Medical education in Belgium: a high-risk environment for overload
In Belgium, medical training lasts 6 years (Bachelor) + 1–5 years of specialization (Master/Assistantship). Nursing (Bachelor 3 years) involves intensive clinical internships from the first year. These programs are recognized as the most demanding:
- 40 to 60 hours of work per week (classes + internships + study)
- Night shifts from the 4th–5th year (medicine)
- Chronic exam stress (MCQ, OSCE, clinical evaluation)
- Early exposure to suffering, death, and emergency situations
- High prevalence of academic burnout (20–30% according to studies)
The energy drink trap in medical education
1. Alternative to Red Bull, Monster, and false energy
A Belgian study (KULeuven, 2021) showed that 65% of medical students regularly consume energy drinks during exam sessions. Red Bull (11g sugar/100ml), Monster (11.4g): each can provides ~27–30g of sugar. The pattern is always the same: coffee + energy drink → dopamine/caffeine peak → crash 90 minutes later → new energy drink → cycle of dependence.
This cycle generates:
- Chronically high cortisol (repeated HPA activation)
- Suppressed BDNF in the hippocampus (impaired working memory)
- NF-κB activated in cortical neurons (brain fog)
- Worsened sleep quality (late caffeine + night sugar)
2. BDNF and working memory: the central challenge
BDNF is essential for long-term potentiation (LTP) — the neuronal mechanism of memorization. Chronic cortisol and sugar suppress BDNF in the hippocampus, which precisely affects working memory and learning ability. Ginger stimulates BDNF and TrkB (its receptor) — directly supporting synaptic plasticity during intensive learning periods.
3. Cortisol and academic performance
Moderately elevated cortisol improves short-term alertness (eustress effect). But chronic cortisol (>2–3 weeks) damages episodic memory, reduces hippocampal volume, and suppresses BDNF synthesis. 6-Gingerol inhibits 11β-HSD1 (the enzyme that converts inactive cortisone into active cortisol) — thereby lowering cellular exposure to cortisol without blocking the acute stress response.
Comparison of drinks for medical/nursing students
| Drink | Sugar /100 ml | Cognitive impact | BDNF / Cortisol |
|---|---|---|---|
| INTI ginger-shot-uk-organic-concentrate-guide">best ginger shot | <4 g | ✅ NF-κB↓, memory supported | BDNF↑, Cortisol↓ |
| Red Bull | 11 g | ❌ Crash 90 min, BDNF↓ | Cortisol↑, BDNF↓ |
| Monster Energy | 11.4 g | ❌ ginger anxiety, trembling, crash | Cortisol↑↑, BDNF↓↓ |
| GIMBER concentrate | ~35 g | ❌ Glycemic peak → brain fog | Cortisol indirectly↑ |
| Coffee + sugar (3 cups) | ~8 g | ⚠️ Caffeine useful + sugar harmful | Variable |
| Black coffee + water | 0 g | ✅ Alertness without sugar | Neutral |
Protocol for exam sessions and intensive internships
| Time | Recommendation | Cognitive effect |
|---|---|---|
| Morning | INTI shot + black coffee | BDNF↑ + caffeine: cognitive synergy without sugar |
| Study block (3h) | Water + diluted INTI halfway | Cortical NF-κB↓, attention maintained |
| Meals | Water / unsweetened herbal tea | Avoid post-meal crash (detrimental to study) |
| Night shift (internship) | INTI shot + black coffee (once) | Stimulation without energy drink cycle |
| AVOID | Repeated energy drinks (cortisol/crash cycle), sweetened GIMBER, sodas — reduce BDNF and sleep quality | |
❓ FAQ — Medical students and ginger
Does ginger directly improve memorization?
Indirectly yes — via BDNF↑ (synaptic plasticity) and NF-κB↓ (neuroinflammation). Animal studies and some human studies show improved working memory and processing speed with ginger supplements.
Does ginger interact with ADHD medication (Ritalin) that students sometimes use?
No documented interaction between ginger and methylphenidate. INTI can be complementary to ADHD treatment.
Can I take INTI before an exam?
Yes. Ideally, INTI + black coffee 60 minutes before the exam: ginger prepares the brain (BDNF peak), caffeine maintains alertness. Avoid an empty stomach if you are sensitive — dilute the shot in 200 ml of water.
Are "zero sugar" energy drinks a better alternative?
Less bad in terms of glycemia, but sweeteners (acesulfame-K, sucralose) disrupt the microbiome and can affect AMPK. INTI without sweetener remains preferable for the long term.

For those who study to care — and deserve better than Red Bull.
