So, I got some magnesium chloride powder to take as a supplement a year to three ago. I tried it a few times, but it didn't have positive effects, particularly, and it did have negative ones (not severe negative ones). Plus, it was super bitter. I think I thought I was taking the right amount based on some instructions I had read, but on further research and trying it again, today, I think I was taking too much, and that's why it wasn't helping.
So, I tried an amount like that, and it was a very different experience. It felt healthy, and it actually tasted good (kind of like milk), instead of super bitter! So, if it's quite bitter, you're probably taking too much.
