Anxiety for a couple hours after taking magnesium bisglycinate?

Hello friends ♡

Today I decided to try magnesium bisglycinate as suggested by a handful of folks on here. For about 2-3 hours afterward I experienced an elevated heartrate (went from 80-85 to 90-95ish) and diarrhea

I saw some posts claiming bad reactions could come from fillers. The only one I could find listed on the bottle was hypromellose.

Has anyone else experienced this? Should I stop trying magnesium? Potentially try a different product? Any other advice?

For reference, I was using the bioschwartz brand one (hopefully its ok to share that), it was the first result on amazon for me

my other meds im on at the moment is 80mg extended release propranolol, and 10mg generic zyrtec

Thank you ♡
