CAFFEINE 101
WHAT IS CAFFEINE?
Caffeine is a stimulant that affects your central nervous system. It naturally occurs in coffee, tea, cacao and several plants, and it is also added to products such as energy drinks, supplements, gums and caffeine gummies.
Its most recognizable effect is helping you feel more awake and temporarily reducing the sensation of fatigue.
YOUR BRAIN ON CAFFEINE
HOW DOES CAFFEINE ACTUALLY WORK?
Caffeine primarily works by interfering with adenosine signaling. Adenosine is one of the signals associated with increasing sleep pressure throughout the day.Adenosine builds up
The longer you're awake, the stronger your body's natural drive for sleep becomes.
Caffeine gets involved
Caffeine can occupy adenosine receptors, temporarily reducing the strength of that tiredness signal.
You feel more alert
The result can be increased wakefulness, perceived energy and alertness.
TIMING MATTERS ⚡
HOW LONG DOES CAFFEINE TAKE TO KICK IN?
Many people begin noticing caffeine within approximately 15 to 45 minutes.
The timing isn't identical for everyone. Your dose, whether you've eaten, your caffeine tolerance and your individual metabolism can all influence how quickly you notice the effect.
CAFFEINE DOESN'T DISAPPEAR QUICKLY
UNDERSTANDING CAFFEINE HALF-LIFE
Caffeine's average half-life in healthy adults is roughly five hours, although it can vary substantially between individuals.You consume an example dose of 100mg caffeine.
Roughly 50mg could still remain.
Roughly 25mg could still remain.
You may stop feeling the strongest caffeine effect long before all of the caffeine has left your body. That's one reason late caffeine can interfere with sleep.
WHERE DOES CAFFEINE COME FROM?
COMMON SOURCES OF CAFFEINE
Coffee
One of the most common caffeine sources, but caffeine amount varies significantly by size and preparation.
Tea
Black tea, green tea and other varieties naturally contain caffeine in different amounts.
Energy drinks
Energy beverages can contain widely different amounts of caffeine depending on the product.
Chocolate
Cocoa naturally contains smaller amounts of caffeine and related compounds.
Tablets
Concentrated caffeine products make accurately tracking your dose particularly important.
Gummies
Caffeine gummies provide a portable format without carrying around a drink.
TOLERANCE
WHY DOES CAFFEINE STOP HITTING?
CAFFEINE TOLERANCE IS REAL.
Regular caffeine use can cause your body to adapt to some of its effects. As a result, the exact same dose may feel less powerful over time.
The answer isn't necessarily to keep increasing your caffeine. Continually increasing your dose can make it easier to consume more caffeine than you intended.
If caffeine isn't feeling as effective anymore, consider your overall intake and frequency before automatically increasing the dose.
WHAT HAPPENS IF YOU STOP?
CAFFEINE WITHDRAWAL
If someone regularly consumes caffeine and then suddenly stops, temporary withdrawal symptoms can occur.USE CAFFEINE LIKE A TOOL ⚡

Know your sensitivity.
If caffeine consistently makes you shaky or uncomfortable, consider using less.
Don't blindly stack.
Multiple caffeinated products can add up surprisingly fast.
More isn't always better.
