Most of the Alcachofa products do not contain any caffeine. We have a testimonial on the site from Lori that says:
The first natural weight loss product I have found that has ever worked for me. They really curb your appetite without any jitters. I have lost 13 lbs in 2 months. Would recommend to everyone.
The Alcachofa Blend Bitter Orange/Green Tea capsules contain stimulants derived from natural sources: caffeine from Green Tea Extract and synephrine from Bitter Orange Extract. We have not received any reports of users having the jitters from this product.
