I recommend Korea Yakult probiotics.

You probably know that Korea Yakult is a very famous product. I often order Korea Yakult. Korea Yakult is also available through an app. It's called the Preddit app. On this app, not only Yakult but also various menus like lunchbox milk are sold. Above all, Yakult contains a lot of probiotics. Even a pharmacist told me that drinking Yakult provides more probiotics and is more beneficial. So, I use it often and think that Korea Yakult is the best for probiotics.
