Sadieci, If you read my post again, you'll notice that I did NOT recommend that you take magnesium!!! Too much magnesium can make MG worse. Most people get enough from foods (i.e., nuts).

You don't want to mess around with electrolytes. First, if any of them are out of the normal range, that can reflect any number of different disease states (i.e., Addison's disease). Causes for an imbalance should be sought by a internist or an endocrinologist (preferable).

Too much or too little potassium, magnesium and calcium can make MG worse, so please don't go playing around with taking them until you know if you have a problem!

Is there a doctor you can go to?

B12 won't hurt you, but I hope you got the methylcobalamin instead of the cyanocobalamin.

Does that make sense?

And when you're trying to see what makes something better (or worse), it's best to take only one thing at a time to know which one is doing that!
