None of those drinks have potassium. The best way to get potassium is from eating foods like bananas, cucumbers, yogurt, etc. (think fruits and vegetables). Also, orange juice has potassium. If you're trying to increase your potassium intake I would also suggest lowering your sodium (salt) intake. Potassium and Sodium are important in maintaining your body's fluid and electrolyte balance. If you consume too much sodium it forces the potassium out of your body and your electrolytes are unbalanced.
