Can i take cla and garcinia cambogia together, to aid in weight loss?

Supplements: Sure but it would be best to figure out individually if either supplement works alone before combining them. The data for high quality CLA at appropriate doses is fair (combined with diet and exercise). I'm not impressed with the GC studies and the quality of sources varies dramatically. Given the expense of these supplements my advice would be to boost dietary sources (grass-fed) meat and dairy.
