Paullinia cupana (seed)

Supplementenergycaffeinefocusstimulant

Guarana is basically ‘plant caffeine’—used for energy and focus. It can be effective, but it’s not gentle: dosing matters, and it can worsen anxiety, insomnia, and high blood pressure in sensitive people.

Key Benefits

Energy and alertness support (caffeine source)
Focus support in some people
Often used in energy blends and pre-workouts

Common Issues It May Help With

low energy
fatigue (stimulant support)

How To Use (Simple)

Capsules/powder: follow label carefully (caffeine content varies)
Avoid late-day dosing to protect sleep
If caffeine-sensitive, start with very low dose or skip

Taste / Notes

Bitter (powder).

Evidence Level

Caffeine effects are well-established; specific guarana studies exist but most benefit is attributable to caffeine/stimulants.

Cautions

Avoid with uncontrolled high blood pressure, panic/anxiety disorders, insomnia, arrhythmias, or during pregnancy unless directed by a clinician.

Interactions

Do not combine with other stimulants. Use caution with blood pressure meds, heart meds, and medications affected by caffeine (including some anxiety meds).
