Excellent! This works!

After I had COVID, it suffered from "long COVID". I thought that wasn't a real thing until I had it. It's not COVID. It's lingering side effects that nobody understands, so they call it "long COVID". A symptom I had was confusion and fuzzy thinking. My wife found this and within two weeks my confusion and fuzzy thinking were gone. We can argue about why they left, but I firmly believe it was this stuff. The timing was just too good. Also, I got better slowly over the second week of taking it. It makes sense to me to give this credit.

Excellent!

Hello? This magnesium is going to help with sleep!? That's everyone says in the review and I am so excited to try! I've been having really bad sleep quality after contracted the c word virus and I am definitely looking forward to try this product! The ingredients look clean. I will update my results.
