Executive Summary

This clinical study investigated the effects of Broth + Co Beef Bone Broth Powder in Australian adults experiencing lower gastrointestinal symptoms. Participants consumed the bone broth daily for 8 weeks, following a 3–4 week run-in period, as part of a 12-week single-arm clinical study.

Key Findings

Participants experienced statistically significant improvements in:

• Lower gastrointestinal symptoms, including constipation, diarrhoea, urgency, flatulence and abdominal pain.
  
• Upper gastrointestinal symptoms, including indigestion, heartburn, regurgitation and nausea.
  
• Stool consistency, frequency and regularity.
  
• Quality of life, including emotional wellbeing, energy, sleep, physical functioning, diet and social interactions.
  
• Intestinal permeability (gut barrier function) in participants with elevated baseline levels. Lactulose and Mannitol Recovery improved by 33%, while the Lactulose:Mannitol Ratio improved by 38%.
  

Food intolerances also improved during the study. While 83% (25/30) of participants reported food triggers at the beginning of the study:

• More than 80% regained tolerance to FODMAP-containing foods.
  
• Approximately one-third regained tolerance to gluten, dairy, acidic foods, spicy foods, eggs and fried foods.
  

Background

Broth + Co Beef Bone Broth Powder is made from 100% Australian grass-fed and finished beef bones and connective tissue, providing a natural source of protein, collagen-derived amino acids, minerals and naturally occurring compounds found in bone broth.

The powder is produced using a gentle freeze-drying process, helping preserve the nutritional integrity of the slow-cooked bone broth while providing a convenient shelf-stable format.

Bone broth naturally contains amino acids including glycine, proline and glutamine, which are important components involved in normal connective tissue structure and are being investigated for their potential role in supporting digestive health and gut barrier function.

Study Objective

To evaluate the tolerability and effectiveness of Broth + Co Beef Bone Broth Powder in Australian adults experiencing gastrointestinal disturbances.

Study Design

• Australian single-arm clinical study
  
• 30 adults with moderate lower gastrointestinal symptoms
  
• 12-week duration (3–4 week run-in plus 8-week intervention)
  
• Participants consumed Broth + Co Beef Bone Broth Powder daily
  
• Outcomes assessed using validated gastrointestinal questionnaires, the Bristol Stool Chart, IBS Quality of Life Questionnaire and intestinal permeability testing.
  

Conclusion

This study found that daily consumption of Broth + Co Beef Bone Broth Powder was associated with significant improvements in gastrointestinal symptoms, gut barrier function, stool patterns and quality of life in adults experiencing digestive discomfort.

These findings suggest that Broth + Co Beef Bone Broth Powder may support digestive wellbeing and gut barrier function as part of a healthy, balanced diet. Further research, including larger controlled clinical trials, is warranted to confirm these findings.
