Matcha Green Tea Latte: Benefits, Side Effects and How to Make It

A matcha green tea latte combines matcha powder — finely ground green tea leaves — with steamed milk, giving you a creamy drink with more antioxidants than a typical cup of brewed green tea, since you consume the whole leaf rather than just steeped water.

What Is Matcha Green Tea Latte Good For?

Matcha comes from the same Camellia sinensis plant as regular green tea, but the leaves are ground into a fine powder and consumed whole rather than steeped and discarded. This means a cup of matcha delivers more of the plant's antioxidants, including catechins, than an equivalent cup of green tea infusion. Our complete matcha guide covers grades and storage.

Potential benefits associated with matcha include:

• L-theanine for calm focus: Matcha has notably more L-theanine than steeped green tea, an amino acid associated with alertness paired with a sense of calm, rather than the jittery effect some people get from coffee.
• Steady energy: Matcha's caffeine is released more gradually than coffee's, thanks to L-theanine, which may support sustained energy without a sharp crash.
• Antioxidant support: Catechins in matcha are associated with reduced oxidative stress and may support heart and skin health as part of an overall healthy diet.
• Metabolism: Some research associates green tea catechins with modest increases in calorie burning, though matcha alone isn't a weight-loss solution.

Matcha is not a treatment for high cholesterol, high blood pressure or cancer, despite some of the enthusiastic claims you may see online. NCCIH's review of the evidence found that green tea lowers LDL cholesterol only to a small extent, with no effect on HDL cholesterol, and that its link to lower heart disease risk shows up in some Asian population studies but not in Western ones — so any effect on these conditions is, at most, modest and works alongside, never instead of, medical care.

How to Make a Traditional Matcha

Add 1–2 teaspoons of matcha powder to a bowl, then add a small amount of hot (not boiling) water. Whisk briskly with a bamboo whisk (chasen) in a zigzag motion until frothy and free of lumps.

Matcha Green Tea Latte Recipe

Ingredients:

• 3/4 cup milk of choice (coconut, oat or dairy all work well)
• 1 teaspoon matcha powder
• 1/4 cup hot water
• Sweetener to taste

Preparation:

1. Whisk the matcha powder into the hot water until smooth and lump-free.
2. Heat the milk separately until warm, then froth if desired.
3. Combine the matcha and milk, sweeten to taste, and serve hot or over ice.

Iced Matcha Latte

Follow the same steps, but use cold milk and pour over a glass of ice instead of heating. A slice of lemon or lime can brighten the flavor.

Side Effects and Precautions

• Caffeine: Matcha's caffeine content can cause insomnia, a faster heart rate, irritability or headaches in sensitive people. As a beverage, NCCIH notes no general safety concerns for adults, but concentrated green tea supplements (not brewed tea or matcha whisked as usual) have been linked to nausea and increased blood pressure, and, rarely, liver injury — check with your doctor before taking green tea extract supplements.
• Iron absorption: Green tea, including matcha, is commonly thought to reduce iron absorption from food because of its tannins; if you're managing low iron, it's reasonable to avoid drinking it with iron-rich meals.
• Digestive discomfort: Some people experience mild stomach upset or constipation with regular matcha use.
• Quality matters: Choose organic or reputably sourced matcha, since lower-quality matcha can carry pesticide or heavy metal residue.
• Pregnancy: Talk to your doctor about safe caffeine limits if you're pregnant or breastfeeding.

FAQ

Does matcha latte have caffeine?

Yes. Matcha contains more caffeine per serving than steeped green tea, though generally less than coffee, and its effect tends to feel steadier due to the L-theanine content.

Is a matcha latte healthier than a coffee latte?

It depends on your goals. Matcha offers more antioxidants and typically a gentler energy curve, while coffee has more caffeine per cup. Neither is inherently "healthier" — it comes down to what works for your body.

Can I make a matcha latte without dairy?

Yes. Oat, almond, coconut and soy milk all work well and are common choices for matcha lattes.

The Bottom Line

A matcha green tea latte is a tasty way to get more of green tea's antioxidants than a standard infusion, along with a steadier caffeine lift. It isn't a treatment for any medical condition, so enjoy it as part of a balanced diet rather than a cure-all.
