Despite its physical properties of being a weak acid (~pH 3), kombucha has been shown to alkalize the body (much like lemons, which are also acidic). Our blood is slightly alkaline, around pH 7.4 (pH 7 being neutral).
The pH of gastric acid is 1,5 to 3,5 in the human stomach. The acids in kombucha can stimulate the secretion of gastic juices. Overall, these acids ensure a smoothly functioning digestive system.
If you are sensitive to acids we suggest to include kombucha slowly into your diet and see how your body responds.
