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. The caffeine in these drinks either originates from the ingredients used or is an additive derived from the product of decaffeination or from chemical synthesis. Guarana, a prime ingredient of energy drinks, contains large amounts of caffeine with small amounts of theobromine and theophylline in a naturally occurring slow-release excipient.[182]
Nightcap (beverage) Originally, a "nightcap" was understood to be alcoholic, the idea being that it warms you up and helps you sleep, just like the garment of the same name.[7] That changed in 1930, when the non-alcoholic drink Ovaltine was advertised as "the world's best 'night-cap' to ensure sound, natural sleep".[7] An ingredient of Ovaltine is magnesium which helps to induce relaxation.[8]
