Tree-nut allergen: SynoGut contains black walnut hull and is labelled “Contains Tree Nuts.” Do not use it with a tree-nut allergy without a doctor. Facility also processes milk, soy, wheat, egg, peanuts, fish and shellfish. Capsule is gelatin (not vegan).
Credit to SynoGut: unlike many blends, it names all 10 ingredients on the label. The catch is dose transparency — read on.
The proprietary-blend caveat: all 10 ingredients share one 1.5g proprietary blend per 2-capsule serving. Individual amounts are not disclosed, and 1.5g across 10 ingredients averages ~150mg each — a fraction of the doses used in most published studies (e.g. psyllium 5–15g). So it’s a gentle daily blend, not a clinical-strength therapeutic.
| Ingredient | Role | Plain-English notes |
|---|---|---|
| Psyllium (husk) | Soluble fibre | Absorbs water to bulk and soften stool; the most evidence-backed ingredient here. Studied doses (5–15g) are far above a 1.5g blend. |
| Glucomannan (root) | Viscous fibre | Expands with water to support regularity; EU-recognised for normal bowel function at ~4g/day. |
| Prune (fruit) | Natural softener | Sorbitol and polyphenols traditionally support stool softening and motility. |
| Oat bran | Beta-glucan fibre | Supports bulk and regularity; also studied for cholesterol at higher doses. |
| Flaxseed (seed) | Mixed fibre | Soluble + insoluble fibre for bulk and transit; provides omega-3 ALA. |
| Aloe vera (leaf) | Soothing botanical | Traditionally used to soothe the gut lining; “leaf” forms warrant care for sensitive users. |
| L. acidophilus | Probiotic | A well-known probiotic strain; CFU count isn’t disclosed on the label. |
| Apple pectin (fruit) | Prebiotic fibre | Feeds beneficial bacteria; pairs with the probiotic. |
| Bentonite clay | Binding agent | Traditionally used to bind substances in the gut; can also bind minerals/medications. |
| Black walnut (hull) | Botanical — TREE NUT | Traditional “cleansing” herb. This is the tree-nut allergen; avoid with a tree-nut allergy. |
Medication timing: bentonite clay and psyllium can reduce absorption of medicines (and minerals). Take SynoGut at least 2 hours apart from any prescription or OTC drugs, and check with your doctor or pharmacist — especially if pregnant, nursing, under 18, or managing a health condition.
Other ingredients (from the label): gelatin, magnesium stearate, silicon dioxide. The gelatin capsule means SynoGut is not vegetarian or vegan.
