Matcha has several potential upsides, but it also has a few drawbacks worth knowing. The main benefits are its green tea polyphenols, caffeine and simple ingredient profile when you drink it plain.
The main downsides are caffeine sensitivity, possible stomach discomfort, effects on iron absorption and the added sugar that can come with café-style drinks.
Pros of Matcha
It Contains Green Tea Polyphenols
Matcha is made from finely ground green tea leaves, so it naturally contains plant compounds called polyphenols. These include catechins such as EGCG.
Green tea has been studied for its antioxidant activity and possible effects on cardiovascular and metabolic health. The research is more extensive for green tea overall than for matcha specifically, so it is better to think of these compounds as one positive part of the drink rather than a guaranteed health benefit.

It Can Help With Alertness
Matcha naturally contains caffeine. For many people, that makes it useful in the morning or whenever they want a caffeinated drink.
The amount of caffeine depends on the matcha and how much powder you use, so a stronger serving will generally give you more caffeine.
Plain Matcha Has No Added Sugar
Pure matcha mixed with water does not contain added sugar. That gives you complete control over how sweet you want your drink to be.
The same is not always true for café drinks. Premixed powders, syrups and toppings can add a significant amount of sugar. See Do Matcha Drinks Have Sugar in Them? for more on where that sugar comes from.
It Can Be an Alternative to Coffee
Some people simply prefer matcha to coffee because of the flavour, preparation or amount of caffeine in their usual serving.
Neither drink is automatically better for everyone. If you are deciding between them, read Is Matcha Better Than Coffee?
Cons of Matcha
It Still Contains Caffeine
Caffeine can be a benefit and a drawback. If you are sensitive to it, matcha may contribute to jitters, trouble sleeping, a racing heartbeat or feeling anxious.
Your total caffeine intake matters. Coffee, tea, energy drinks, chocolate and other sources all count toward the amount you consume in a day.
It Can Upset Some People's Stomachs
Some people find matcha uncomfortable on an empty stomach or when they make it very strong. Nausea, stomach irritation or general discomfort can happen, especially if you are sensitive to caffeine or tea compounds.
Using a smaller serving or drinking it with food may feel better for some people.
Tea Can Affect Iron Absorption
Tea polyphenols can reduce the absorption of non-heme iron, which is the type of iron found mainly in plant foods. This is more relevant for people who already have low iron or are at higher risk of iron deficiency.
If iron is a concern for you, the timing of your matcha around meals may be worth discussing with a healthcare professional.
Matcha Drinks Can Become Sugary Quickly
The matcha itself may be unsweetened, but a matcha latte can include sweetened milk, flavoured syrup, pre-sweetened matcha powder, cold foam or toppings.
That does not make every matcha latte unhealthy. It simply means the full drink matters more than the matcha powder alone.
Good Matcha Can Be Expensive
High-quality matcha takes careful growing, processing, grinding and storage. That can make it more expensive than standard tea bags or some other everyday drinks.
Quality also varies. A stale or poorly made matcha may taste overly bitter, dull or gritty, which can make it harder to enjoy.
Is Matcha Worth Drinking?
For many people, yes. Matcha can be an enjoyable source of caffeine and green tea polyphenols, especially when it fits naturally into your routine.
It is not a superfood you need to drink, and more is not automatically better. Pay attention to your caffeine tolerance, what you add to the drink and how your body responds.
