Magnesium: Frequently asked questions

What types of Magnesium are there and what determines a good product?

There are several types of Magnesium, but the most common is Magnesium Oxide. It’s cheap and easy to find in any supermarket or pharmacy. However, it has a low absorption rate (about 6%) which means that you need more than usual amounts to get the same effect as other forms like magnesium citrate or glycinate.

The quality of the Magnesium is determined by its purity and bioavailability. A good Magnesium should be free from heavy metals, have low levels of impurities such as sodium or calcium, and it should also not contain any other minerals that could interfere with absorption (such as zinc).

Who should use a Magnesium?

Anyone who is experiencing symptoms of magnesium deficiency should consider using a Magnesium supplement. This includes people with chronic fatigue, fibromyalgia, migraines and headaches, muscle cramps or spasms (including menstrual cramps), restless leg syndrome (RLS) and other sleep disorders such as insomnia. People suffering from depression may also benefit from taking a Magnesium supplement since it has been shown to have antidepressant effects in some individuals.

Based on what criteria should you buy a Magnesium?

We recommend you to choose a Magnesium made of high quality materials, not too expensive and fast delivery.

Make sure you compare the milligram strength of each product. Some companies will try to sell a low grade at a higher price, but that doesn’t mean it’s a good value. We only carry Magnesium Citrate and Malate in 200mg capsules for maximum absorption.
