What is the better brand to try? I go to the gym at least 5 days a week and I am eating healthier--- so I was wanting to add something to it. There are so many acai berry companies out there. I know I dont want to be scammed. But really what is the difference in the Walmart Brand Acai supplement and one that you pay an arm and a leg for?? Help!!or Any other suggestions on what I could take to help me along?
