Rating (out of 5): 3

Curcumin, the primary active compound in turmeric (Curcuma longa), has been traditionally used in Ayurvedic and Chinese medicine for digestive ailments, including dyspepsia (indigestion). In recent years, scientific research has begun to validate some of these traditional uses. Several randomized controlled trials and meta-analyses have investigated the effectiveness of curcumin in treating dyspepsia and related gastrointestinal disorders, such as functional dyspepsia and irritable bowel syndrome (IBS).

The proposed mechanisms by which curcumin may alleviate dyspepsia include its anti-inflammatory, antioxidant, and gastroprotective properties. Curcumin is believed to modulate gut inflammation, improve mucosal defense, and enhance bile flow, all of which can contribute to improved digestion and symptom relief. A 2019 randomized trial published in BMC Complementary Medicine and Therapies found that turmeric extract was non-inferior to omeprazole (a proton pump inhibitor) in reducing dyspepsia symptoms over a 28-day period. Other clinical studies have also reported significant improvements in symptoms such as abdominal pain, bloating, and early satiety with curcumin supplementation compared to placebo.

However, the overall quality of evidence is moderate. Many studies are small in scale, vary in their formulations and dosages, and sometimes lack long-term follow-up. More large, high-quality trials are needed to firmly establish efficacy and optimal dosing. In summary, curcumin has both traditional and emerging scientific support for dyspepsia, with a moderate evidence base suggesting benefit.
