The Water Kefir also known as tibic, is a crop of beneficial bacteria and yeasts for our immune and digestive system. This crop is responsible for feeding on sugary water to transform it into an excellent source of nutrients. Unlike Kombucha, the base of the KEFIR Water is water. This drink for athletes becomes an interesting isotonic that refreshes and provides quality sugars. Product made by tea • K Kombucha in Caguas, Puerto Rico. 16 oz bottle.
