and smoking.
