Artificial added magnesium from feeds and supplements is probably doing your horse more harm than good. We are in the bizarre position of having conducted blood trials, collected years worth of data from customers and studied the science (which all supports us) yet the pro-magnesium lobby is so strong that we have even been banned from a Facebook group for having the temerity to ask proponents of magnesium to support their arguments with science. They can't.
Why are we so concerned?
1. It is our view that horses sedated with artificial magnesium sources are less able to make safe decisions. Our company policy is not to sell products that run a significant risk of making riding more dangerous. Clearly many other feed and supplement companies don't agree with us.
2. Excess magnesium interferes with a cellular process called calcium signalling (CS). CS is what switches almost every cell in our body on and off - so it is crucial.
Our unique chelated calcium technology supports calcium signalling. It is clear from years of monitoring customer feedback plus blood trials that chelated calcium works less well when artificial magnesium levels in the diet remain too high.
This collection of articles (select from the menu below) tries to pull together our trials, the published science and our customers' feedback and enable you to read a side of the story that others do not want you to see. I will be trying to edit this group of articles over the next few weeks to make them a little more coherent than they probably are at the moment (December 2019).

Watch this short video for an extreme example of the negative impact of artificial magnesium on an eventer that had been described as a "jumping machine". The good story starts at about 1:40.
