Is It Supposed to do This?

A little info before I ask my question. I have noticed I am an emotional individual, prone to mood swings, I get aggitated quickly, and I can be “bitchy” I guess would be the beat way to describe me sometimes. Well I ordered “M” and began taking it, I noticed I wasn’t as stressed out, or as moody as I was since I’ve been taking it. Is that what “M” is supposed to do?
