Yohimbine

Yohimbine comes from the bark of Pausinystalia yohimbe, a tall evergreen tree from Central Africa. The extract from the bark has the chemical action of blocking alpha-2 receptors. When these receptors are turned on, they slow down the sympathetic nervous system. Blocking these receptors helps keep it turned on. Theoretically, this would cause your body to burn more energy.

Three studies on this supplement for weight loss have conflicting results. Therefore, it is currently unclear whether yohimbine is effective in weight loss or not.

Side effects include: fast heart rate, high blood pressure, anxiety, panic attacks, tremors, water retention, sweating, nausea, vomiting, and some others.

It is important you discuss any weight loss or exercise plan with your doctor. Only you and your physician can decide what is best for you. Some people have certain conditions that prevent them from doing all exercises, and goal body weights may be different for different people. You need to discuss all these things with your physician before starting any weight loss or exercise program.
