|---|---|---|---|---|
| Probiotic Anxiety Randomized Trial | Anxiety is a prevalent non-motor symptom of Parkinson's disease (PD), yet treatment options remain limited. | 2 | Lam JST (2026) | Probiotic supplementation for anxiety symptoms in people with Parkinson's disease: a randomized, double-blind, placebo-controlled trial. |
| Probiotic Anxiety Randomized Trial | Both the probiotic (n = 30) and placebo (n = 31) groups showed significant within-group improvements on the Parkinson Anxiety Scale, with no significant between-group differences. | 2 | Lam JST (2026) | Probiotic supplementation for anxiety symptoms in people with Parkinson's disease: a randomized, double-blind, placebo-controlled trial. |
| Probiotic Anxiety Randomized Trial | Probiotics and postbiotics are gaining attention for their potential to modulate mood and stress via microbiome-related mechanisms, but human evidence remains limited, particularly in non-clinical populations. | 2 | Day R (2026) | A Randomised, Double-Blind, Placebo-Controlled Trial of Probiotic and Postbiotic Strains in Healthy Adults with Self-Reported Anxiety: Effects on Mood, Vitality, Quality of Life and Perceived Stress. |
| Probiotic Anxiety Randomized Trial | Objectives : We aimed to assess the effects of a two-strain combination of live microorganisms alongside a two-strain combination of heat-treated inactivated microorganisms on outcomes associated with anxiety, mood, perceived stress, and quality of life in healthy adults experiencing mild stress. | 2 | Day R (2026) | A Randomised, Double-Blind, Placebo-Controlled Trial of Probiotic and Postbiotic Strains in Healthy Adults with Self-Reported Anxiety: Effects on Mood, Vitality, Quality of Life and Perceived Stress. |
| Probiotic Anxiety Randomized Trial | Conclusions : Supplementation with either the dual-strain live or inactivated formulations was associated with significant improvements in the vitality domain of the SF-36, whilst participants receiving the inactivated formulation demonstrated lower perceived stress and improved social functioning compared to baseline. | 2 | Day R (2026) | A Randomised, Double-Blind, Placebo-Controlled Trial of Probiotic and Postbiotic Strains in Healthy Adults with Self-Reported Anxiety: Effects on Mood, Vitality, Quality of Life and Perceived Stress. |
| Probiotic Anxiety Randomized Trial | Background: Subclinical psychological symptoms-such as low mood, perceived stress, and poor sleep-affect a large portion of the population and can impair quality of life despite remaining below clinical thresholds. | 2 | Day R (2026) | A Randomised, Double-Blind, Placebo-Controlled Trial of Probiotic and Postbiotic Strains in Healthy Adults with Self-Reported Anxiety: Effects on Mood, Vitality, Quality of Life and Perceived Stress. |
