Licorice can negatively affect testosterone levels due to its unique compounds and their impact on hormonal balance. Research suggests that licorice can affect hormone levels and potentially lead to a decrease in testosterone. In one study, 25 men who consumed 7 grams of licorice root daily experienced a 26% reduction in testosterone levels within just one week.
Below are some of the reasons why licorice can be bad for testosterone:
- Glycyrrhizin Content: Licorice contains glycyrrhizin, which can inhibit the enzyme 11β-HSD type 1, involved in converting cortisol to its inactive form. This can lead to elevated cortisol levels, negatively impacting testosterone production.
- Increased Cortisol Levels: Regular consumption of licorice can result in higher cortisol levels, which may suppress testosterone production and disrupt overall hormonal balance.
- Reduced Testosterone Conversion: High cortisol levels from licorice can interfere with the conversion of testosterone to its active form, further lowering effective testosterone levels in the body.
- Possible Disruption of Hormonal Regulation: Glycyrrhizin’s effects on cortisol can lead to broader hormonal imbalances, affecting the body’s ability to maintain optimal testosterone levels.
