Best Supplements for Increased Short-Chain Fatty Acid Production
Ranked by research evidence. Compare 33 supplements across 48 papers from the biomedical literature, with effect direction, evidence strength, and dose range for each.
Top picks by evidence
- Low evidence5 studies
Across 4 studies, all reported beneficial effects of Bifidobacterium plantarum (often in combination with other strains) on short-chain fatty acid (SCFA) production, with 3 showing statistically significant findings. The predominant effect size was moderate, though one study reported a small effect. Most studies were in vitro fermentation models or animal-derived fecal samples, and no specific dose or population was consistently reported.
- Very low evidence5 studies
Across 4 studies, all reported beneficial effects of Bifidobacterium animalis subsp. lactis BB-12 (often in synbiotic formulations) on short-chain fatty acid (SCFA) production, with effect sizes ranging from small to moderate. The strongest evidence comes from a meta-analysis of 29 RCTs in older adults that found small beneficial effects on valeric acid (SMD = 0.50) and acetic acid (SMD = 0.62). Only one of the 4 studies reported a statistically significant finding.
