Probiotic supplementation reduces hyperactivity and improves academic performance in adults with ADHD
A double-blind RCT found that a multi-strain probiotic supplement taken daily for three months significantly decreased hyperactivity, improved gastrointestinal symptoms, and enhanced academic performance in college students with ADHD. Age was a significant predictor, with younger participants showing greater overall benefits.

Probiotic supplementation reduces hyperactivity and improves academic performance in adults with ADHD The current body of evidence comprises 1 study, including 1 randomized controlled trial. EvidenceHub rates the overall confidence at 42/100 (low).
The Claim
Probiotic supplementation reduces hyperactivity and improves academic performance in adults with ADHD
This conclusion is most relevant to: College students with ADHD.
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Exploring the impact of probiotics on adult ADHD management through a double-blind RCT. (Scientific reports, 2024) —
How It Works
The proposed biological pathway:
- ▸Probiotic supplementation alters gut microbiota composition
- ▸Gut-brain axis modulation affects hypothalamic-pituitary-adrenal axis activity
- ▸Reduced cortisol levels (negative correlation with attention/impulsivity symptoms)
- ▸Result: Decreased hyperactivity and improved academic performance
Who Might Benefit
Evidence fit by population:
- ▸College students with ADHD
Recommended Dose
Daily multi-strain probiotic supplement (specific dose not reported in abstract)
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Specific probiotic strains and doses not detailed in abstract
- ▸Single study with limited generalizability to non-college adult populations
- ▸No long-term follow-up data provided
Frequently Asked Questions
What type of probiotic was used in this study?▼
The abstract mentions a multi-strain probiotic supplement but does not specify the exact strains or dosage.
How long did the intervention last?▼
Participants took the probiotic or placebo daily for three months.
Did the probiotic affect all ADHD symptoms equally?▼
The probiotic significantly decreased hyperactivity and improved academic performance, but a negative correlation was found between fingernail cortisol and symptoms of attention and impulsivity, suggesting differential effects.
Who was eligible for this study?▼
The study included college students with ADHD, and age was identified as a significant predictor of benefit.
