I've been using the NutriBullet PRO for 2 months and from the first few days I've had a noticeable increase in my energy levels. I use it for breakfast every day and some days for my supper as well. I think it acts as a sort of pre-digestion process so my stomach doesn't have to work so hard.
I have both of the Nutribullet the first one and the newer one ni love them both get up in thye morning to fix my power drinks and night time i make a relaxation drink to sleep better . Thank you Nutribullet
