This study is investigating whether a probiotic strain called Levilactobacillus brevis can help improve blood glucose levels and metabolic health. This study aims to determine if this dietary supplement might help regulate blood sugar levels by comparing the effects of high-dose probiotic, low-dose probiotic, and placebo on glucose variability in people with slightly elevated blood sugar levels.

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.  

The recruitment start and end dates are as follows:

Interventional

Intervention Type : Supplement
Intervention Description : Eligible participants will be randomised into one of three arms as below taken by mouth once daily for 6 weeks, followed by a 2-week washout period:Arm 1: Placebo (microcrystalline cellulose)Arm 2: Low-dose probiotic strain (Levilactobacillus brevis) Arm 3: High-dose probiotic strain (Levilactobacillus brevis)

Web-based randomisation with 1:1:1 allocation ratio using random permuted blocks
