Which are the best known effects of caffeine?
Several studies have shown that caffeine, if consumed in moderated quantities, has a positive effect on endurance activities. Caffeine makes the use of fats for energy production easier, preserving thus the body's carbohydrate stocks.
Moreover, caffeine defers the perception threshold of tiredness in sportsmen, allowing them to also defer their personal limits. It promotes vigilance, which may be important in night events and events which require a lot of concentration.
Is there a risk of overdosage?
People who drink a lot of coffee may easily exceed the recommended daily maximum dose of caffeine. This may have contrary effects. Some troubles may appear if you consume more than 6mg/kg/day: insomnia, nervousness, digestive problems,..
Which OVERSTIM.s products contain caffeine?
The energy gels CAFEIN'GEL and RED TONIC Sprint Air contain caffeine from guarana. The quantities contained in each tube are not excessive (it is necessary to consume several tubes to have the same quantity of caffeine as contained in one cup of coffee).
These two gels are recommended for difficult sections during physical exertion, as they contain rapid-release carbohydrates.
