Dr. Wong's Essentials® Magscorbate® is a blend of our own "chelated" magnesium using just enough Vitamin C to assure good absorption of the mineral, while providing the full load of elemental mineral stated on the label: 510 mg of Magnesium. We chose to use the more expensive Vitamin C instead of the cheaper Citric Acid as the blending agent because Vitamin C has health benefits to your body that citric acid does not have.
Magnesium is an essential mineral nutrient for life. It is present in every cell type in every organism and is vital to the well being of all organisms.* Adult human bodies contain about 24 grams of magnesium, with 60% in the skeleton, 39% intracellular (20% in skeletal muscle), and 1% extracellular.
ATP (Adenosine Triphosphate), the main source of energy in cells, must be bound to a magnesium ion in order to be biologically advice.* Over 300 enzymes require magnesium ions in order to function.* Magnesium in one of its various forms (ie: gluconate, malate, orotate, magnesia, citrate, etc) can be used in a number of situations where stabilization of abnormal nerve excitation and blood vessel spasm is required in otherwise healthy/normal nerves and blood vessels.*
The average adult human daily nutritional requirement is set to 300 to 400 mg per day of elemental magnesium. Inadequate magnesium intake frequently causes bodily discomforts such as muscle spasms, as well as potentially more serious health concerns. Human magnesium deficiency (including conditions which show few overt symptoms) is relatively common, with only 32% of the United States meeting the RDA-DRI, and has been implicated as a potential antagonist in a number of human illnesses.*
Due to its basic structure / function, magnesium may effect muscle relaxation through direct action on the cell membrane.* With the addition of magnesium, more channels may be blocked and the nerve may have less activity which could help support the body in reducing the itching / crawling sensations commonly noticed during periods of rest or sleep.*
According to a randomized, double-blind study, done in 2003, scientists found Magnesium Citrate to be more bioavailable than oxide or amino-acid chelate (glycinate) forms.*
Now to answer the question: Why did we use Magnesium Oxide in our Magscorbate®? What folks don't understand that Dr. Wong has taught is that the elemental magnesium in all chelated magnesium products is Magnesium Oxide! All chelated minerals are a blend of the mineral source and the chelating agent. The chelating agent is always cheaper than the mineral source so they put in a lot of that and little mineral. The industry standard would look like this: 85% citric acid and only 15% magnesium oxide (using magnesium citrate as an example) which is why a lot of people who use those products experience diarrhea even at low doses.
