Matcha has soared in popularity over recent years. It is renowned for its high concentration of antioxidants, its energising properties, and its numerous health benefits. From sharpening your focus to supporting weight loss and promoting relaxation—matcha appears to be an all-in-one super-drink. But as with everything, the question arises: how much matcha can you drink per day without experiencing negative side effects? In this blog, we dive deeper into this question, so you can enjoy your daily dose of matcha in a safe and responsible way.

What makes matcha so special?

Before we dive into the details of how much matcha you can safely drink, it is important to understand what makes matcha so unique. Matcha differs from regular green tea because you consume the whole leaf. This means you ingest a much higher concentration of nutrients than you would when drinking a standard cup of tea, where the leaves are steeped and then discarded.

Matcha contains a powerful blend of antioxidants, caffeine, and an amino acid called L-theanine. This amino acid helps promote a state of relaxation while keeping you alert. Because of this, matcha is a favourite for those seeking sustained energy without the 'jitters' often associated with coffee.

The amount of caffeine in matcha

One of the most important aspects to keep in mind when determining how much matcha you can drink per day is the caffeine content. Matcha contains approximately 35 milligrams of caffeine per gram (roughly half a teaspoon). This is less than coffee, but because matcha is often consumed in larger quantities than regular green tea, the total amount of caffeine can add up quickly.

It is well known that excessive caffeine intake can have negative effects, such as insomnia, nervousness, and an increased heart rate. The recommended maximum daily caffeine intake for most adults is around 400 milligrams. This means you could drink about 11-12 grams of matcha per day before reaching that limit. In practice, this equates to roughly 5 to 6 cups of matcha per day.

What are the health benefits of matcha?

Matcha offers quite a few health benefits, especially when consumed in the right amounts. Some of the primary advantages include:

• Rich in antioxidants: Matcha is a potent source of antioxidants, particularly catechins such as EGCG (epigallocatechin gallate). Antioxidants help protect the body against free radicals and oxidative stress, which can contribute to better health and even slow down the ageing process.
• Improved focus and concentration: Thanks to the combination of caffeine and L-theanine, matcha provides an energy boost without the nervous side effects often linked to coffee. L-theanine promotes alpha brain waves, which are associated with relaxation and creativity.
• Support for weight loss: Matcha can assist with weight loss by accelerating the metabolism and promoting fat burning. It increases thermogenesis (the rate at which your body burns calories) without raising your heart rate.
• Relaxation and stress reduction: L-theanine promotes relaxation and reduces stress. It helps lower the production of cortisol (the stress hormone), which can contribute to a sense of calm.

How much matcha per day is optimal?

Now that we have discussed the benefits and the caffeine content, the question remains: what is the optimal amount of matcha per day? The ideal quantity depends on several factors, including your caffeine tolerance, your personal health, and your goals.

• For beginners: If you are new to matcha, it is a good idea to start with one cup per day. This gives your body time to adjust to the caffeine and benefit from the properties of matcha without the risk of side effects.
• For regular drinkers: If you are already accustomed to caffeine and drink matcha regularly, you can gradually increase this to 2 or 3 cups per day. This provides enough caffeine and L-theanine to boost your energy and improve focus without excessive caffeine intake.
• Maximum limit: As mentioned earlier, it is important not to exceed the recommended limit of 5 to 6 cups per day. This aligns with the safe limit of 400 milligrams of caffeine per day for most adults.

Possible side effects of too much matcha

While matcha offers many health benefits, excessive consumption can lead to some side effects, primarily due to the high amount of caffeine and antioxidants. Possible side effects of drinking too much matcha include:

• Insomnia: Due to the caffeine content, matcha—especially if drunk later in the day—can disrupt your sleep. Try to drink matcha before midday to prevent this.
• Stomach upset: Some people may experience stomach issues due to the high concentration of antioxidants in matcha, particularly if consumed on an empty stomach.
• Excessive caffeine intake: As with any form of caffeine, over-consumption can lead to jitters, an increased heart rate, and feelings of anxiety.

Matcha is a powerful drink that offers many health benefits, from improved focus and energy to supporting weight loss and relaxation. However, as with all things in life, it is important to consume matcha in moderation. For most people, 1 to 3 cups per day is a safe and healthy amount to enjoy all the benefits of matcha without the risks of excessive caffeine intake.

If you find that you are sensitive to caffeine or if you already consume many other caffeinated beverages, adjust your matcha intake accordingly to stay within safe limits.
