The widely popular form of the magnesium – magnesium oxide – is preferred by dietary supplement manufacturers as it is 70 per cent element magnesium and the rest 30 per cent carrier – oxide. However, less than 5 per cent of magnesium oxide could be absorbed by the human body.
The commonly provided daily dose of the magnesium oxide in supplements is 400 milligrams per day. If the person takes it, then just 16 milligrams of the magnesium oxide will be absorbed by the body. The other forms of magnesium in dietary supplements like malate, glycinate, citrine provide 30 per cent elemental magnesium and just about 40 per cent is absorbed. Thus just about 200 milligrams if a 400 milligram magnesium supplement becomes absorbed by the human body.
The pharmaceutical companies that make mineral supplements very often list on the label for the total amount of mineral complex, but not the elemental amount if calcium or magnesium which are bulky minerals.
Thus today consumers have little chance of knowing whether they are getting the amount of magnesium and calcium that they really need. In fact, magnesium oxide should not even be sold. While choosing the supplements to take, you have to determine how much elemental magnesium and calcium is in the product you are going to purchase.
In fact, calcium is necessary, but still over promoted mineral. Its widely acclaimed function is to maintain your bones because it is the main mineral in the skeleton.
If you ask any physician, pharmacist or dietician about how much supplemental calcium is necessary for preventing age related bone loss, they are more likely come up with the 1200 milligrams a day.
However, this number was produced by a government panel of experts that claimed that 1200 milligram recommendation was the combination of the diet together with supplements.
A lot of dietary supplement manufacturers and doctors provide full 1200 milligrams of calcium without any regard for the dietary intake which is about 800 milligrams a day.
For example, Japanese women traditionally consume just 400 milligrams of calcium on everyday basis and have fewer hip fractures. It is the main reason why mineral supplements are taken.
In fact, postmenopausal women require just 400 mg of calcium from supplements in order to meet the recommended daily intake.
Excessive intake of the calcium could produces kidney stones, calcified arteries, hypertension, calcified heart valves, muscle spasms and even constipation.
However, even 400 milligrams of supplemental calcium will not prevent osteoporosis. There was a research where the data concerning the fact that bone density prevents fractures were investigated. It has been determined that in countries with high bone mass density, the elderly have much higher level of fracture rates.
The daily products industry influenced government health authorities to over promote calcium and the dieticians, doctors, pharmacists as well as supplements manufacturers went along the false way.
