Caffeine molecule png8/30/2023 Matcha green tea is another high-caffeine tea. For comparison, green teas contain 20–45 mg, while white teas deliver 6–60 mg per cup (237 ml) ( 12, 13, 14). This gives black tea a characteristic bold and sharp flavor and increases the extent to which caffeine from the leaves infuses hot water ( 4).Īn average cup (237 ml) of black tea packs 47 mg of caffeine but can contain as much as 90 mg. What sets them apart is the time of harvest and level of oxidation of the leaves ( 4).īlack tea leaves are oxidized, while white and green tea leaves are not.

In addition, some studies suggest that drinking it regularly, even in moderate amounts, can cause chronic headaches and migraines ( 8, 9, 10).įurthermore, caffeine is considered mildly addictive, and some people may be more susceptible to developing a dependence ( 9). In large doses, caffeine has been associated with anxiety, restlessness, and difficulty sleeping. That said, consuming high amounts - such as single doses over 500 mg - may raise some concerns ( 2, 3). Department of Agriculture (USDA) and European Food Safety Authority (EFSA) define a safe caffeine intake as up to 400 mg per day, 200 mg per single dose, or 1.4 mg per pound (3 mg per kg) of body weight ( 1, 2, 3).ĭue to its stimulating effects, caffeine has been linked to health benefits like enhanced alertness, improved athletic performance, elevated mood, and increased metabolism ( 4, 5, 6, 7). “This content and the claims made should be investigated, along with the ingredients and the caffeine content in the Prime energy drink.An estimated 80% of the world’s population enjoys a caffeinated product daily.īoth the U.S. “A simple search on social media for Prime will generate an eye-popping amount of sponsored content, which is advertising,” he wrote.
