What is the recommended caffeine dosage?

The recommended dosage of caffeine depends on an individual's body weight. Generally, it is advised to consume 1 to 3 milligrams of caffeine per kilogram of body weight. For example, someone weighing 100 kilograms (220 pounds) could safely ingest 100 to 300 milligrams of caffeine in a single dose. It's important to adjust this dosage based on personal tolerance and whether you are accustomed to consuming caffeine regularly. If you are not used to caffeine, it's suggested to start at the lower end of this range 1.
