I recently started taking this brand as I used to take another well known brand but wasn't really seeing much of a result. We will see after my Dr. appointment with blood work in a few weeks. I love the antioxidant properties that Acai provides. Since I haven't had my blood work done yet, I won't know for sure but I do feel better taking this brand with no issues. I only ordered one bottle to see if it was good or just as good as my last brand and after taking it for the past few weeks, I will def. be reordering again after this bottle is gone.
