Does Green Tea Increase Testosterone? (Expert's Opinion)

Green tea extract may aid in testosterone production due to the presence of flavonoids – catechins believed to benefit healthy testosterone levels [1].

In my coaching experience, I've observed clients who incorporated green tea extract into their routine often report improved energy and vitality.

However, other research revealed inconclusive results.

Its essential chemical components are L-theanine, potassium, iron, calcium, caffeine, and green tea epigallocatechin gallate (EGCG).

Some studies have shown that EGCG, a type of green tea extract catechins, can suppress estrogen, also known as the female hormone.

Reduced estrogen could increase testosterone levels as estrogen excess can negatively impact male sexual development, testis function, and sperm production [2,3].

In addition, green tea extracts are believed to elevate sex hormone binding globulin (SHBG), a necessary protein that, in turn, may cause androgen activity [4].

However, another study published in PubMed Central revealed that EGCG in green tea leaf extract actually decreased serum testosterone levels after twenty-six days of treatment [5].

According to research findings from PMC, regular consumption of green tea is not only safe but potentially beneficial for reproductive health, as well as liver and kidney functions, in male rats, suggesting similar positive implications for human health [6].

As of now, more research is necessary in order to gain more consistent results and determine the effect of green tea on testosterone production.

Speaking from experience, while green tea is generally beneficial, I've had clients who experienced side effects like irritability and sleeplessness, especially when consumed in large amounts. It's a reminder that moderation is key.

People who are sensitive to caffeine and tannins are more likely to experience these negative consequences [13].

That said, if you’re looking to increase your hormone levels naturally, I would recommend combining solid training and a balanced diet with a high-quality T booster.

Keep in mind that green tea acts as a natural diuretic, so excessive consumption may cause dehydration.

To avoid side effects, it's best to limit green tea intake to a maximum of sixteen cups per day.

Additionally, for those sensitive to caffeine, consider avoiding green tea at least five hours before bedtime to ensure it doesn't disrupt your sleep.
