Magnesium, with the symbol Mg, is a silvery, light metal that is not seen nature except in combination with other elements, such as calcium, carbon, and oxygen as in the common mineral dolomite.  It makes up about two percent of the Earth’s crust making it the eighth-most abundant element in the universe and the third-most abundant mineral dissolved in seawater (with a 0.13% concentration).  Magnesium, as a metal, can be mixed with other metals, particularly aluminum to make cans of drinks, car bodies and other light but strong items.  Due to its flammability, Magnesium is used for flares and fireworks and was used to make incendiary bombs during World War II.  Magnesium is also an essential component of Milk of Magnesia including hydrogen and oxygen molecules, which works as a treatment for indigestion and as a laxative.  Biologically, it is part of chlorophyll which is the green pigment that plants use to extract energy from sunlight. It is crucial to more than 300 biological processes in the human body.  Doctors also prescribe magnesium supplements for some medical conditions like diabetes, high blood pressure, and premenstrual syndrome.


Magnesium bicarbonate

Also referred to as Magnesium Hydrogen Carbonate, Magnesium bicarbonate is the bicarbonate salt of magnesium which can be formed via a reaction of dilute solutions of magnesium hydroxide (milk of magnesia) with carbonic acid (seltzer water or club soda).  It is a complex hydrated salt that is found only in water and under certain conditions.  There are different varieties of non-supplemental and supplemental Magnesium.  However, one variety that is not difficult to consume and which is bioavailable is Magnesium Carbonate.  Water supplemented with magnesium bicarbonate is an excellent source of orally available magnesium.  It is never found in capsule or pill form as it only exists in aqueous solution.  Magnesium carbonate is the result of the drying of Magnesium bicarbonate.

Magnesium Carbonate Solubility

Magnesium Carbonate is not soluble in water because according to the solubility rule, all carbonates except those of alkali metals are insoluble.


Constipation refers to a medical condition wherein an individual is not able to pass bowel for at least seven days or passes a meager amount of intestine in less than three times in the seven days. Primarily poor diet is the natural cause of constipation and is most times made worse by inadequate or minimal exercise and also by fecal stasis in the colon.  Lack of water intake also causes constipation.  Water intake does not only imply drinking multiple glasses of water, but it also means the addition of the right juices to our daily drinks.   Medical conditions can also lead to constipation, e.g., Irritable Bowel Syndrome.

Common symptoms of constipation among others include few bowel movements, trouble having a bowel movement (straining to go), Hard or small stools, a sense that everything didn’t come out and Belly bloating.

Most constipation treatments involve diet and lifestyle changes. Drinking warm liquids in the morning as well as the addition of two to four extra glasses of water daily help elimination. Also, a higher fiber diet and increased fruits and vegetable consumption help to remove constipation.   Physicians may recommend a laxative or a stool softener in some cases but must be taken as prescribed because they can weaken the muscles of the bowel.

Magnesium Carbonate Powder

The chemical formula MgCO3 represents Magnesium carbonate.  It is a white, powdery compound that occurs in nature as magnetite and dolomite.  It is sold globally as a health supplement.  The active ingredients of Magnesium carbonate are magnesium which is a mineral that is necessary for efficient functioning of your body.  The normal human body contains about 25 g of Magnesium, with the bone housing half of this.

Magnesium Carbonate Uses

There are many medicinal properties of Magnesium carbonate apart from prevention and treatment of magnesium deficiency.  Magnesium carbonate is used in both foods and medicines.  It is a form of magnesium which is required by the body in small amounts for good health.  Depending on their age and gender, Magnesium carbonate should be consumed by adults daily (between 310 and 420 milligrams) as it is important for regulating blood sugar, nerve and muscle function, protein formation and blood pressure regulation.




Laxatives refer to a group of medicines that are used for treating constipation. They can be given through the rectum as suppositories and enemas or via the mouth as capsules, liquids or tablets.  Suppositories are pellet-shaped and are inserted into the rectum, through the anus while enema is a liquid that is inserted into the rectum through the anus.

Laxatives are grouped into four main groups based on how they work.  They include:

Osmotic laxatives work by increasing the fluid level of the large bowel by drawing fluid into it (i.e., osmosis).  The bloodstream then absorbs less liquid from the large bowel; hence the intestines are fuller because of the extra fluid.  This leads to the stimulation of the bowels’ walls to contract and these muscle contractions (peristalsis) leads to squeezing out of the faces.  Examples include phosphate enemas, sodium citrate enemas, lactulose, and macrogols.

Stimulant laxatives work by stimulating the nerves of the large bowel or large intestine.  This then leads to the squeezing of the large bowel wall muscles harder than normal, hence pushing the stool out in the process.   Examples of stimulant laxatives include glycerol, senna, bisacodyl, docusate sodium, and sodium picosulfate.

Stool softeners work by softening and wetting the stool, e.g., Liquid paraffin and arachis (peanut) oil enemas.

Bulk-forming laxatives or fiber supplements increase the bulk of your stool in a similar way to fibers.  When the water in your stool has been absorbed, the bulk of it increases, and this stimulates the muscles in your gut to squeeze stool along and out of the body.  Fibers are not digested, rather it stays in the gut and it is passed out with the stools, hence adding to its bulk.  Examples include husk, methylcellulose, unprocessed bran, and sterculia.
