Is pure encapsulation (magnesium glycinate) good for anxiety?

Is pure encapsulation (magnesium glycinate) good for anxiety? I deal with anxiety which I think is correlated to my stutter. I want a way to release tension and stress my mom body. Before turning fully to medication I am interested in natural alternatives and supplements. Does anyone recommend the pure encapsulation magnesium glycinate brand for anxiety issues? If not what’s a good brand of magnesium glycinate for anxiety to try? Are there any other natural alternatives for anxiety and tension issues?
