Testosterone Booster

A Testosterone Booster for Couples

There have been a lot of studies showing that the testosterone booster Tongkat Ali (an extract of the Eurycoma longifolia bush), elevates testosterone levels in men. However, a fairly recent study found that the herb raises testosterone levels in women as well as men.

Here's what you need to know:

Ralf Henkel of the University of the Western Cape and Ruxiang Wang of the Shenyang Center for Disease Control and Prevention recruited 25 older cyclists, 13 of them male and 12 of them female. All of them belonged to the same over-50 cycling club.

Each cyclist received 200 mg. of Tongkat Ali every day 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 believed to be caused by a significant decline in sex-hormone binding globulin (SHBG). That means that 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. Two capsules of our formula Alpha Male® contain the same amount of highly purified Tongkat Ali used in the study.

While the formula was created for men, it also contains the compound forskolin, as well as the herb Tribulus Terrestris, both of which have been shown in studies to benefit women, too.

While forskolin has been shown to elevate 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 have shown it to increase testosterone production in men, it only stimulates androgen receptors in women's brains, thus helping them respond better to their natural levels of circulating hormones.
