The connection between the brain and gut is a powerful one and it’s almost impossible to neglect the way they affect each other when something is out of balance. When you’re having digestive issues, you’ll most likely experience mood swings, brain fog, fatigue, and even depression. Here is why.

It also acts like a hormone and that’s why you might know it as the “happiness hormone,” as the majority of publications refers to it as such.
