There’s not a man alive who doesn’t wish his testosterone levels were higher—except maybe Justin Bieber. That’s because testosterone is the hormone that’s associated with manliness. It’s one of the main reasons that men have more muscle, greater strength, less fat, and a bigger sex drive than our female counterparts. So when our testosterone levels start to fall, due to age, stress, or just regular, intense training, we need to do everything in our power to pick them back up. These three ingredients can help make a big difference in your testosterone levels.
D-ASPARTIC ACID
This amino acid, also known as D-asparaginic acid, stimulates the release of luteinizing hormone (LH), which travels via the bloodstream to the testicles where it causes a boost in testosterone production. One Italian study reported that healthy men supplementing with D-aspartic acid had a 30% increase in their LH levels.
FENUGREEK
This herb contains high amounts of Furostanolic saponins, which are natural plant chemicals that can boost testosterone levels. It also enhances performance, as one study reported that men taking fenugreek for eight weeks increased their bench-press and leg-press strength twice as much as those taking a placebo.
DAMIANA
This shrub, also known as Turnera diffusa, is native to Mexico and Central and South America. Research from the University of Mississippi discovered that Damiana contains the active ingredients pinocembrin and acacetin, which indirectly work to keep testosterone levels high while inhibiting estrogen in the body.
