Diary of Unknown Symptoms

Mystery of the Internal Vibration

Entry for August 14, 2006

I start the day organizing the myelin sheath building vitamins. B1, B6, B12, folate, vitamin C, D, and E, Magnesium, Omega 3 and Lecithin.

Here’s what I find on magnesium absorption:

Best taken: At bedtime with calcium in the ratio of one or two parts calcium to one part magnesium. Most absorbable forms are magnesium orotate and amino-chelated magnesium. Magnesium gluconate and magnesium chloride are less effective but can be taken orally.

The process of digestion and absorption of magnesium is very similar to that of calcium. The suggested ratio of intake of these two vital nutrients is about 2:1, calcium to magnesium. Magnesium also requires an acidic stomach environment for best absorption, so taking it between meals or at bedtime is recommended. Meals high in protein or fat, a diet high in phosphorus or calcium (calcium and magnesium can compete), or alcohol use may decrease magnesium absorption.

Usually, about 40-50 percent of the magnesium we consume is absorbed, though this may vary from 25-75 percent depending on stomach acid levels, body needs, and dietary habits.

The levels of magnesium used by physicians are commonly in the range of 600-1,000 mg.; however, the researchers in the kidney stone studies used only 200-300 mg. of supplemental magnesium oxide. Calcium and magnesium are both alkaline minerals, so they are not taken with or after meals, as they can reduce stomach acid as well as being absorbed poorly when taken with food. They are absorbed better when taken between meals or on an empty stomach, especially with a little vitamin C as ascorbic acid.

Many calcium-magnesium combinations are formulated with hydrochloric acid and vitamin D to aid the mineral absorption. And taking them before bedtime may be very helpful in increasing utilization of both these important minerals and lead to a sleep-filled night.

The best forms of supplemental magnesium seem to be the ones chelated to an amino acid (magnesium glycinate, magnesium taurate) or a krebs cycle intermediate (magnesium malate, magnesium citrate, magnesium fumarate). These forms seem to be better utilized, absorbed, and assimilated. Try to stay away from inorganic forms of magnesium like magnesium chloride or magnesium carbonate because they may not be absorbed as well and may cause gastric disturbances.

The magnitude of increased absorption with true amino acid chelates is biologically profound. Comparing a magnesium amino acid chelate to magnesium oxide (a typical salt found in many supplements) the amino acid chelate had 9 times the absorption as the oxide. This study compared the use of the single mineral. If another inorganic mineral were given at the same time, such as calcium carbonate, the usual effect would be no reduction of the amino acid chelate, but a further 70-80% reduction of magnesium absorption from the oxide form. The net effect on absorption of chelated to inorganic magnesium, if two or more inorganic minerals are taken, can be 20-30 fold greater absorption or more of the amino acid chelate.

Magnesium-containing products are either used in treating a primary or secondary magnesium deficiency or are given for prophylaxis as food supplement. Various inorganic (oxides, chlorides, sulfates and carbonates) and organic (citrates, aspartates) magnesium compounds are available for oral administration.

A comparison of the magnesium content of food as stated in tables of nutritional values and the actual analytical values showed that food contains less magnesium than reported in the literature. This means that a deficiency may arise even when the calculated intake is sufficient. Also, food processing, such as polishing rice or cooking fresh vegetables, can lead to loss of magnesium. However, insufficient supply due to nutrition is only one of many causes of magnesium deficiency.

Those suffering from chronic fatigue syndrome also seem to do better with magnesium given by injection. This may be due to the superior absorption of injectable magnesium or because high concentrations in the body are necessary for maximal therapeutic effects.
