Kombucha is known for its ability to help aid in digestion, stimulate metabolism, and decrease infections, and studies have shown that along with probiotics and antioxidants, kombucha also offers a variety of vitamins and minerals. One study conducted in the Republic of Macedonia in 2001 looked at the mineral and water-soluble vitamins in kombucha that was made with 0.7% sucrose and 5 g/L of black tea. The researchers found that the kombucha contained vitamins B1, B6, B12, and C, along with minerals like zinc, copper, iron, manganese, nickel, and cobalt, all of which contribute to better health.
