It should have caffeine in it, but maybe not as much. Just as an example this brand has up to 32 mg of caffeine. Average cup of coffee has somewhere between 75 - 200 mg.

Personally I use Now Foods brand for most all of my supplements. I've been using their Policosanol, Alpha Lipoic Acid, Green Tea, and Super Odorless Garlic for 5+ years now.
Mind you, this is simply my opinion. I've not tried many other brands nor kept any records to compare results.
