Top picks by evidence
- Low evidence3 studies
Across 3 studies, all reported beneficial effects on antioxidant activity, with effect sizes ranging from small to moderate. Only 1 study, in broiler chickens, showed a statistically significant increase in reduced glutathione activity (P < 0.01). The evidence base is very small and preliminary, with no human trials, consistent dose, or form data available.
- Very low evidence4 studies
Across 4 studies, all reported beneficial effects of Lactobacillus acidophilus L-92 on increased antioxidant activity, with a predominant moderate effect size. The evidence is based entirely on reviews and lacks statistical significance testing, with no specific dose, population, or duration data available. The most commonly observed mechanism involves enhanced antioxidant enzyme activity and biotransformation of polyphenols.
