If you want a product that will make you feel like a million bucks, try acai berries.  I tried a juice that had acai in it and feel like a new person!  My skin is definitely clearer and my doctor and I blame this on the antioxidants in the acai.  I have more energy which is totally amazing within itself.  Prior to taking acai, I was exhausted all the time, needing a nap every afternoon.  Finally, my diet works really well and I am losing steadily yet not getting tired and run down like before when I would follow a diet.
