Any advice for my wife

My wife does not have a reddit so she asked that I ask all you wonderful people for some advise on her behalf. She is trying to lose a little weight like 10-15 pounds. The problem is that she can’t seem to get past her current weight. We eat healthy, and we have been going to the gym regularly. We both know that over time this is a recipe for success and we are going to keep with that lifestyle. However she is looking for a little boost, some kind of supplement that will aid in weight loss or fat loss. She will not take anything that increases heart rate or blood pressure though. So none of those jittery weight loss pills. Is there any other product out there? Thank you!
