And our...and other people's research suggests that what we call precision probiotics or next-generation probiotics may be bugs. They don't smell the best, maybe they're not the tastiest bugs, but they may be most effective in colonizing the human gut and positively impact our health in different contexts. We just need to understand how they do it to tailor them to the individual and to make sure that they're safe.”
