Bifidobacterium improves anxiety and performance in young divers

This single arm, pilot study, has examined the effects of a Bifidobacterium animalis subsp. lactis BB-12 supplementation in young divers (9.10 ± 1.80 years) under stress conditions. They received 109 CFU/100 g daily for 8 weeks.

Results showed an improvement in cognitive state anxiety, somatic state anxiety and anxiety emotion (p < 0.001, p = 0.003 and p < 0.001 respectively). Moreover, at week 8, the performance of participants under stress was significantly improved (p = 0.019).

These results show therefore that B. lactis BB-12 can reduce anxiety and improve performance in young divers.
