Caffeine is one of the most commonly consumed psychoactive substances in the world. Found in coffee, tea, soda, and chocolate, caffeine is a stimulant that can help increase alertness, improve concentration, and even enhance physical performance.
But how much caffeine is too much? And what are the potential risks associated with consuming too much caffeine?.
What is caffeine?
Caffeine is a natural stimulant found in a variety of plants, including coffee beans, tea leaves, kola nuts, and cocoa beans.
It works by blocking adenosine, a neurotransmitter that causes drowsiness, and increasing the production of other neurotransmitters like dopamine and norepinephrine, which can increase energy and alertness.
How much caffeine is safe?
According to the Mayo Clinic, up to 400 milligrams of caffeine per day is considered safe for most adults. However, individual tolerance levels can vary widely, and some people may be more sensitive to the effects of caffeine than others.
It’s also important to note that caffeine is a diuretic, which means that it can increase the frequency of urination and lead to dehydration if consumed in large amounts.
