Magnesium

Could someone explain to me please, why magnesium supplementation is recommended? I read somewhere that testing for magnesium deficiency is both unreliable and uncommon. So how do we know we need it and if so, how much?

Thanks.

Thanks for that . But why do people on here recommend supplementing, especially if too much can cause problems?

Many of us are low in most things as we just don't absorb very well due to low stomach acid.... there are many different forms of magnesium and I think it is pretty hard to overdo it as the kidneys deal with excess, but staying within RDA is always the best advice and get tested annually

Magnesium has lots of uses in the body. For one thing, it works with vit D, so essential to take it if you're taking vit D.

It is correct that magnesium testing is not reliable. But, most people are deficient in magnesium because soils are depleted, so we're not getting it from our food. But, as it is water-soluble, any excess is excreted so you don't need to worry about over-dosing.

Normally, it's recommended to take between 350 and 400 mg.

Thanks greygoose. I’ve read the links and they are interesting. I’ll continue to mull it over. Kidney function in older age does deteriorate, like many other things. Magnesium supplementing could possibly put pressure on the kidneys? There’s so much info to balance!

Well, if you took too much, I suppose it could. But, I'm 78 and I've never had a problem taking it.

That’s particularly helpful as I’m 76 next month.

I think its far more likely that most of us are deficient in magnesium than we have too much. I take magnesium glycinate at night to help with sleep.

There are several different types depending on what you want from it. Obviously no one should be taking mega doses but sticking to the recommended amount should be safe.
