This natural testosterone booster works through different mechanisms to benefit both sexes. Here’s the science and where to get it.
Several studies show that Tongkat Ali (an extract of the Eurycoma longifolia bush), elevates testosterone levels in men. However, a newer study found that the herb raises T levels in women as well.
What the Researchers Did
First, they recruited 25 cyclists, 13 of them male and 12 of them female. All belonged to the same over-50 cycling club. Each cyclist received 200 mg. of Tongkat Ali daily for five weeks. The researchers took before, during, and after measurements of cortisol, IGF-1, DHEA, testosterone, and grip strength.
While levels of cortisol, IGF-1, and DHEA remained largely unchanged, free and total testosterone levels went up significantly in both men and women, as did grip strength. The top graph shows the changes in the testosterone levels of men, and the second graph shows the changes in the women:
Clearly, the Tongkat Ali raised testosterone levels in both sexes and consequently increased their strength, too.
The testosterone increases in men were apparently caused by elevated luteinizing hormone (LH) and follicle-stimulating hormone (FSH), along with concurrently lowered estradiol levels.
The increase in women’s testosterone levels was caused by a significant decline in sex-hormone binding globulin (SHBG). That means the herb prevented the testosterone that women make naturally from being chemically bound up and made inaccessible to the body by SHBG.
Older men and women can benefit from taking Tongkat Ali to raise testosterone levels. While it’s true that previous studies have concentrated on its testosterone-elevating effects in younger men, it’s not known whether these findings would hold true for younger women, too.
Younger women generally have lower SHBG levels than older women and thus might not feel much of a difference from Tongkat Ali. Younger women also have to be wary about the potentially masculinizing effects of elevated levels of testosterone. (That said, some women can suffer from low T, just like men. Info here.)
However, if you’re a man who feels he might benefit from higher levels of testosterone (or an older woman who feels the same), try taking a daily dosage of at least 200 mg. of Tongkat Ali. Our formula, Alpha Male, contains highly purified Tongkat Ali.
While the formula was created for men, it also contains the compound forskolin, as well as the herb Tribulus Terrestris, both of which benefit women, too. While forskolin elevates testosterone in men, it doesn’t have the same effect in women. Instead, it works to reduce female belly fat.
Similarly, while some studies of Tribulus Terrestris show it to increase testosterone production in men, it only stimulates androgen receptors in women’s brains, helping them respond better to their natural levels of circulating hormones.
