Hello, I am new to this website. I would appreciate a response from anyone who knows this. IS IT SAFE TO TAKE 500 MG. MAGNESIUM AT ONCE? I DO NOT WANT TO HARM MY BODY. I am taking magnesium for heart palpitations( due to anxiety). I have been taking 250mg. a day. I could not find 400 mg. tablets. Thanks!
