Ginger and Irritable Bowel (IBS): Scientific Approach
Summary: Ginger acts on 3 key mechanisms of IBS: prokinetics (gastric emptying +25%), intestinal anti-inflammation (NF-κB), and modulation of the microbiota (Lactobacillus ↑, Clostridium ↓). INTI adds curcumin — intestinal anti-inflammatory validated in IBS.
IBS: a multi-factorial disorder
Irritable bowel syndrome affects 10-15% of the population and involves:
- Dysmotility — transit too fast (diarrhea) or too slow (constipation)
- Visceral hypersensitivity — amplified perception of distension
- Low-grade inflammation — activated mast cells in the mucosa
- Dysbiosis — imbalance of the intestinal microbiota
- Gut-brain axis — stress → symptoms → anxiety → cycle
Actions of ginger on IBS
1. Regulation of motility
Ginger is prokinetic (accelerates slowed transit) AND antispasmodic (calms excessive spasms). It normalizes intestinal motility rather than forcing it in one direction. Mechanism: modulation of 5-HT₃/5-HT₄ receptors — the same ones targeted by alosetron (IBS drug).
2. Mucosal anti-inflammation
NF-κB suppression → reduction of activated mast cells → less intestinal histamine and serotonin → reduction of pain and visceral hypersensitivity.
3. Modulation of the microbiota
Wang 2019: ginger promotes Lactobacillus and Bifidobacterium while reducing Clostridium perfringens → more balanced microbiota → less gas and bloating.
4. Gut-brain axis
Reduced gut inflammation → fewer pro-inflammatory signals to the brain via the vagus nerve → reduced IBS-related anxiety.
Sugar and SII: the enemy
Sugar is a major trigger for IBS:
- Fructose → colonic fermentation → gas → bloating
- Insulin peak → motility disturbance
- Feeds gas-producing bacteria
A shot of ginger with 33g of sugar/100ml is a liquid FODMAP. For an irritable bowel, this is the opposite of what is needed.
INTI — 1.1g of sugar/100ml. Prokinetic + anti-inflammatory + prebiotic. Without excessive fermentation.
Does ginger help irritable bowel syndrome?
Ginger acts on several mechanisms of IBS: it normalizes intestinal motility (prokinetic + antispasmodic), reduces mucosal inflammation (NF-κB), and rebalances the microbiota. It's crucial to choose a shot without added sugar, as sugar ferments in the colon and worsens IBS symptoms. INTI contains 1.1g of sugar/100ml and adds curcumin — validated intestinal anti-inflammatory.
⚠️ IBS requires a medical diagnosis (Rome IV criteria). Consult a gastroenterologist. Ginger is a supplement, not a treatment.
