How Does Caffeine Work?
Caffeine works by interacting with your brain’s chemical signals. Here’s how:
· Blocks adenosine: Adenosine is a neurotransmitter that causes drowsiness. Caffeine blocks its receptors, helping you feel awake.
· Boosts dopamine and adrenaline: These chemicals increase energy, improve mood, and enhance focus.
· Improves athletic performance: Caffeine is proven to enhance endurance.
Benefits of Caffeine (When Used in Moderation)
Here are some science-backed benefits of moderate caffeine consumption:
· Enhances mental alertness: Caffeine improves reaction time, focus, and concentration - ideal for work or studying.
· Reduces fatigue: It helps fight low energy, especially during night shifts or long drives.
· Supports physical performance: Caffeine can boost endurance and strength during exercise.
· Caffeine has also been linked to reduce the risk of various diseases
How Much Caffeine Is Safe?
According to the Mayo Clinic, up to 400 mg of caffeine per day (roughly 3–4 cups of brewed coffee) is considered safe for most healthy adults.
- However, sensitivity varies. Too much caffeine may cause:
· - Jitters or restlessness
· - Insomnia or disrupted sleep

Note: If you are looking for a way to enjoy coffee without any jitters, look for the Presto coffee Decaf or Half caf blends
