Ranked by research evidence. Compare 35 supplements across 50 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 animalis subsp. lactis BB-12 on short-chain fatty acid production, with effect sizes ranging from small to moderate. Evidence is dominated by in vitro and methodological studies, with limited data from human trials; the most reliable evidence comes from a meta-analysis in older adults showing small beneficial effects on valeric and acetic acid levels.
- Very low evidence5 studies
Across 4 studies (all beneficial, 3 statistically significant), interventions involving Bifidobacterium plantarum or related strains consistently increased short-chain fatty acid production, with effect sizes predominantly moderate (3 moderate, 1 small). However, all evidence comes from in vitro or animal models (diarrheic calves), not human trials. No dose, form, or duration data were reported across studies.
