I've actually been looking at X-Factor Advanced. The thing is I'm really not sure about it because of the fact that you have to lower your dosages of Fish Oil. Taking extra Omega 6 fatty acids will just increase your need for Omega 3's and upset the balance between the two. People get more than enough Omega 6 fatty acids in there diets so supplementing with this will further push you into an omega 3 deficiency. The reviews I have read of the product make it sound great. However I wouldn't want to give up my fish oil and CLA. That would be detrimental to my HDL and LDL levels. So these are the reasons against it, but I'm still on the fence about it. In fact recently my bad cholesterol has been too high and good cholesterol too low. However I have fixed that in the last 6 months or so with high fish oil intake, CLA, and Astaxanthin. If I was to stop or even lower dosages of those products it wouldn't be very good for my health....
