The safe daily limit of Red Bull consumption for healthy adults is up to five 8.4 fl oz cans per day, which corresponds to 400 mg of caffeine. This aligns with recommendations from authorities like the European Food Safety Authority (EFSA) and the US FDA. Pregnant and nursing women should limit their caffeine intake to 200 mg per day, which is about two and a half cans of Red Bull. For adolescents, caffeine intake should be limited even more, to around 100 mg or less per day, roughly one 12-ounce serving of Red Bull or less. Drinking more than the recommended amounts can lead to caffeine overdose symptoms such as nausea, rapid heart rate, and anxiety, and in rare cases, excessive consumption has been linked to serious heart problems and other health risks. Repeated overconsumption may also carry risks related to sugar and artificial sweeteners in some versions of Red Bull. In summary:
- Healthy adults: Up to 5 cans (8.4 oz each) per day (400 mg caffeine)
- Pregnant/nursing women: Limit to about 2.5 cans (200 mg caffeine)
- Adolescents: Limit to about 1 can (100 mg caffeine)
- Overconsumption risks include heart issues, caffeine overdose symptoms, and other health problems.
