I had surgery at Cleveland clinic in Weston Florida. The protocol after surgery is a tough one on what they allow. As long as the extract has no sugar they allow it. It helps when you need something new on the taste buds. I think the one I got was at whole foods. Banana flavor. I use it when I want a change in the shakes. The sugar free instant flavor coffees for great in shake also. I am now allowed caffeine again but find myself doing half calf a lot.
