Most health experts and regulatory guidelines suggest that for healthy adults, consuming up to one energy drink per day is generally safe, which translates to about 5 to 7 energy drinks per week. This is mainly because the safe daily caffeine limit is around 400 mg, and many energy drinks contain around 80 to 200 mg of caffeine each. Consuming more than this amount regularly can increase risks of negative health effects such as anxiety, heart palpitations, sleep disturbances, and other issues. Specifically:
- It is advised to limit energy drink consumption to 16 ounces (around one can) per day and avoid energy shots with very high caffeine content.
- Drinking 5 or more energy drinks per week is associated with increased risk of adverse effects including stress, depressive moods, and sleep problems.
- Children, teenagers, pregnant or nursing women are generally advised to avoid energy drinks altogether.
- Be cautious of the total caffeine intake from other sources when consuming energy drinks.
So a practical safe weekly limit for most healthy adults is roughly one energy drink per day or up to 7 per week, while fewer is safer to avoid potential health risks.
