RESEARCH QUALITY ASSESSMENT:
- All studies were randomized, double-blind, placebo-controlled trials, enhancing the reliability of the findings.
- Sample sizes varied from 67 to 100 participants, providing a reasonable basis for statistical analysis.
- Limitations include relatively short intervention periods and the need for longer-term studies to confirm sustained benefits.
- Further research is warranted to explore the mechanisms behind the observed effects and to assess the impact of Bacillus subtilis on diverse populations.
