Please recommend a probiotic that won't cause resistance.

I've been taking probiotics, but after taking them consistently for about a month, the effect started to wear off, maybe because I developed a tolerance...

I've just been taking Lacto-Fit, which everyone knows, but seeing this makes me wonder if I should try something different...

I used to be able to go to the bathroom just by taking one Lacto-Fit, but now I have to take two to see any effect 💧💧

Is it common for resistance to develop like this?

Or maybe it's just me...

If you happen to have any probiotic recommendations, please let me know too!! 👀

I'm planning to buy it during the Olive Young sale!
