Always check labels, a lot of stevias come with additives like maltitol and dextrose, especially the liquid ones and they are noticeable in taste as they are very sweet right away. Pure stevia is discreetly sweet and obviously more expensive XD
I completely stopped taking Stevia due to this very reason. A friend of a friend had to be admitted to the hospital due to some liver problems after taking the wrong type, marketed as ‘stevia’. I now take all drinks plain and on some days just with salt.
Be very careful.
