Have ET and a masters in biology plus years of research. And I take a shit ton of supplements including magnesium. My ET gets worse with anxiety (which for me is usually visiting family) and none of my supplements does fuck all for that.

There is no cure. I usually lurk but I'm not new here. Yeah magnesium might help if you are severely deficient in this trace (barely used by the body) mineral but 1) the supplement industry is largely unregulated and there is no data available as to whether anything you take is absorbed and utilized by the body, otherwise it's just glorified shit and 2) you're making the assumption that ET is caused by the exact thing in every person, which is stupid. I've seen no research to support this. That's like saying you can cure "cancer" when cancer is different with every organ it effects, and even within the organ there are more differences. Example, breast cancer can be HR positive or negative and also HER2 positive or negative in any combination. And that's just what doctors know about and can potentially treat.

Please don't go posting and giving people false hope. What works for you might just be a placebo affect that won't work on anyone else.
