How does Tongkat Ali work?

Tongkat Ali, also known as Eurycoma longifolia or Longjack, is an herb known for increasing libido. It works by increasing the amount of unbound, or free, testosterone by reducing levels of sex hormone binding globulin (SHBG). Free testosterone is biologically active and can be potent in the body, while bound testosterone is not. The herb is reported to not only affect libido but also potentially influence androgen-like phenotypes, enhancing vitality. While there's some evidence of its efficacy, the exact mechanisms in the brain and body are not fully understood 1 2 3.

Tongkat Ali is also recognized for having slight effects on other hormones like DHEA and improving the condition of individuals with hyperestrogenism. It's beneficial for both men and women and is usually taken in dosages ranging from 200 to 600 milligrams per day, with adjustments based on body size and personal responsiveness. It's important to monitor blood work when taking supplements like Tongkat Ali to track their effects on hormone levels 1 4.

Usage doesn't seem to require cycling off regularly, but if someone chooses to cycle, an eleven months on and one month off schedule is generally deemed reasonable. Nonetheless, it is advised to check with a healthcare provider before starting, discontinuing, or cycling any supplements 5.
