Green tea: what it does, how to brew it, and what to watch for

Want a simple drink that wakes you up and may help your health? Green tea is a good place to start. It’s full of antioxidants called catechins, especially EGCG, and has less caffeine than coffee. That combo is why many people drink it daily—taste, mild boost, and possible health perks.

Health benefits and what to expect

Green tea can help in small, useful ways. Regular drinking is linked to better heart markers like lower blood pressure and improved cholesterol in some studies. Some people notice mild weight management help when green tea replaces sugary drinks and is part of an active lifestyle. Matcha—powdered green tea—packs more antioxidants and more caffeine, so effects can be stronger.

Don’t expect miracles. Green tea supports health; it doesn’t replace medicine. If you have a condition like diabetes, high blood pressure, or a heart problem, keep following your treatment plan and talk to your doctor about adding green tea.

Brewing, servings, and safety tips

Want the best cup? Use fresh water below boiling—about 160–180°F (70–80°C). Steep 1–3 minutes for regular green tea. Longer steeping makes it bitter and can increase caffeine. For matcha, whisk a small scoop into hot water or milk; it’s stronger, so use less.

How much is safe? For most people, 2–4 cups a day is reasonable. That gives a useful amount of catechins without too much caffeine. If you’re sensitive to caffeine, try decaf or limit cups to one or two.

Watch for interactions: green tea can reduce iron absorption from plant foods, so don’t drink it with an iron-rich meal if you’re low on iron. Also, very high-dose green tea extracts have caused liver problems in rare cases. If you’re on blood thinners like warfarin, some herbal supplements, or strong prescription drugs, check with a pharmacist—green tea can change how medicines work.

Pregnancy and breastfeeding? Stick to low to moderate amounts (one to two cups) and ask your provider before taking supplements or concentrated extracts.

Quick shopping tips: choose whole-leaf or reputable brand bags, store in a cool dark place, and prefer plain leaves over flavored ones if you want true green-tea benefits. If you consider a green tea supplement, get advice from a health pro first.
