Hydroxycut has been around for more than a decade, and is currently one of the most popular weight loss supplements in the world.
There are several different types, but the most common one is simply called “Hydroxycut.”
How it works: It contains several ingredients that are claimed to help with weight loss, including caffeine and a few plant extracts.
Effectiveness: One study showed that it caused 21 lbs (9.5 kg) of weight loss over a 3 month period (5).
Side effects: If you are caffeine sensitive, you may experience anxiety, jitteriness, tremors, nausea, diarrhea and irritability.
Bottom Line:Unfortunately, there is only one study on this supplement and no data on long-term effectiveness. More research is needed.
