I love the Pure Inventions Green Tea Extract drops in both teaberry and peach. I mix them together and they taste amazing. Definitely helps me drink more water to stay hydrated. They are a bit pricey but well worth it. There is stevia in them but I don’t taste it at all and there’s no wonky after taste. We tried them at a spa in our area and I’m so glad we did. I bought both the peach and raspberry for my daughter and myself. On their website they are $24.00. Don’t let that stop you. They are so worth it.
