Yes, chlorella is a prebiotic that helps increase the probiotic bacteria in your gut. According to studies, the presence of chlorella in the body reduced the harmful bacteria in the body and multiplied probiotic bacteria in the body. Chlorella is so incredibly fibrous that it’s hard for our saliva, gut, and intestines to break it down and must therefore be consumed as a ‘broken cell wall,’ i.e., it must be processed to remove the rigid walls of its cells and then eaten.
