Claire Smith, 37, a nursery practitioner from Richmond, found relief from debilitating irritable bowel syndrome (IBS) symptoms, including chronic bloating, cramps, and fatigue, after incorporating a natural supplement into her daily routine. Smith described her previous eight-year struggle with IBS, which significantly impacted her quality of life and led to anxiety and social isolation.
Previously, Smith managed her symptoms with over-the-counter medications like Imodium, but found they offered little relief and even exacerbated her bloating. Prescription after prescription yielded no significant improvement, leading her to feel disheartened. "It was prescription after prescription with no noticeable difference," Smith stated. She also noted that these medications could cause side effects like nausea, headaches, and further digestive distress, impacting her gut and immune system.
A New Approach to Gut Health
In October, Smith discovered AltruVita's Healthy Gut supplement, advertised on Instagram, and decided to try it. After approximately one month of consistent use, she began to notice a reduction in bloating. Over the subsequent months, the frequency of her cramps diminished, and her energy levels and confidence reportedly improved significantly. "Now, eight months on, my energy levels are up and my confidence has gone through the roof," she said. "I'm cautious of labelling anything a miracle drug – and yes, I do still get the occasional flare-up – but these little supplements have completely changed my life."
AltruVita's Healthy Gut supplement is formulated with curcumin, green tea extract, and Vitamin D, ingredients known to support gut health. The supplement is targeted at IBS symptom relief, and a clinical trial has provided evidence supporting its efficacy.
Clinical Trial Findings
A trial conducted by The Functional Gut Clinic involved 78 participants with mild to severe IBS. Half of the participants took two capsules of AltruVita's Healthy Gut twice daily for eight weeks, while the other half received a placebo. The trial, funded by AltruVita, was double-blinded, meaning neither the researchers nor the participants knew who received the active supplement or the placebo. The study utilized the IBS Symptom Severity Score to track changes in daily bowel movements, abdominal pain, and overall quality of life.
Participants who took the supplement showed a reduction of 54 points on the IBS Symptom Severity Score, which is considered a clinically meaningful improvement. Those in the placebo group experienced negligible improvement. The trial also indicated that the supplement was safe and well-tolerated, with no serious side effects reported.
Potential Mechanisms of Action
While the precise mechanisms are still under investigation, Professor Martyn Caplin, a gastroenterologist at the Royal Free Hospital and lead study investigator, suggested the supplement likely influences the gut microbiome. He explained that curcumin and green tea extract may inhibit the growth of harmful bacteria, creating more space for beneficial bacteria and potentially reducing the production of short-chain fatty acids that can trigger diarrhea or contribute to small intestinal bacterial overgrowth. Registered nutritionist Rob Hobson noted that all three ingredients have plausible mechanisms for supporting gut health and barrier function. "Vitamin D particularly plays an important role in immune regulation and low vitamin D status has been linked with IBS in some people," Hobson added.
Harley Street Nutritionist Kate Cook described the trial results as "encouraging" and a "promising addition to the growing evidence around nutritional approaches to managing IBS," alongside established dietary and lifestyle changes. The challenge of finding effective and palatable long-term solutions for IBS sufferers was acknowledged, making rigorous research in the natural supplement space particularly noteworthy.
