Does green tea lower testosterone?

In this article, we will answer the question “Does green tea lower testosterone?”, how does green tea extract improve testosterone levels, what foods lower testosterone levels, and how to boost your testosterone naturally.

Does green tea lower testosterone?

Yes, green tea can lower testosterone levels. The antioxidants, called catechins, present in green tea are linked to reduced levels of testosterone. 

Excessive consumption of green tea can trigger the release of sex hormone-binding globulin or SHBG. This hormone degrades the testosterone into dihydrotestosterone, or DHT, thus lowering the levels of the sex hormone.

How does green tea extract improve testosterone levels?

Green tea has great anti-inflammatory potential due to which it protects the Leydig cells of the testes against inflammation. Leydig cells are the manufacturing sites of testosterone. Green tea impedes the activity of prostaglandins, inflammatory modulators, to boost testosterone production. 

The catechins, predominantly epigallocatechin, interfere with the activity of the enzyme 5-alpha reductase. This enzyme converts the testosterone into dihydrotestosterone or DHT. By inhibiting the enzyme, green tea extract contributes to improved testosterone levels.

Green tea extract can promote homeostasis by regulating the production of hormones. It promotes testosterone levels if they are low and vice versa. 

What foods lower testosterone levels?

Soy and soy-based products 

Excessive or frequent consumption of soy-based products like edamame, tofu, soy milk, and miso can decrease your testosterone levels. More research is needed to confirm this effect of soy and soy-based products.


Mint is known for its refreshing and cooling effect. Little do you know that spearmint and peppermint can lower testosterone levels. The research on the testosterone lowering properties of mint is limited to women and animals. Therefore, we cannot say for sure if mint is the culprit.

Licorice root

Licorice is a common sweetening agent in candies and beverages. It is also known for its cough-suppressant properties. Several studies have shown that licorice root can result in a dip in your testosterone levels. Most of the research on this matter is centered around women and animals so no evidence is conclusive as of yet.

Vegetable oil 

Commonly used vegetable oils like canola, soybean, corn, and cottonseed oil are packed with polyunsaturated fats. This class of fatty acids is praised for its healthfulness but it can negatively affect testosterone levels. There is a lack of scientific data to confirm this effect of vegetable oil.


Flaxseeds are touted for their healthy fat, fiber, mineral, and vitamin content. Flaxseeds are particularly rich in omega-3 fatty acids, a type of PUFA, linked with a reduction in testosterone levels. However, the research is limited.

Processed foods 

Processed foods have earned a bad reputation due to their filthy rich sodium, calorie, and added sugar content. Another reason why processed foods are unhealthy for you is the presence of trans fats. 

Frequent exposure to trans fats has been linked with an increased risk of heart disease and type 2 diabetes. It also lowers the levels of testosterone and damages the reproductive system.


Infrequent alcohol intake is not problematic but excessive consumption can lead to a reduction in the levels of testosterone. One study has shown that acute alcohol intoxication in women elevates testosterone levels.

Safe to say the effects of alcohol on testosterone levels are unclear and need more investigation to form a conclusion.


No doubt nuts are a rich source of healthy fats, fiber, and important minerals. However, research has shown that the SHBG protein of the nuts makes them bad for your testosterone levels. 

A high PUFA content is another reason that explains the testosterone lowering effects of nuts. However, the research is limited and inconclusive.

Dairy products 

Dairy cows are injected with hormones to increase their milk production. The milk of such cows contains residues of these hormones which can interfere with the testosterone levels of the milk consumer.

Other factors 

Factors like aging, a sedentary lifestyle, chronic drug use, obesity, and diabetes can result in hormone or lower testosterone levels. 

How to boost testosterone naturally?

Following a healthy lifestyle can do wonders for you let alone boost your testosterone levels. Experts recommend eating a balanced diet, refraining from overeating, exercising regularly, and getting 8 hours of uninterrupted sleep can help boost testosterone levels.

Alternatively, you can use testosterone boosters such as Testofuel, TestRX, Nugenix Ultimate, etc. These are plant-based dietary supplements. We recommend consulting your doctor before adding them to your diet.
