Serving of matcha is between 2–4 grams (1/2–1 teaspoon), which would then contain anywhere between 38–176 mg of caffeine (2).For reference, coffee beans have 10–12 mg of caffeine per gram. An 8-ounce (240 mL) cup containing 10 grams of coffee has roughly 100 mg of caffeine (2).So, depending on how concentrated the matcha tea is, a serving of matcha tea could have a lower or higher caffeine content than a serving of coffee.SummaryMatcha contains 19–44 mg of caffeine per gram or about 38-176 mg of caffeine per cup. The caffeine in a typical serving of matcha depends on how much powder is used, how fresh it is, and how it’s brewed.Matcha is higher in caffeine than regular green tea.One cup (240 mL) of green tea is estimated to contain about 30 mg of caffeine. A serving of matcha made with 2–4 grams (1/2–1 teaspoon) of powder could have a caffeine content between 38–176 mg of caffeine (2, 7).However, studies suggest that the caffeine content of green tea varies depending on the type, freshness, and brewing time (8).One study found that caffeine in green tea ranged from 10–23 mg of caffeine per gram of tea leaves or 20–90 mg of caffeine per cup (8).With 19–44 mg of caffeine per gram, matcha is higher in caffeine than most regular green teas (2).SummaryMatcha contains more caffeine per gram and in a typical serving than most green teas. A typical cup of matcha contains 38–176 mg of caffeine, while a regular cup of green tea may contain 20–90 mg of caffeine.To make a cup of matcha tea, you need matcha powder, a mug or cup, hot water, and a bamboo matcha whisk (chasen) or regular whisk. You may also want to use a small mesh sieve or tea strainer.Once you have your tools, follow

Thank you for joining the Huberman Lab Neural Network — a once-a-month newsletter with science and science-related tools for everyday life. This newsletter aims to provide you with actionable information in a condensed form.In the episode “Using Caffeine to Optimize Mental & Physical Performance,” I discuss one of the most widely used substances in the world: caffeine.Most people are drawn to caffeine's ability to increase alertness and reduce feelings of sleepiness and fatigue. This newsletter explains how caffeine affects the brain and body to produce these effects and describes science-supported tools, caffeine schedules and dosages to best leverage caffeine for physical and mental performance.Caffeine Dosage & ScheduleIt’s important to determine an optimal caffeine dose and schedule. Follow these tips to discover your personalized caffeine dose:Dose: Start with 1 to 3 mg of caffeine per kilogram body weight. If sensitive, start lower.For example, I weigh ~100 kilograms (220 pounds) so a tolerable dose of caffeine is 100 to 300 milligrams. However, I often consume more than that since I'm quite caffeine-adapted.Research the caffeine-containing beverages (soda, tea, coffee, energy drinks) that you consume.Popular coffee and energy drinks can contain anywhere from 50 to 500 and as much as 800 milligrams of caffeine (!), depending on the size and source.Avoid extended consumption of high levels of caffeine — there is an increased risk of headaches, anxiety, irritability and blood vessel damage.Caffeine is a diuretic, causing the loss of fluid, sodium and other electrolytes.Consume equal volumes of water with your caffeine to avoid jitteriness, blurry vision or a low blood sugar feeling.Ideally, add a small pinch of sea salt, table salt or electrolyte-replacement powder like LMNT to the water (Note: LMNT is a Huberman Lab sponsor).Supplement: If you experience any anxiety or jitteriness when consuming even smaller doses of caffeine, consider supplementing with theanine to reduce those negative effects. Many energy drinks include 100-200 mg theanine for this reason.Timing TipsTo time caffeine consumption appropriately throughout your day, follow the tips below:If you tend to experience an afternoon crash, consider delaying your caffeine intake for 90 to 120 minutes, but otherwise, caffeine first thing is

The stimulating effect of caffeine is one of the main reasons so many people enjoy a daily cup of coffee. You can expect an 8-ounce cup of coffee to provide just under 100 milligrams (mg) of caffeine and a 12-ounce cup with approximately 140 mg. But where does that fall in terms of recommended daily allowances of caffeine? Can you expect similar caffeine amounts from home-brewed coffee vs. a cup you pick up from a coffee shop? This article examines how much caffeine you can expect from your coffee, including factors influencing caffeine content, and gives a general guideline on daily caffeine limits. Stefania Pelfini, La Waziya Photography / Getty Images Milligrams of Caffeine in One Cup of Coffee The amount of caffeine in a standard cup of coffee can vary depending on factors such as the type of coffee beans, the brewing method, and the serving size. On average, an 8-ounce cup of brewed coffee contains approximately 90–95 milligrams (mg) of caffeine. However, this amount can fluctuate, with some cups containing as little as 70 mg and others having as much as 140 mg or more. In addition, if you drink decaffeinated coffee, you are still getting some caffeine. On average, an 8-ounce cup of decaf coffee contains around 2–5 mg of caffeine. It's important to be mindful of caffeine intake, especially if you're sensitive to caffeine's effects. Following is a closer look at some of the main factors involved in determining caffeine amounts. Coffee Size Not all cups and mugs of coffee of the same portion size. Logically, there's 3 times as much caffeine in a 24-ounce mug vs. an 8-ounce cup of the same brew. If your goal is to keep your daily caffeine intake to an allotted amount, it may be best to opt for a smaller portion, especially if you drink more than one coffee daily. Coffee Type Certain types of coffee and brewing techniques result in slightly higher caffeine levels. However, some studies have found no significant differences in caffeine content when comparing specialty-grade brews to other popular brands. Some of the types of coffee that may have the most caffeine per serving are: Robusta coffee beans: Robusta beans typically contain more caffeine than Arabica beans. Robusta beans are often used in espresso blends and instant coffee, contributing to higher caffeine levels in these types of coffee.Dark roast coffee: Contrary to popular belief, dark roast coffee beans usually contain slightly less caffeine than lighter roasts. However, dark roast coffee often has a bolder flavor, which may give the perception of a higher caffeine content.Espresso: While espresso shots are smaller in volume than a standard cup of coffee, they tend to have a higher concentration of caffeine due to the brewing method: the pressure and short extraction time used in making espresso extract more caffeine from the coffee grounds.Cold brew coffee: Cold brew coffee is made by steeping coffee grounds in cold water for an extended period, typically 12 to 24 hours. This method extracts
