Love this for my horses, one is laminitis prone and this has been great. The other has helped with focus and the calming properties have helped. Would definitely recommend.

Feedmark Magnesium is excellent value. I have given my pony Magnesium as she can be unsettled in a spooky way, and a little mareish at times. It really helps her ability to be more settled and to concentrate.

Good product has kept my horse sane!

Better than any calmer and works

A big difference after just a few days. Pony much calmer and less jumpy. Will carry on and also add other calmers. Hoping this will eventually leas to a happy relaxed pony.

A very small amount seems to be making a huge difference in my horses nervous excitability especially around grass flush time. Evidence shows we are all deficient in this mineral at certain times.

Perfect for helping my boy stay more relaxed and ideal for managing his tying up. So easy and convenient

Magnesium keeps my very anxious horse calm

Guest - 17/03/2025 19:22

Arrived quickly and so far so good, is doing what it’s meant to and will be reordering when we need to, very palatable.

This is great - my Dales tends to get cresty and he can also be spooky, so I wondered if he might be deficient in magnesium. This magnesium is better than other brands I have tried as it is such a tiny scoop. I have noticed a difference quickly in his demeanour and I am hopeful I have started feeding this early enough to stop him developing a cresty neck this summer.
