where does caffeine come from in energy drinks
Caffeine Caffeine is also a common ingredient of soft drinks, such as cola, originally prepared from kola nuts. Soft drinks typically contain 0 to 55 milligrams of caffeine per 12 ounce serving.[181] By contrast, energy drinks, such as Red Bull, can start at 80 milligrams of caffeine per serving.

For example, time zones at sea are based on GMT. In many locations (but not at sea) these offsets vary twice yearly due to daylight saving time transitions.
