What is the use of caffeine as a supplement?



You should first know that many foods contain caffeine (chocolate, tea, coffee, guarana, yerba mate, cola nuts... etc.) and that this molecule (in the family of methylxanthines) was so named by the German chemist Friedrich Ferdinand Runge which isolated it from coffee in 1819. By the way, theine and caffeine are the same molecule, their name differs depending on their source.


What are the therapeutic properties of caffeine?

This molecule is primarily a stimulant. Unlike a tonic substance or plant that tends to supportEnergy; anything that is stimulating brings a surplus of strength and boldness by tapping into the body's reserves. These gluttonous substances rake every bit of energy and burn them quickly. Which, in the long run, tends to exhaust you. Heavy coffee drinkers know from experience that these substances should be consumed sparingly and sporadically.


That said, caffeine:

- increases alertness and cognitive performance (learning),

- helps fight fatigue,

- improves endurance and muscle strength (slightly),

- effectively fights certain types of Migraines.


Caffeine is useful for weight loss because it speeds up the basic metabolism. As a result, your body consumes more calories. In addition, it appears that caffeine may decrease appetite in the short term.


Side effects

But beware, it also increases the heart rate and excites the nervous system... which tends to make it more "irritable."  It is not recommended for high blood pressure or cardiac arrhythmia.

Finally, if you are already consuming good amounts of caffeine every day, you will need higher than average doses to achieve the desired effects. This is likely to give you more side effects than benefits.
