DO I HAVE MAGNESIUM DEFICIENCY AND, IF SO, HOW MUCH MAGNESIUM SHOULD I TAKE?
1) How do I know if I am deficient in magnesium?
There are some “classic” magnesium-deficiency symptoms that are a very clear sign of low levels of magnesium in the tissues: if you have any of these, you can bet your bottom dollar that you wouldn’t do yourself any harm (see warnings below for exceptions) if you went out and got yourself a magnesium supplement and some magnesium-rich food and water pretty pronto.
These are:
· any kind of muscle cramping, especially the kind that wake you up in the middle of the night (what Americans call a “charly horse”), trying to work out the cramps in your calves or toes that turned up when you innocently stretched;
· a stiff neck or shoulders;
· twitching eyelids;
· arrhythmias (although these can have different causes, an irregular heart beat can also be caused by a lack of magnesium and/or an abundance of calcium;
· general tiredness and being easily fatigued, especially during sport.
The best magnesium supplement I have tried so far (and, believe me, I have tried a lot of different kinds) is this one:
