Rated 5 out of 5 by from Great changes in young TB This has made a huge difference for my rambunctious young TB, his naughty baby behavior is pretty much non-existent since I started this supplement. I was skeptical a supplement could make such a difference but I am sold! I have him on 2 scoops a day, will try to wean to 1 soon and see if it is enough..

Rated 2 out of 5 by from Crazy horse I am not one to leave bad reviews but oh my gosh, this makes my gelding crazy! I put him on this to help his muscles. He was on the suggested dose and got the crazies. I reduced his dose and he still was fresh. Took him off of it because I figured he probably has enough magnesium in his diet. After changing hay from 2 alf 2 grass to all grass, I figured I should give it a try again. I couldn’t believe his reaction to the supplement. He is quite calm in general so it was very obvious. I wish it could’ve worked out because magnesium is amazing! He did eat this despite being very picky.

Rated 4 out of 5 by from Not for us Bought this for my picky and tight-muscled gelding. Good news: he ate it right up! Bad news: it made him fresh. I have seen this product do wonderful things for my barn mates but not for us! He is usually quite calm and only gets concerned at shows. This stuff had him kicking his heels up much more than usual! I was hoping it would help his tight muscles relax.

Rated 5 out of 5 by from Palatable and Effective This is a high quality and effective magnesium supplement from a reputable brand that is in pellet form and easy to feed.

Rated 1 out of 5 by from Upset stomach My horse was on this supplement for less than a week when he started having SEVERE diarrhea. We live in Florida where dehydration is worrisome and with how much fluids he was losing, it was not okay. I had to go in and cut each one of these out of his smartpaks so the barn manager wouldn’t accidentally continue feeding. Extremely disappointed and a complete waste of money.

Rated 4 out of 5 by from Worked Great - Mare Stopped Eating For the time my mare did eat this supplement I noticed a positive change in her demeanor and behavior. Unfortunately the last time I ordered, she immediately went off of her feed. I first thought it was the Vitamin E pellets I started her on, but she ate those with no issue. I offered her the magnesium pellets by themselves and she refused. After taking out this supplement, she is eating again. I just ordered the Ultra SmartCalm and I hope she will eat them.

Rated 4 out of 5 by from Simple Like the pellet, easy to feed, taste seems to be attractive to horses.
