From the Dr Oz Site:
Don't get duped by phony, ineffective products. When looking to purchase a supplement, look carefully at the list of ingredients. When looking for a green coffee bean supplement, it should contain the chlorogenic acid extract, which can be listed as any of the following:
• GCA (green coffee antioxidant)
• Svetol
Also, look for a capsule that contains at least 45% chlorogenic acid. More than 45% is okay, but pills with less than this amount have not been tested in studies that demonstrate weight loss.
If the bottle doesn't list ingredients, don't buy it! On the ingredient list, you should see no fillers and no artificial ingredients. Also, don't be fooled by the word "pure" if you see it on a label. If you see the word "pure," and you don't see Svetol or GCA, consider another choice.
The capsules will range in dosage as well. They can be 200mg, 400mg, 800mg, etc
