protein shake with stevia extract

I just bought a protein shake at Whole Foods to get more protein in since meat is just grossing me out right now. It's organic whey protein and everything sounded safe and great until I read that it contains Stevia extract. I remember my dietician telling me Stevia is safe but the organic extract hasn't been evaluated by the fda. Logically, I would think the less processed one would be safer but I'm still afraid to drink it. I was so excited, too. I wanted something to help my sweet tooth as well. Any input on this? Would you try it?
