That can make it extremely tricky to figure out how much caffeine is in your drink.
One exception is cola-key in beverages.
Some brands may choose to list the caffeine levels of a product on the label to keep consumers informed.
And thats a good thing.
For example, coffee generally has more caffeine than tea and sodas.
(Although in lattes, you may consume one or two shots of espresso.)
What Does Caffeine Do to Your Body?
Caffeine is best known as a natural stimulant that boosts mental alertness.
When caffeine is ingested through food and beverages, its absorbed into your bloodstream.
Then, a series of chemical reactions happen.
When caffeine reaches the brain, it blocks adenosine receptors to keep you mentally alert.
When consumed in low doses, caffeine may also improve memory and cognitive function, perNutrientsin 2021.
How Much Caffeine Can You Have in a Day?
This amount is equal to four or five cups of brewed coffee.
This depends on how the body reacts to caffeine and how fast the body breaks down the stimulant.
Caffeine can stay in your system for up to 12 hours, according to theSleep Foundation.
Drinking caffeinated beverages can trigger a rise in cortisol, the stress hormone.
This is why its important to keep tabs on how much caffeine youre really getting every day.
TheFDAstates that consuming 1,200 mg of caffeine is considered a toxic amount and could lead to seizures.
A caffeine dose of 10,000 mg or more is regarded as a life-threatening level for adults.
This life-threatening level could be at a lower dose for those who are sensitive to caffeine and for children.
