What to eat after a blood draw?

Iron-rich Foods

Hemoglobin consists of iron as an important part of it. Iron is essential for the carrying of oxygen by the red blood cells. New red blood cells are needed after you give blood. Foods rich in iron come in to play a role in replenishing the red blood cells. 

Examples of foods rich in iron include beans, fish, nuts, poultry, spinach, and red meat. Some cereals also contain a significant amount of iron and hence can be eaten as well. For the iron to be easily absorbed, you can add foods rich in Vitamin C such as Citric fruits and grapes.

Folate foods

Folic acid plays a role in the manufacture of red blood cells.. Foods such as spinach and kale and orange juices contain folic acid. You can also include cereals and pieces of bread in your diet. 

Foods rich in Riboflavin

Riboflavin is also important in the production of red blood cells. It helps in the conversion of complex carbohydrates into energy which prevents lethargy that happens when blood is drawn from the body. 

Foods rich in riboflavin include green vegetables, eggs, poultry, spinach, and yogurt. 

Vitamin B-6 Foods

Vitamin B -6 hydrolyses proteins to simple nutrients that can be absorbed.  Foods rich in Vitamin B-6 include spinach, potatoes, bananas, red meat, and fish.


Fluids are very important to take in plenty after donating blood. They help in hydrating the body and reduce the chances of fainting.It is advisable not to smoke or consume alcohol for 24 hours after a blood draw.

Avoid Fatty and fried foods

You should avoid eating foods like batter and mayonnaise. Foods such as creamy soups, ice creams, and cheesecake are too sugary and it is best to avoid them.

Moreover, foods such as sausage, duck, bacon, and pork belly are also not good for someone who has donated blood. 

What are the tips for faster recovery after a Blood draw?

  • You should avoid any strenuous activities as well as lifting heavy objects. This can cause weakness and dizziness.
  • Take time to rest and reduce stress to recover faster. Use the day for relaxation..
  • Focus on a diet that helps in replenishing the red blood cells. Salty and sugary foods are not the best.
  • Drink plenty of water and stay hydrated at all times.
  • You can carry a water bottle and snack even before donating blood to prepare yourself for donating blood. 

What side effects can you have after blood has been drawn?

Minor bleeding

The injected area tends to bleed for a while after blood is drawn. You can prevent this by keeping the area wrapped in a bandage for 3 hours after donating blood. In case you continue to bleed, use a bandage as you apply more pressure to the site.

Lightheadedness and Fatigue

After blood is drawn you can feel nauseated, dizzy, and lightheaded due to dropped blood pressure. It is best to lie down after blood is drawn. You can also drink a lot of water and continue to do so for days after donating blood and avoid alcohol.

What happens to the body when blood is drawn?

The replacement of red blood cells happens very fast after blood is drawn. This is done by the red bone marrows which are signaled by the reduced oxygen levels after some red blood cells are lost during donation.

The red bone marrow, therefore, begins to replenish the lost blood cells. Drinking a lot of fluids helps this. Some people might experience nausea and fatigue as the water and iron are lost. 

Donating blood can also be good in regulating the levels of iron in the blood. Too much iron might cause damage to the blood vessels. Even if blood is not drawn, the body has a way of ensuring iron levels are balanced. It is important to take balanced foods at all times.
