What magnesium do you take?

There are SO MANY different forms of magnesium and I have read so many different posts praising different forms. I’ve been taking Oxide and I am realizing that it may not be the best option. I was originally told to start taking 300-500mg of magnesium (and vitamin b2) by my neurologist but now I am realizing there are so many other benefits than just neuro, especially in other forms.

What type of magnesium do you take? Specifically, what brand (and share a link for bonus points). I am looking for high quality options and am willing to spend what I need for the best option. Right now I am looking at Glycinate and L-threonate but am open to recommendations before I discuss with my doctors. Thanks!
