ELI5: Explain Like I'm 5

Immunostimulant

An immunostimulant is like a helper for your body's immune system. Your immune system is like an army that protects your body from bad germs and viruses that can make you sick.

When you take an immunostimulant, it helps your immune system do its job better by making the soldiers in your army stronger and more alert. This way, they can fight off the bad germs and viruses faster and keep you from getting sick.

Just like how you eat healthy food and exercise to keep your body strong, immunostimulants help keep your immune system strong and healthy too!
