Tongkat Ali (Eurycoma Longifolia) is well known for raising testosterone production and improving sex drive. (1,2) Whether you are working hard to increase or maintain muscle mass at the gym or have a sudden decrease in libido or sexual function (3), testosterone is most likely on your mind. If not, it should be! A decrease or abnormally low amounts of testosterone could lead to a decrease in meeting your health goals. You may be thinking, my sex drive is A-OK and I am doing just fine at the gym thank you very much, it may be interesting to note that testosterone naturally starts decreasing from the age of 25-30 and can have a 1-2% decrease every year! If at any point you start experiencing a reduced sex drive, loss of lean muscle mass, fatigue and weight gain (particularly around your abdominal area) you might start to question your testosterone levels. If your suspicions are correct and low testosterone is to blame, never fear Tongkat Ali is here to save the day!
