Zotrim promises quite a few results and specifically claims that their formula will decrease the rate of gastric emptying, which matches up with the study conducted on guarana, yerba mate, and damiana. The problem is that their numbers do not. They call it 5% weight loss in 6 weeks, which is about 10 pounds if you are 200 pounds, less if you are lighter. The study specifically cites about 11.2 pounds in 45 days, and that was regardless of weight. It also used a significantly higher dose of each ingredient than is likely used in Zotrim being that they won’t name the amounts. We would not trust Zotrim, and the consumer reports seem to support the idea that it doesn’t work.
