As a spore-former, it is inherently shelf-stable and designed to survive gastric acid transit
Short-chain fatty acids affect immune cell function, leading to changes in the levels of released cytokines and reactive oxygen species
There is a chance that peptides besides GLP-1s will eventually be demonstrated to provide health outcome benefits as seen in rodent pre-clinical models
Why indeed would anyone take such a chance
