Taking leptin supplements may help increase your levels. Typically, high leptin levels signal to your brain that your body has enough energy. This might seem like leptin supplements will help decrease your appetite, causing you to eat less and help with weight loss. However, this isn't always the case, especially if you have leptin resistance.
It's best to speak with a healthcare professional before taking any supplements if you want to lose weight. They'll develop a plan that's right for you.
