A patient who hadn’t felt good for many years came in the other day and told me an osteopathic physician she had gone to for manipulative treatment had suggested she take a basic 400mg magnesium supplement and it had been life-changing for her.

She handed me a photocopied little essay the osteopath had written about the many functions of magnesium in the human body and the symptoms of deficiency.

All her vague gastrointestinal symptoms were gone, her skin had cleared, her energy level had improved and she felt more clearheaded.

“What was your level?” I asked.
