Aegle marmelos (Bael) fruit extract · standardised to gallotannic acid + marmelosin
Gevalin®: dual-mechanism Aegle marmelos (Bael) extract buffering gastric acid and supporting the mucosal barrier. Distributed in Türkiye by Biontera.
Gevalin® is a proprietary extract of Aegle marmelos (Bael) fruit ; used for centuries in traditional Indian medicine ; standardised to gallotannic acid and marmelosin, developed for formulations targeting the gastric-comfort research area.
The published mechanism-of-action file describes two complementary actions: a buffering (antacid-like) effect that balances gastric pH, and a mucosal protective barrier supported by increased mucus secretion.[1] In a 7-day observational case study of ten participants taking 250 mg daily, improvements were reported in symptom scores for acidity, reflux, bloating and bowel regularity.[2]
The literature reports a 42–44% risk of symptomatic ulcer or gastrointestinal bleeding in chronic NSAID users; proton-pump inhibitors deliver strong acid suppression, but questions around their long-term use have driven formulation interest toward naturally sourced supportive ingredients. Aegle marmelos, of the Rutaceae family, bears fruit rich in tannins and coumarin derivatives.
Gevalin®'s mechanism file assembles in-vitro and observational data along three axes: acid-neutralising capacity, increased mucus secretion, and mucosal surface protection. This dual mechanism is a distinctive profile for gastric-comfort formulations seeking a physiological approach not based on acid suppression alone.
A dual-mechanism profile combining gastric pH balance with mucosal barrier support, documented in a published file. Mechanism review + in-vitro data
Marked improvement in gastrointestinal symptom scores over 7 days alongside dietary and lifestyle adjustments. Observational, single-arm · n = 10 · 250 mg/day · 7 days
Every shipment can be delivered with a 12-item technical documentation file on request:
Per the published mechanism file, the extract both buffers gastric acid to balance pH and increases mucus secretion, supporting a protective barrier over the gastric mucosa. The two actions are complementary.
Chewable tablets, effervescents, capsules and sachets; its sensory profile suits chewable formats.
The extract is standardised to gallotannic acid and marmelosin markers, delivered with a lot-based CoA.
The mechanism file (Ver. 03) and case study are shared in full text after an NDA; request them together with samples.
