Magnesium 5,000 is rated 4.6 out of 5 by 306.
Rated 5 out of 5 by from My horse has been on this for over a month and I definitely see a difference in her behavior,much calmer and more focused which makes a much nicer show horse

Rated 5 out of 5 by from Amazing Product I bought this last month as my horse has muscle spasms due to a magnesium deficiency. Not only has the spasms decreased, but she is more comfortable when exercising!
Date published: 2018-11-14
Rated 5 out of 5 by from Reasonable priced magnesium supplement I've been feeding this almost two months and see a slightly more focused horse than before. I had hoped for a more significant improvement with spooking and being distracted. Will give this product another month or two before I pass judgement.

Rated 5 out of 5 by from Great results I bought this for a gelding who tends to get alittle tense and upset if he feels like he's done wrong, and this season of showing he has just been a different horse. More relaxed, doesn't get as flustered. It's been a huge difference.

Rated 5 out of 5 by from Best magnesium supplement Very palatable pellet, good with picky eaters. I love the fact that you can easily double the dose safely for performance horses and it doesn't have other things in it that I don't need.
Date published: 2018-09-18
Rated 3 out of 5 by from It may help a little bit I bought this about 5 weeks ago for my 20 year old gelding who was acting quite studdish. I wanted to keep him calmer in general so he could gain more weight. I see a bit of a difference in his handling on the ground, and he is the same willing horse under saddle. Not a drastic change, but he’s better than before.

Rated 5 out of 5 by from Great product Good price and product. Shipping was fast and easy! Seems to help with anxiety of one of the horses.
Date published: 2018-07-16
Rated 5 out of 5 by from Total game changer for me My horse was very tight and anxious most rides. After about a week on the supplement he has become so much more relaxed and happy and very much looser and more fluid through his body. He is becoming my dressage boy that I knew he could be. I will definitely be keeping him on this supplement. Only slight draw back is I'm not sure he's thrilled with the taste but mixing in an applesauce cup seems to have fixed that right up.

Rated 5 out of 5 by from Love this supplement! I’ve been giving this to my TWH gelding for the last 3 months and I’ve noticed a huge difference. He is a lot calmer and his muscles have relaxed and is able to stay in longer after chiropractic adjustments!
Date published: 2018-06-13
Rated 5 out of 5 by from It works I did not realize how well this was working on my 2 mares until I quit feeding it to them. As soon as I realized what was going on I immediately placed another order and I cannot wait to get it. They were both less anxious, less spooky, and more calm. I would definitely recommend.
Date published: 2018-06-05
Rated 5 out of 5 by from Great product that works I had a mare that I was at my witts end with. Someone suggested this product to help level her mood swings out and it has exceeded all my expectations. She is now a level headed horse that I can rely on! Great product after trying many that failed to help.
Date published: 2018-05-16
Rated 1 out of 5 by from Not working at all Says for nervous System horses but I think it is making my worse. She is had completely changed since starting and not for the better I will be taking her off and not buying again
Date published: 2018-04-18
Rated 5 out of 5 by from no change in behaviour but he loves it i can't knock the product, as i was skeptical about a supplement making much of a difference, but he does eat it very willingly. i got this, thinking it could help my OTTB relax while he is being groomed (he hates being brushed) and relax in general; but i guess he was not lacking magnesium in the first place, which is also good i guess.
Date published: 2018-04-10
Rated 2 out of 5 by from Not sure what to think I am in the middle on this product. My horse is a picky eater and ate it great, but I did not notice a difference in him at all. I don't think that it gave desired results. Price is good if it worked.
Date published: 2018-04-02
Rated 3 out of 5 by from Great Company I bought magnesium 5,000 twice now on auto ship, only think I wish they do is 30 days not 28 days cause I was out for couple of days... but great product and easy on making grain for my horse.
Date published: 2018-03-08
Rated 5 out of 5 by from Seems to be doing the trick! I was having problems with spookiness and overall nervousness with my new dressage horse. The behavior was coming on very gradually, so I knew something must have been deficient in his diet. He had already been treated for gastric ulcers, which had healed. I tried this after reading many reviews. His behavior has totally changed as has his attitude both under saddle and on the ground. I will keep feeding this supplement permanently.
Date published: 2018-01-08
Rated 5 out of 5 by from Great addition to my supplements I tried this supplement for its calming abilities. Definitely noticed an improvement in my horse, more relaxed on the ground and under saddle. Other people that handle him also noticed a more relaxed behavior after being on this supplement.

