Magnesium glycinate mixed with Magnesium oxide

2018-09-03

Magnesium is one of the most used natural health products for good reason, it does so many beneficial things. It relaxes tight muscles, calms nerves, widens blood vessels and reduces inflammation just to name a few. From a physiological perspective, it is one of the key lynch pins of your cellular energy production so it is no surprise it has so many applications.

Regarding magnesium products and the increasing amount of elemental magnesium. Below is a summary of the different forms of magnesium and the % of magnesium in each form.

Studied to penetrate past the blood brain barrier

Brain injuries, cognition, memory, focus

 

One of the most popular forms is magnesium glycinate. We obviously want higher amounts of elemental magnesium but this immediately raised some red flags because dosage calculations just don`t add up. As you can see in the above chart, the percent of elemental magnesium for magnesium glycinate is 11-14%, this means the maximum elemental magnesium would be 100-120mg.

 

You are probably asking how is it possible to get 150 or 200mg of magnesium glycinate per cap? The label clearly states magnesium glycinate as the only medicinal ingredient. The only plausible answer is it`s NOT pure magnesium glycinate. What else is it then? The likely culprit is magnesium oxide, with a much higher percentage (58%) of elemental magnesium, could be combined with magnesium glycinate to inflate the total elemental magnesium content on the label. While adding magnesium oxide to magnesium glycinate is not going to harm a person, it may increase the likelihood of having loose stools without increasing magnesium levels effectively.
