Taking Magnesium, Calcium, and Zinc supplements while on Mirtazapine

I’ve been taking 15mg of Mirtazapine every night for nearly 3 years (I might be coming off in September).

It’s worked great for me, but I grind my teeth at night and have tinnitus (which my be related to my anxiety).

I read that Magnesium, Calcium, and Zinc supplements can help with bruxism and sleep, so I bought some to take as well (and maybe would keep taking it once I come off Mirt).

I was wondering if it’s actually safe to take the supplement while I am still on Mirtazapine or if it causes an interaction or the Mirt not to work?
