Gut Health
The terrain that everything else depends on.
The gut is where nutrients become you. A compromised gut wall and an imbalanced microbiome show up everywhere — skin, mood, immunity, energy.
L-glutamine for the gut lining, digestive enzymes for breakdown, soluble fibres from sea moss and moringa for the microbiome.

EVIDENCE
The studies behind this
L-glutamine has a landmark Gut (BMJ) RCT in postinfectious IBS-D and a clear tight-junction mechanism. Apple cider vinegar contributes on the metabolic side.
What the studies say
L-glutamine is the primary fuel for enterocytes (gut-lining cells). The most rigorous human trial — Zhou et al. in Gut — showed clinically meaningful improvement in post-infectious IBS-D specifically.
Honest caveatStrong evidence is in post-infectious IBS-D; benefit in healthy adults or other GI conditions is less established.
- 01RCT
Randomised placebo-controlled trial of dietary glutamine supplements for postinfectious irritable bowel syndrome
Zhou Q, Verne ML, Fields JZ, et al. · Gut (BMJ) · 2019 · n=106
“Oral glutamine therapy significantly reduced IBS-Symptom Severity Score (≥50-point reduction) in patients with postinfectious IBS-D and increased intestinal permeability.”
Plain EnglishLandmark RCT: oral glutamine produced clinically meaningful symptom improvement in postinfectious IBS-D.
- 02MECHANISTIC STUDY
Glutamine Restores Tight Junction Protein Claudin-1 Expression in Colonic Mucosa of Patients With Diarrhea-Predominant IBS
Bertrand J, Ghouzali I, Guérin C, et al. · JPEN. Journal of Parenteral and Enteral Nutrition · 2016
“Glutamine restored colonic claudin-1 tight-junction protein expression in IBS-D patients, providing a mechanistic basis for the symptom improvements observed clinically.”
Plain EnglishMechanistic study: explains how glutamine works — by restoring tight-junction proteins in the gut lining.

What the studies say
ACV's clearest data is on post-meal glucose response and lipid profile — modest but reproducible effects. Weight-loss claims are smaller and noisier than the marketing implies.
Honest caveatDental enamel and oesophageal irritation are real risks at high concentrations. Always dilute, never sip neat.

The effect of apple cider vinegar on lipid profiles and glycemic parameters: a systematic review and meta-analysis of randomised clinical trials
Hadi A, Pourmasoumi M, Najafgholizadeh A, et al. · BMC Complementary Medicine and Therapies · 2021

Effect of Apple Cider Vinegar Intake on Body Composition in Humans with Type 2 Diabetes and/or Overweight: A Systematic Review and Meta-Analysis of RCTs
Various · Nutrients · 2025

Plain EnglishSmall but real reductions in body weight and BMI in T2D / overweight populations.

Questions
- Probiotic or prebiotic?
- Both. Prebiotics feed the bacteria you already have; probiotics introduce specific strains. Most people benefit from prebiotic-rich whole foods first.