Rated 5 out of 5 by from Great product! This is the 4th time purchasing this product, which I give to all my horses!!!
Date published: 2017-12-19
Rated 4 out of 5 by from Not a real difference in our horse I did not really see a change in our guy. He had classic symptoms of a deficiency and was on it for almost 6 weeks. No symptoms improved. He ate it fine and didn’t make problems worse. Just not what our guy needs I guess. I know it works for others so I would still say try it as it is easy to feed and not a huge expense.

Rated 5 out of 5 by from Magnesium is a life saver!!! All of my horses are on Magnesium. Amazing, affordable supplement. Highly recommended!!!
Date published: 2017-11-15
Rated 5 out of 5 by from Fantastic product Tried and true. Works great for my own horses muscle tightness and for a clients spooky arabian. Truly changed the Arabians nervous and jittery demeanour into a much calmer and quieter animal.
Date published: 2017-11-13
Rated 5 out of 5 by from Horse no longer panics My horse has been on this for a couple of months. Prior to, my Anglo-Arab would spook, then work himself up so much he would go into a panic in the cross ties. These episodes would happen a couple of times a week. He was also very tense through his back, and showing all other signs of magnesium deficiency. He’s still a hot blooded horse but there is a noticeable decrease in tension and we have not had a panicking episode since!
Date published: 2017-11-12
Rated 5 out of 5 by from Difference is noticable I had heard good things about it so thought I would give it a try. I could tell a difference in just a couple days. Worth a try.
Date published: 2017-09-24
Rated 5 out of 5 by from Huge difference My gelding had extreme anxiety his first show season, so someone recommended putting him on a magnesium supplement, so of course I turned to smartpak. It has worked wonders. He's more relaxed at shows and is no longer a fire breathing dragon!!
Date published: 2017-07-18
Rated 5 out of 5 by from Love the ease to feed Bought this supplement to help my mare's hooves. Can't wait to see if it helps. The daily prepackaged amount is the best. Makes giving it super easy.
Date published: 2017-07-11
Rated 4 out of 5 by from Seems to be working My horse eats this with other supplements with no problem. I got this on advice of my trainer. Seems to do the job.
Date published: 2017-06-27
Rated 5 out of 5 by from Amazing change in my paranoid/schizophrenic! My large pony developed Cushings and insulin resistance. He became dangerous with his paranoid/schizophrenic behavior (not common with Cushings).I have had him since he was born, and I could no longer catch and halter him in a corral without him frantically bolting away, running over me, and finally standing with every muscle on rigid alert. The magnesium was a miracle for him. He has become my sweet boy again, relaxed and affectionate. I wouldn't have believed it if I hadn't seen it with my own eyes.
Date published: 2017-06-11
Rated 2 out of 5 by from Caused diarrhea I gave the suggested dosage for my 11 y/o ottb and within 1 day he got diarrhea. I called smartpak to see if diarrhea is ever a problem, and the representative said "no, we've never heard anything like that." I politely told her there was an old review on the website that complained about the supplement giving a horse "loose stool." After speaking with my vet, he said he would suspect diarrhea being caused by the magnesisum supplement. I immediately stopped using the supplement.

Rated 3 out of 5 by from Simon has been on this for almost 2 months. I haven't seen any improvements.

Rated 5 out of 5 by from Good result This has helped my mare be less touchy while grooming
