A lot of people turn to the pharmacy for different products when it comes to keeping germs and sickness away from them.
There are so many different kinds of products you can buy over the counter that claim to reduce your risk of getting sick.
Anything from powers and tablets you can mix with water to boost your levels of Vitamin C to syrups that you can add to hot tea.
Of course, getting enough vitamins and minerals will keep your body healthy, but are they actually effective when it comes to preventing you from getting sick?
"More than likely those products aren't going to do any harm, but there's no good, hard core science to say that they actually work. It's not likely to hurt anything but it's also not likely to help," said family care physician, Dr. Tamara Spriggs.
She says it's important to make sure you're getting enough sleep at night too. That's eight hours for adults and eight to 10 hours for kids.
Doctors say the best way to prevent getting sick is by constantly washing your hands and not touching your hands to your face.
