I want to know if garcinia cambogia 60% (maritzmayer pills) is useful for fat burning.

Doesn't burn fat but: It's not yet known how effective garcinia cambogia is; some studies show it helps, others suggest it doesn't- see http://www.med.nyu.edu/content?ChunkIID=21727/ It doesn't "burn fat." No pill helps as much as a long-term healthy diet & exercise. See http://bit.Ly/1dhw9ht re: a good diet. See http://bit.Ly/178bmuf for a supplement I'm more impressed with, but no pill is magic for weight loss.

Don't use it: Garcinia cambogia is in most weight loss supplements, and can cause liver failure.It was also used in Hydroxycut which was taken off the market as people died from using it. I see a handful of patients per month with abnormal liver tests after using this medicine. I would NOT recommend it. There is no "magic pill" for weight loss. Diet and exercise remain the #1 way to lose weight and keep it off
