Boba calories refer to the amount of energy provided by bubble tea drinks and their toppings, especially tapioca pearls. A typical 16–24 oz bubble tea can range from 200 to over 500 calories, depending on ingredients. The tapioca pearls alone often add 100–200 calories, since they’re made from starch and sweetened syrup. https://bubblebobatea.net/bubble-tea-calories/
