Magnesium (Mg) - urine


Indications:

Magnesium is an essential mineral that is involved in many enzyme systems throughout the body. It is present in cells with potassium where the balance across the cellular membranes with extracellular sodium and calcium is important. It is also required, with B vitamins, for the release of energy from carbohydrates and fat.

It is likely that mild magnesium deficiencies are widespread in the community due to the extensive consumption of highly processed foods and a poor intake of fresh vegetables, this can result in fatigue, muscle cramps, pain and weakness (magnesium is required for muscle relaxation), cold extremities, pre-menstrual syndrome, period pains, migraines, insomnia, anxiety and nervousness, constipation and others. The malnourished, alcoholics and diabetics will often have quite severe magnesium deficiencies and patients with osteoporosis, joint problems, psychiatric symptoms, high blood pressure or heart disease may benefit from magnesium supplementation (all administered under medical supervision).

Because magnesium is required for vitamin B1 metabolism, B vitamin levels should be considered in conjunction with magnesium.

Chlorophyll, the green colouring material in plants, contains magnesium, therefore good dietary sources of magnesium include all green vegetables (the greener the better). It is also found in whole-grain cereals, nuts, seeds and beans, bananas, meat, milk, seafood and cocoa. In hard water-areas tap water is also an important source of magnesium.

Magnesium is a safe supplement to take, although it can result in diarrhoea (in which case spread the dose over a longer period of time). An average daily intake of 400-800mg, depending on individual circumstances, is probably required to maintain an adequate magnesium status. The presence of selenium and vitamin E is also required for the magnesium is to be absorbed.

Plasma and hair magnesium levels are good indicators of magnesium status, as is the magnesium retention test (24hr urine magnesium levels before and after intramuscular magnesium injections), although this is not as convenient for the patient. A plasma level of magnesium is not a reliable indicator because it is the intracellular levels that are of importance. Magnesium levels on a hair mineral analysis report can be affected by external factors.

Oral magnesium repletion can often take a long time and some patients only respond to intra-muscular magnesium injections.

Clinical Indications:

Fatigue, muscle cramps, pain and weakness (magnesium is required for muscle relaxation), cold extremities, pre-menstrual syndrome, period pains, migraines, insomnia, anxiety and nervousness, constipation and others.

The malnourished, alcoholics and diabetics will often have quite severe magnesium deficiencies and patients with osteoporosis, joint problems, psychiatric symptoms, high blood pressure or heart disease may benefit from magnesium supplementation (all administered under medical supervision).
