My dr checked my magnesium level. It was on the lower end. I have read blood magnesium levels are not the best for accuracy. Who knows. If it is by another alternative test, likely my insurance doesn't pay for it and I cannot afford it out of pocket.
Anyway, I have been taking Magnesium supplement for a few years, yet my level hasn't gone up but a few points.
My dr. has me on magnesium glycinate. Highly absorbable form, without the laxative effect. Best used for deficiencies. He said it is good for my bones and my heart.
As with any supplement, best to have some gauge of your levels and work with a skilled person to supplement. Anything out of balance of too much is not good. So just downing high amount of magnesium isn't good.
My sister in law uses magnesium for leg cramps. Says it works for her.
Nuts have a lot of magnesium.
Anxiety digestive issues can hinder absorption as well. Trick bag
