Yohimbe has been one of the most popular aphrodisiac, stimulant, and tonic supplements for men and women for years. 

What does it do and what scientific studies give evidence to support this?
Yohimbe's recent popularity has been ignited not only by it's effects as an aphrodisiac, but new research shows it is a vasodilator, which means that it increases blood flow to the extremities and appendages. Translation: Stronger workouts, increased vascular definition and faster exercise recovery!
Research also shows yohimbe could be an herb with very effective antioxidant potential, which can help your body fight infections and cellular breakdown.

Where does it come from?
Yohimbe comes from the bark of a tree that grows primarily in West Africa. When ingested, the body converts it to yohimbine and assimilates it into the bloodstream. Yohimbine, an alkaloid, is the primary active ingredient of yohimbe. Natrol's herbal yohimbe bark is made from the finest sources in the world.

How much should be taken?
