In this supplement by Pure Encapsulations, you'll find 50 milligrams of magnesium citrate along with 11 milligrams of vitamin C in each easy-to-swallow vegetable capsule.

What is Magnesium Citrate?

Magnesium citrate is among one of the most highly bioavailable magnesium chelates (others include aspirate, citrate/malate and glycinate), which support the metabolism and use of many other essential nutrients. Magnesium also plays a role in many enzymatic and physiological functions, including cardiac function, neuromuscular contractions and regulating the acid-alkaline balance within the body. Along with other minerals, magnesium is used by the body to restore itself to an alkaline state when it is undergoing periods of excess acidity. Acidity, or acidosis, can be caused by exposure to toxins or a poor diet (high in acidic foods).

How the Body Uses Magnesium

The body uses magnesium (and other minerals) to metabolize macronutrients, produce energy and to efficiently use phosphorous, calcium, sodium and potassium. This essential mineral also helps the body use vitamins C and E (which are powerful antioxidants) and B-complex vitamins (which play a large neuro-protective role).

Building Strong Bones: In addition to vitamin D, calcium and phosphorous, magnesium is essential for maintaining good bone health. One trial that involved over 2 thousand seniors indicated that higher intakes of magnesium were directly related to increased bone mineralization in certain individuals.

Heart Health: Although magnesium is well-known for its role in bone health, magnesium also provides a broad spectrum of cardiovascular support. It supports arterial function, C-reactive protein metabolism, lipid metabolism and endothelial function. A review of 20 different randomized trials suggests that magnesium can also promote healthy systolic and diastolic function, meaning that it may help the body normalize blood pressure. In addition to all that, magnesium has also been known to promote healthy glucose metabolism. One study that spanned 15 years and involved over 4,500 young people indicated that higher intakes of magnesium may be associated with healthy cardiovascular function and glucose utilization.

In addition to all of the benefits listed above, magnesium also plays vital roles in muscle function, cranial vessel comfort and mood. It has been known to have a calming effect.

Where Does Magnesium Citrate Come From?

Magnesium comes naturally from limestone. The citrate is made through corn dextrose fermentation. The other forms of bioavailable magnesium (aspartate, glycinate and malate) are synthetic. Ascorbyl palmitate comes from palm oil and corn dextrose fermentation.

Magnesium Deficiency

Since magnesium is abundantly found in leafy green vegetables, a true magnesium deficiency is rare. However, individuals who suffer from malabsorption disorders are advised to supplement in order to get adequate amounts of magnesium in their diet. Also, since magnesium is used by the body to restore the acid-alkaline balance, those who eat an overly acidic diet should consider supplementing with magnesium citrate, such as is found in this supplement by Pure Encapsulations. Side effects from taking magnesium are extremely rare because the body naturally gets rid of excess magnesium.
