Abstract
Probiotic use is examined for its associations with psychological, cognitive, and gastrointestinal outcomes.
- Research has shown mixed results regarding the health benefits of probiotics.
- The gut-brain axis may provide a basis for probiotics to influence mental and cognitive health.
- Evidence of these associations is inconsistent, especially in community samples.
- Delivery method, whether through supplements or fermented foods, may play a role in the observed outcomes.
