    Magnesium 5,000 is rated 4.7 out of 5 by 292.
    Rated 5 out of 5 by from we can trail ride again! I used to fox hunt in addition to show dressage when I first got my OTTB. As he gained weight and a top line he started rearing, bucking, spooking and displayed nervous energy. I had to stop trail riding all together and was still nervous for those naughty moments in the ring. After 1 week on magnesium I had my sweet boy back. He's low drama again and after 1 month we've even been venturing back out on the trail after 3 years! I have also noticed some improvement with an old muscle injury- weve made the transition from 1st level to second level because I trust him more and he is using himself. I'm a veterinarian and NEVER expected such results- intially I tried it to appease my trainer. Wow- she was right!

    Rated 5 out of 5 by from Works!! I started my two horses on it a few weeks ago. Seems to be helping.
    Date published: 2020-09-01
    Rated 5 out of 5 by from Solved Horses Anxiety My horse is very anxious throughout the ride and while standing saddled up. Chews at the bit pretty consistently pulling it into his back molars. No dental issues. Straight anxiety. The magnesium SOLVED this problem. No more chewing and chopping. Stands quietly while getting groomed and when saddled. Did not help with the spookiness per say, but i am pleased it helped with the anxiety.

    Rated 4 out of 5 by from More focus My horse has only been on this about a month but I'm starting to notice him being more focused when we're working.

    Rated 3 out of 5 by from Nice Product This product helps just take the edge off. Horse eats it with no issues
    Date published: 2020-07-16
    Rated 5 out of 5 by from Amazing I got this for my mare when other calming supplements failed her. Since starting her on this she has a puppy dog personality. She remains calm when things are busy around her while riding. This is one thing I will never go without. Also thanks to Smartpaks, she always gets the right amount everyday and I dont have to worry about running out.

    Rated 5 out of 5 by from Works wonders! I have a 5yo ottb who has always been hot and a very forward ride. We tried a few calming supplements and none really worked. My picky eater doesn’t have any issues eating it and it has helped his demeanor tremendously and he will stay on it for the foreseeable future.

    Rated 3 out of 5 by from Seems palatable Horse ate it ok. Unsure if it helped or not. Could have been just seasonal change.
