Magnesium Supplement Benefits
As a key element in over 600 biochemical reactions in the body, adequate levels of magnesium can result in numerous health benefits.
Primarily acting as a supporting mineral, the availability of magnesium is essential for optimal health.
One of the most important roles magnesium plays is that of helping to create energy for our cells.
The mitochondria inside our cells need magnesium to create energy for in the form of ATP to keep us alive and functioning.
Without magnesium, the nutrients we absorb could not be metabolised into usable forms of energy.
Our cells then use ATP to as their fuel source or energy to carry out other function such as: 3
Cell Reproduction
create new cells and support cell division
Protein Synthesis
create new proteins from amino acids
Muscle Fibre Contractions
contract and relax muscles properly
Gene Maintenance
create and repair DNA and RNA
Nervous System Regulation
regulate messages between brain and nervous system

Magnesium Rich Foods
Magnesium is found in many vegetables, especially leafy greens, as well as in nuts, seeds and legumes. Foods with plenty of fibre are usually high in magnesium.
It is best to always try get as many vitamins and minerals from a healthy balanced diet. The magnesium in food is often absorbed far better than supplements so a small amount may go a long way.
Unfortunately, with the lowering levels of magnesium in our food, even a diet filled with these foods might not be enough for a stressed person, which is where a supplement would be necessary.
Magnesium Supplements
There are many popular forms of magnesium supplements out there. However, some are much better than others. Absorption rates between different types of magnesium vary between 4% and 30% which is why it is always important to check which form is being used.
Recommendations:
Magnesium citrate offers one of the best absorption rates and is reasonably priced. It consists of magnesium bound with citric acid making it water soluble and very well absorbed.5 It is one of the most popular forms of magnesium for supplementation in top quality products.
Magnesium Glycinate is magnesium bound with the amino acid glycine, an exceptionally bioavailable form of magnesium. This type of magnesium is popular as it is less likely to cause a laxative effect while still being well absorbed.6
Avoid the poorly absorbed magnesium supplements such as oxide, gluconate, sulphate and carbonate.

Magnesium citrate a well absorbed affordable form of magnesium but at high doses is not well tolerated by the gut. Magnesium malate is a great form due to its slow release property. Being bound to malic acid which also has it’s own health benefits, it’s absorbed well, but slower than most. Chelated forms like magnesium glycinate are generally well absorbed and easy on the gut because they’re bound to amino acids our body recognises and can use. Check out our magnesium supplement buying guide or all the various types of magnesium supplements for more recommendations. -
Can I overdose on magnesium?
