Just going to say the biggest must know here, these chews are super hard and not easy to chew, unless you got the chompers of a bulldog, by Gad! I take magnesium for really bad thigh cramps (painful and super long running- not fun at all :/) Its important i can get my Mg in quickly and effectively. I was hoping these would be good like this, being they were spendy and in in being a quick ingest- but they also faltered on bringing the much needed Relief I was hoping ( more like begging when im in the episode! Geez they suck) I make sure to get the Mg Cylinate as it works best for muscle cramping, these chews say they contain both forms of Mg, but from the no relief I felt, if they do, must be quite a minute amount of Mg that does do the trick for muscle cramping. Ok, hope this helps! Save yourself from getting early dentures and maybe go for a capsule or liquid variety, I love sweet things like this, but this chokable chew more dangerous than fun, in my book at least! Best and betters to you and yours and thanks for reading!
