Hi my name is Linda. I want to take Garcina Cambogia once a day,how many mg. are most effective and which brand? I am diabetic @210 lbs. at 5 6 . learning to eat better more fresh veggies and lean chicken. trying to eat right carbs, I have taken it before but ran out and can t remember what brand it was. I am and artist , I eat well during the day, but usually up until 4 and 5am. then I eat poorly. have tried the garcina with green coffee and raspberry, did not like it. I heard 800 mg. was a good does. I am leaving for Greece in November of 2014. so I need advice now.
