Tribulus is used in the Active Formula of the CardioTrim health supplement line.

Tribulus, or Tribulus terrestris, a traditional Ayurvedic herb commonly known as the "puncture vine", has been used for centuries in Europe as a treatment for impotence and as a stimulant to help enhance sexual drive and performance.

Tribulus has been shown to increase LH (luteinizing hormone) production and boost testosterone levels. Tribulus exerts its testosterone-elevating effects by stimulating an increase in LH, which is responsible for "telling" your body to produce testosterone. Testosterone is a vital hormone responsible for increasing muscle size and strength. As a result, Tribulus has also been shown to increase energy and stamina, and to speed muscle recovery after muscle fibers have been broken down as a result of exercise.

Finally, tribulus is used in various Ayurvedic medicines for the treatment of certain kidney disorders.

Overall, studies on Tribulus show it helps:

• Promote healthy libido
• Promote fertility and reproduction
• Promote healthy testosterone levels
• Promote decreased recovery time after exercise
• Promote normal kidney function
