Blocks Adenosine Receptors → Increases Neurotransmitter Activity

Caffeine blocks adenosine, a neurotransmitter that promotes relaxation and sleep.
This indirectly increases the release of dopamine and serotonin, making you feel more alert and positive.

Boosts Dopamine → Enhances Mood & Motivation

Caffeine stimulates dopamine release, which works in tandem with serotonin to regulate mood.
This is why caffeine can temporarily improve mood and reduce depression symptoms in some people.

Increases Cortisol & Norepinephrine → Short-Term Mood Lift

Caffeine triggers the release of stress hormones (cortisol, epinephrine, norepinephrine).
This can create a temporary feeling of energy and motivation, but excessive intake can lead to serotonin depletion over time.
May Help Reduce Depression Risk (In Moderation)

Some studies suggest moderate caffeine intake (2-3 cups of coffee per day) is linked to a lower risk of depression.
This may be due to its effects on neurotransmitter balance, including serotonin.

How to Maximize Serotonin Benefits from Caffeine
Pair Caffeine with L-Theanine (100-200 mg) → Enhances focus & prevents crashes.
Consume Tryptophan-Rich Foods (Eggs, Salmon, Turkey, Nuts) → Supports serotonin production.
Don’t Overdo It (Max 400 mg/day) → Too much caffeine can deplete serotonin long-term.
Cycle Caffeine (3-5 Days Off Every 4-6 Weeks) → Prevents neurotransmitter burnout.
