Magnesium supplementation & blood tests?

5 Replies

My nutritionist is keen on me taking magnesium. When I take anything other than one or two Neuromag I feel absolutely knackered for days. A recent blood test showed my Magnesium level as 0.94 (0.6-1.0) That seems pretty good to me. Do I really need to supplement?

Do you supplement Vitamin D? If so how much

Plus what was your last vitamin D test result

Lots of us do supplement magnesium (apparently the test is pretty useless that checks levels)

Also recommended is vitamin K2 MK7 for sending excess calcium into bones

Hypo123,

Although your mag blood level is fine a lot of people say that what matters is the magnesium in your cells which isn't easily measureable. There is a school of thought that most of us are magnesium deficient because of magnesium deficiency of soils and that magnesium supplementation can be beneficial. Has your nutritionist said why s/he is keen on you taking it? Perhaps your nutritionist could supply you with a few sample tablets to see how you tolerate them?

Pointless testing magnesium, it will always be in-range because of the way the body handles magnesium. But, that doesn't mean you're not deficient. Yes, you probably should supplement it.

How much magnesium is in the capsules? Does it have to be that brand?

What time of day are you taking it, how many doses are you taking per day, and how big is each dose?

The absorption rate and bioavailability of magnesium supplements differs depending on which you take, plus, those that dissolve in liquid are sometimes better absorbed in the gut than less soluble forms.

If Neuromag doesn't suit you, it might be worthwhile trying out other forms such as:

Magnesium Chelate is highly absorbable by the body and the kind found in foods naturally. This type is bound to multiple amino acids (proteins) and used to restore magnesium levels.

Magnesium Citrate is magnesium combined with citric acid. This may sometimes have a laxative effect when taken in high doses but is otherwise safe to use for improving digestion and preventing constipation.

Magnesium Chloride Oil is a topical oil form of magnesium which can be good for those who have digestive disorders preventing normal absorption from food.

Magnesium Glycinate is highly absorbable, often is recommended for anyone with a known magnesium deficiency and less likely to cause laxative effects.

Magnesium Threonate (I believe Neuromag contains this form) has a high level of absorbability/bioavailability since it can penetrate the mitochondrial membrane, but it's not much good persisiting with it if it has a negative effect on you.

Magnesium Orotate contains orotic acid, which is considered beneficial to the heart.
