Prebiotics are identified as the non-digestible Food ingredients that sustain Probiotics. They mainly come from types of carbohydrates, particularly fibre, which the Body is unable to digest. The beneficial bacteria in the gut consume this fibre for its nutrients that benefit the colon cells and in turn lead to a healthier digestive system.
While you can take prebiotics and probiotics together (a process known as microbiome therapy), you don't need to for them to work.
As prebiotics are a food source for the good bacteria that we consume from foods, many medical professionals suggest taking them with a main meal.
In most cases, prebiotics should improve your Digestion & Gut Health within a 4 week period.
