Great

Magnesium is a standard supplement for all stages for my horses. It's essential in so many metabolic functions.

Amazing product

Great product

Excellent product!!

Good communication. Fast shipping. Had the product I wanted!

Madbarn.ca supplements are easy to feed. And work. The magnesium has made a huge difference in the horses. When you own multiple horses finding one supplement they will all eat can be tricky. I have been impressed.

Love it, a great inexpensive Magnesium finally!

I can not believe how Mad Barn's Magnesium has helped my mare with her cycle. It felt she would start her cycle in January and not come out of it until the end of March. She has never had a foal but she would bag up to the point I could milk her. Now when her cycle comes I notice it for about two weeks, and she no longer is bagging up.

It is a very consistent product. Not certain if it actually helping my HSS horse but he was on it when I bought him 5 months ago and have continued with it.
