Probiotic suppliment recs? Do they actually work?

I've been hearing a lot about probiotic supplements lately, especially the gummy versions that claim to help with gut health, bloating, and overall digestion. I’m 20 and pretty curious if they actually work or if it’s just hype.

If you’ve tried probiotics, what was your experience like? Any pros n cons I should know about? And do you have any brand recommendations that are available in India?

Would love to hear real experiences before I buy anything.
