Q. Is there a recommended natural cure for graves disease? I've been suffering from graves for a year now and really feel tired of it. I'm thinking of trying some natural medications cause the regular ones are dissapointing so far. Any experience with that??

A. I am not familiar with any natural supplements you can take for graves disease, furthermore, it is an illness where you should be on close monitoring of an endocrinologist, and have them tell you which medications you are allowed to take and what could make the situation worse. If regular treatment doesn't seem to help you much you should go for another check up to see how your thyroid is doing.
