Yohimbe is a plant that contains the active compound yohimbine. Yohimbine acts as an alpha-2 adrenergic antagonist, meaning it blocks receptors that normally inhibit the release of hormones like testosterone. Several studies have examined whether supplementing with yohimbe or yohimbine increases testosterone levels in humans.
Some research has shown that yohimbine can increase testosterone levels in men:
- A study in elite soccer players found that taking 20mg of yohimbine daily for 21 days increased testosterone levels by around 15%.
- Another study gave yohimbine to healthy men and found an over 30% increase in testosterone levels in some participants. However, there was significant individual variability in response.
However, other studies show less clear or no effects:
- Multiple studies have shown that taking yohimbine before exercise does not increase testosterone or growth hormone levels compared to placebo.
- One study in rugby players taking 12mg of yohimbine for 5 days showed no effects on testosterone levels.
So the current research presents an unclear picture:
- Yohimbine may help increase testosterone levels in some people when taken regularly at higher doses (over 20mg). However, individuals can vary dramatically in their hormonal response.
- Taking yohimbine right before exercise does not appear effective for acutely increasing testosterone.
- The increases in testosterone seen are generally moderate, not dramatic changes. People with initially low testosterone may be more likely to benefit.
Why the mixed results?
- Yohimbine has a complex interaction with multiple hormones. It may work better in those with high stress or impaired sexual function.
- General healthy men already have optimized hormonal function, meaning a ceiling effect on further increases from any supplement.
- Differences in yohimbine source, dosing, genetics likely play a role.
In summary, yohimbe and its active compound
yohimbine can potentially increase testosterone levels when taken regularly at sufficient doses, but effects are inconsistent across individuals and studies. Any testosterone-boosting benefits would likely be moderate, not dramatic.
Those struggling with
low testosterone or sexual dysfunction may want to experiment with yohimbine under medical supervision. However, changes to lifestyle, diet, sleep, and stress management should be explored first.
