When you donate blood you just sit quietly for a short time and they tell you to take things relatively easy for the next day or so, and drink some extra fluids over the next 24 hours, so it doesn't take long. If you are otherwise healthy your body will replace that much blood within a week or so.

In Scotland there is a minimum interval of 12 weeks between blood donations of 500 ml. That probably means that 4 weeks would be okay for quite a number of people, and 8 weeks for nearly everybody, but it is 12 weeks to be completely safe in every case.

Your blood volume is replaced within a few hours. Plasma is restored following a meal. Your red cells replace themselves more slowly, usually in about 4-8 weeks.
