Heyndrickxia coagulans as a next-generation probiotic: current evidence and future perspectives

Area of Science:

• Microbiology and Probiotics
• Gastroenterology
• Metabolic Health
• Neuroscience

Background:

• Heyndrickxia coagulans is a spore-forming probiotic known for exceptional heat and acid tolerance.
• Its spore form ensures high survivability, retaining 73% viability after microwave treatment at 260 °C.
• The bacterium exhibits dual lactate fermentation pathways and adaptable ATP synthesis.

Purpose of the Study:

• To review the unique biological characteristics of H. coagulans.
• To summarize clinical evidence for its therapeutic potential in various disorders.
• To explore the mechanisms underlying its efficacy and identify future research directions.

Main Methods:

• Systematic review of existing literature on H. coagulans.
• Analysis of clinical evidence for metabolic, gastrointestinal, and neuropsychiatric applications.
• Examination of toxicological data and strain-specific effects.

Main Results:

• H. coagulans demonstrates efficacy in type 2 diabetes, NAFLD, constipation, IBS, depression, and Alzheimer's disease.
• Mechanisms include SCFA production, TLR4/MyD88/NF-κB pathway modulation, and oxidative stress suppression.
• Strain-specific effects noted: MTCC 5856 reduces abdominal distension; Unique IS-2 alleviates anxiety.

Conclusions:

• H. coagulans possesses significant therapeutic potential across multiple health domains.
• Strain specificity and limited intestinal colonization are key considerations.
• Further research, including large-scale trials and synbiotics, is needed to optimize its clinical use.
