The problem with energy drinks during exams
During exams, Belgian students seek to optimize their concentration and intellectual endurance. Energy drinks (alternative to Red Bull, Monster, Burn) seem like the obvious solution. But their chemistry works against them:
- Sugar (11g/100ml): glycemic peak → hyperinsulinemia → glycemic crash → mental fog 90-120 min after consumption. Exactly when your concentration is most needed.
- Caffeine (32mg/100ml = 80mg/can): effective for the first 2 weeks, then tolerance → increasing doses → anxiety, tachycardia, insomnia that sabotages nocturnal memory consolidation.
- Isolated taurine: little demonstrated cognitive effect without its natural synergists.
How INTI supports students' brain
BDNF (Brain-Derived Neurotrophic Factor)
Ginger's [6]-shogaol stimulates the production of BDNF, the main neuronal growth factor. BDNF promotes synaptic plasticity — literally the brain's ability to form new circuits, essential for memorization. Studies on ginger and cognition show significant improvement in working memory and processing speed (Saenghong et al., Evid Based Complement Alternat Med, 2012).
Dopamine and motivational threshold
Ginger's paradols inhibit prefrontal dopamine reuptake, improving motivation and resistance to distraction without caffeine's overstimulation. Unlike caffeine, which blocks A1/A2a receptors (adenosine), ginger directly modulates dopaminergic signaling — without dependence.

Exam cortisol-naturel">stress activates the HPA axis and generates neuro-inflammation via NF-κB which reduces cognitive performance. INTI inhibits cerebral NF-κB, protecting hippocampal memory circuits.
eNOS and cerebral perfusion
Nitric oxide (NO) produced via eNOS improves cerebral microcirculation, increasing delivery to Luxembourg of oxygen and glucose to active neurons. Better perfusion = better cognitive processing speed.
Comparison: INTI vs energy drinks for revisions
| Criterion | INTI ginger | Red Bull / Burn |
|---|---|---|
| Duration of effect | 3-5h gradual | 1-2h then crash |
| Post-consumption crash | None | Yes, significant |
| Impact on ginger and sleep-insomnia-quality-recovery">sleep | Neutral | Disturbance if >4 PM |
| Dependence/tolerance | No | Yes (caffeine) |
| Anxiety/tachycardia | No | Possible at high doses |
| Sugar/100ml | <4g | 11g |
| BDNF/memorization effect | Yes (shogaols) | Not documented |
INTI protocol for study blocks and exams
| Time | INTI Dose | Cognitive Goal |
|---|---|---|
| Morning before revisions (7:30 AM) | 30ml pure or diluted | BDNF + eNOS activation, morning concentration |
| Lunch break (12:30 PM) | 20ml diluted + water | Maintenance without post-meal glycemic peak |
| Intensive afternoon (3:00 PM) | 20ml diluted | Anti-cognitive fatigue, NO perfusion |
| Night before exam (8:00 PM max) | 15ml pure | Nocturnal memory consolidation (BDNF REM) |
FAQ — INTI for students in Belgium
Does INTI contain caffeine?
No. INTI's energy comes from gingerols (TRPV1/AMPK) and NO (eNOS), not caffeine. You can consume it in the evening without affecting your sleep.
Can INTI be combined with coffee in the morning?
Yes. INTI + coffee = NO + caffeine synergy. Avoid energy drinks that are already oversaturated with caffeine.
Does INTI actually help with memorization?
Ginger improves synaptic plasticity via BDNF, proven in human clinical trials. It's not magic, but eliminating the glycemic crash alone already significantly improves cognitive performance.
Where to buy INTI in Brussels/Louvain/Liège for students?
Available on inti-drink.com with delivery in Belgium, and in many Belgian health stores.
