They found this increased rate of absorption correlated with increased cellular protection from toxic pesticides and concluded that vitamin C-lipid metabolites (PureWay-C) have potent antioxidant and significant free radical scavenging capabilities. 28 Magnesium deficiency can contribute to everything from depression, loss of appetite and headaches to abnormal heart rhythms and fibromyalgia, according to Metabolics, a dietary supplement provider in the United Kingdom. Sacharin R., Taylor T., et al. Blood levels and bioavailability of ascorbic acid after administration of a sustained-release formulation to humans. Int. J. Vitam. Nutr. Res. 1977; 47: 68–74. A question that has been presented to me numerous times is "What kind of vitamin C should I take, and why?" It is a very good question, indeed. Let’s look at the different types of vitamin C that can be found in many of the capsules, powders and liquid vitamin C supplements available today… Erythorbic acid is an isomer of ascorbic acid. Isomers are compounds that have the same kinds and numbers of atoms, but different molecular arrangements. The difference in molecular arrangement among isomers may result in different chemical properties. Erythorbic acid is used in the US as an antioxidant food additive and is generally recognized as safe. It has been estimated that more than 200 mg erythorbic acid per capita is introduced daily into the US food system. Unlike ascorbic acid, erythorbic acid does not appear to exert vitamin C activity, for example, it did not prevent scurvy in guinea pigs (one of the few animal species other than humans that does not synthesize ascorbic acid). However, guinea pig studies also indicated that increased erythorbic acid intake reduced the bioavailability of ascorbic acid by up to 50%. In contrast, a series of studies in young women found that up to 1,000 mg/day of erythorbic acid for as long as 40 days was rapidly cleared from the body and had little effect on the bioavailability of ascorbic acid, indicating that erythorbic acid does not diminish the bioavailability of ascorbic acid in humans at nutritionally relevant levels of intake (17).

Eating magnesium-rich foods found in both plant and animal sources such as seeds and nuts along with whole grains, beans and leafy green vegetables is one way of obtaining magnesium. For reasons discussed earlier, obtaining sufficient magnesium from food sources and diet alone may not always be achievable, particularly if you are showing signs of severe magnesium depletion. Magnesium Phosphate is practically insoluble in water. Magnesium is bound to phosphate in teeth and bone. Magnesium Carbonate It’s easily absorbed and doesn’t have the strong laxative effects characteristic of other forms ( 28). An older 2003 study of 46 adults found magnesium citrate absorbed better than magnesium oxide and magnesium chelate. A decline in magnesium status is associated with various symptoms such as depression, psychosis, irritability or confusion.Magnesium is an essential co-factor in fatty acid metabolism that impacts upon hormonal health.

Bull. 2011; 34:1744 – 1747. It’s typically taken orally to replenish low magnesium levels. Due to its natural laxative effect, it’s also sometimes used at higher doses to treat constipation.

When considering taking supplements for more magnesium, discuss it with your doctor. High levels of the mineral can interact with antibiotics and some medications. Electrolytes are minerals in the body that have an electrical charge. Calcium, magnesium, sodium, potassium, chlorine and phosphate are all electrolytes. Levels of electrolytes can become too low due to sweating, vomiting, diarrhoea or even over hydration. The balance of the electrolytes is critical for the normal function of cells and organs.

The extent of water solubility of magnesium compounds plays a part in magnesium’s availability and oral absorption. Those forms that dissolve well in liquid are more completely absorbed in the gut than less soluble forms. Organic magnesium salts are, in general, more soluble than inorganic magnesium salts.
