Matcha, the finely ground green tea powder, has gained immense popularity worldwide for its potential health benefits and unique flavor. However, concerns have been raised about its potential impact on cortisol levels. Cortisol, often referred to as the “stress hormone,” plays a crucial role in the body’s response to stress, regulating blood sugar levels, and aiding in the metabolism of fat, protein, and carbohydrates. In this article, we will delve into the relationship between matcha and cortisol, exploring the science behind the claims and providing an in-depth analysis of the topic.
Understanding Cortisol and Its Role in the Body
Before we dive into the relationship between matcha and cortisol, it’s essential to understand what cortisol is and its role in the body. Cortisol is a steroid hormone produced by the adrenal gland, released in response to stress, whether physical, emotional, or psychological. Cortisol’s primary function is to help the body respond to stress by:
- Suppressing the immune system
- Aiding in the metabolism of fat, protein, and carbohydrates
- Regulating blood sugar levels
- Maintaining blood pressure
Cortisol levels typically follow a circadian rhythm, peaking in the morning and decreasing at night. However, chronic stress can disrupt this natural rhythm, leading to elevated cortisol levels throughout the day.
The Impact of Elevated Cortisol Levels
Elevated cortisol levels can have a significant impact on the body, leading to:
- Weight gain, particularly in the abdominal area
- Insomnia and disrupted sleep patterns
- Blood sugar imbalances
- Osteoporosis
- Mood disturbances, such as anxiety and depression
Given the potential risks associated with elevated cortisol levels, it’s essential to understand how matcha may impact cortisol production.
Matcha and Cortisol: The Science Behind the Claims
Matcha, like other forms of green tea, contains a unique amino acid called L-theanine. L-theanine has been shown to have a positive impact on stress levels, promoting relaxation and reducing anxiety. However, matcha also contains caffeine, which can have a stimulating effect on the body.
Studies have shown that the combination of L-theanine and caffeine in matcha may have a synergistic effect, promoting alertness while reducing stress levels. A study published in the Journal of Functional Foods found that matcha consumption increased alertness and attention while reducing stress levels in healthy adults.
However, another study published in the Journal of Medicinal Food found that matcha consumption increased cortisol levels in healthy adults. The study suggested that the caffeine content in matcha may be responsible for the increase in cortisol levels.
The Role of Caffeine in Matcha
Caffeine is a well-known stimulant that can increase cortisol levels by:
- Stimulating the adrenal gland to produce more cortisol
- Blocking the action of adenosine, a chemical that helps regulate sleep and arousal
However, the amount of caffeine in matcha is relatively low compared to other sources, such as coffee or energy drinks. A typical 8 oz cup of matcha contains around 34-40 mg of caffeine, whereas an 8 oz cup of coffee can contain up to 180 mg of caffeine.
Matcha’s Unique Caffeine Profile
Matcha’s caffeine profile is unique in that it is released slowly into the bloodstream, providing a sustained energy boost over several hours. This slow release of caffeine may help mitigate the negative effects of caffeine on cortisol levels.
Other Factors That May Impact Matcha’s Effect on Cortisol
While the science behind matcha’s impact on cortisol is complex, other factors may also play a role. These include:
- Individual tolerance to caffeine: Some individuals may be more sensitive to the effects of caffeine, leading to increased cortisol levels.
- Matcha quality and sourcing: The quality and sourcing of matcha can impact its caffeine and L-theanine content, which may affect cortisol levels.
- Preparation method: The way matcha is prepared can impact its caffeine and L-theanine content. For example, using hot water can extract more caffeine from the matcha leaves.
- Time of day: Consuming matcha at different times of the day may impact cortisol levels. For example, consuming matcha in the morning may help regulate cortisol levels throughout the day.
Conclusion
In conclusion, the relationship between matcha and cortisol is complex, and more research is needed to fully understand its impact. While some studies suggest that matcha may increase cortisol levels, others have found that it can have a positive impact on stress levels and alertness.
To minimize the potential negative effects of matcha on cortisol levels, it’s essential to:
- Consume matcha in moderation: Limit matcha consumption to 1-2 cups per day.
- Choose high-quality matcha: Select matcha from reputable sources that is rich in L-theanine and low in caffeine.
- Prepare matcha correctly: Use lukewarm water and whisk the matcha gently to minimize caffeine extraction.
- Be mindful of individual tolerance: Pay attention to how matcha affects you personally, and adjust your consumption accordingly.
By being aware of the potential impact of matcha on cortisol levels and taking steps to minimize its effects, you can enjoy the many benefits of matcha while maintaining a healthy balance of cortisol in your body.

What is cortisol and how does it affect the body?
Cortisol is a hormone produced by the adrenal gland that plays a crucial role in the body’s response to stress. It helps to regulate blood sugar levels, blood pressure, and metabolism, among other functions. Chronically elevated cortisol levels, however, can have negative effects on the body, including weight gain, insomnia, and mood disturbances.
When cortisol levels are consistently high, it can disrupt the body’s natural balance and lead to a range of health problems. This is why it’s essential to find ways to manage stress and keep cortisol levels in check. Some people turn to matcha, a type of green tea, as a potential solution. But does matcha really have an impact on cortisol levels?
What is matcha and how is it different from regular green tea?
Matcha is a type of green tea that is grown and prepared in a unique way. Unlike regular green tea, where the leaves are steeped in hot water, matcha is made by grinding the entire leaf into a fine powder and dissolving it in hot water. This process allows the body to absorb the nutrients and antioxidants more easily.
Matcha contains high levels of L-theanine, an amino acid that is known for its calming effects. It also contains caffeine, but in smaller amounts than coffee or energy drinks. The combination of L-theanine and caffeine in matcha is thought to promote a state of relaxed alertness, which may help to reduce stress and cortisol levels.
Does matcha really lower cortisol levels?
Some studies suggest that matcha may have a positive impact on cortisol levels.
