Pros of Magnesium Oxide
The main thing about magnesium oxide when it is used as a supplement, is that is the preferred form of magnesium for many pharmaceutical companies. This is due to it being so cost effective.
It has a high magnesium content relative to a low mass. This means that you are getting a lot of bang for your buck – you only have to swallow 1 magnesium oxide tablet to consume the same magnesium as 4 magnesium citrate tablets for example.
That is where the good stuff about magnesium oxide stops.
Cons of Magnesium Oxide
When you are looking at the back of that magnesium supplement bottle and scratching your head wondering just what is magnesium oxide, consider this: magnesium oxide has the lowest bioavailability of all the magnesium supplements. This means if you are taking a tablet that contains 100mg of magnesium for example, your body only absorbs a staggering 4% of the magnesium. (source: The Magnesium Miracle by Dr Carolyn Dean) That’s only 4mg. That is a lot of tablets you need to take before you reach the recommended daily magnesium intake of 320mg – 420mg! (NIH)
A lot of magnesium oxide supplements also contain an additive called stearate which is usually considered unnecessary, and is actually harmful in large quantities.
What is Magnesium Oxide Doing?
Not much actually.
96% of magnesium oxide is digested and excreted by the kidneys without going anywhere near the places it is needed most. What it is not doing is being absorbed and used by the body (source: The Magnesium Miracle By Dr Carolyn Dean)
If you are magnesium deficient like 75% of Americans today, then you need a better supplement to fulfil your needs.
Magnesium is required in over 300 enzyme functions. It keeps the electrolytes in balance, the skeleton strong and regulates your heartbeat. Magnesium produces energy and regulates the hormones needed for sleep. It digests and metabolises the food we eat, while reducing stress and facilitating smooth muscle and nerve actions.
Sufficient levels of magnesium is vital for everyone’s health and wellbeing.
Therefore, magnesium oxide is not an appropriate or recommended magnesium supplement.
Or you could try applying magnesium oil directly onto the skin if you don’t like to swallow tablets or capsules and want a more pure and organic form of magnesium chloride.
Now that your question of what is magnesium oxide has been answered, you should be able to tackle your choice of magnesium supplement with much more information at hand.
