Mega-Mag™ is rated 4.7 out of 5 by 56.
Rated 5 out of 5 by from Relaxes muscles This helps my older horse with a stiff back. When she is on magnesium she warms up more quickly.

Rated 5 out of 5 by from Great for OTTB! 3-4 year old OTTB mare who is on 50/50 alfalfa and grass hay diet responded BEAUTIFULLY to this--especially her weight and topline, the "dip" between her neck and withers disappeared! Feet look great, coat is blooming. She will stay on it!

Rated 5 out of 5 by from Great vitamin supplement Very palatable, and has everything the horses need.

Rated 3 out of 5 by from Horse spit it out Bought this because of the desired ingredients. Gave my horse a scoop by hand and he spit it out ... two days in a row. Doesn't smell very appealing. Because he will leave his entire grain ration with his meds in it, I don't dare use this.

Rated 5 out of 5 by from I bought this for my mini mare that was in need of a good vitamin. Love the pelleted form and she had no problem eating it all up !

Rated 5 out of 5 by from Great product! 30days in and we have had a very noticeable difference in our mare who has tons of anxiety and little focus when off the farm

Rated 4 out of 5 by from Multi-Vitamin I really like this product--I love the pelleted format, and I am confident that the product is supplying the correct amounts of vitamins and minerals to complement his alfalfa-based diet. However, this is the first supplement I have encountered where no scoop is included for measuring. Typically a scoop is included by the manufacturer for accurate measuring, and I was disappointed to find that there was nothing included in this bag of supplement. While I think it's a great product and my horse eats it with no problem, I am unsure that he is getting the exact amount required.

Rated 5 out of 5 by from so far so good! needed to supplement his alfalfa based hay forage. he's already on SmartCombo Ultra (wonderful stuff!) and this seemed to fit the bill as an add-on. it's now part of his smartpaks. best part, he loves the tase so no problems getting him to eat it.

Rated 5 out of 5 by from Great to take "the edge" off I began using this product about 6 weeks ago, and can already see marked improvement in my gelding. I chose Mega-Mag because it contains far more than just additional Magnesium, including a wide variety of vitamins and minerals for supplementation to my horse's diet. I heard great things at our barn regarding the use of magnesium to help higher strung horses become more calm and focused. My gelding often becomes spooky at the slightest things, jigging one way or another for really no reason. Over the past month I have seen a marked improvement in his behaviors. Last night we were able to walk from our indoor to outdoor arena without balking - this would not have happened a few months ago. I no longer worry that a ray of light on the area floor will cause him to stop mid stride. I am very happy with the results, and have also added this to our high-powered Arab's diet, hoping for the same.

Rated 5 out of 5 by from Perfect for my feeding program Since we feed straight alfalfa this product is perfect to help keep our feed program balanced! Bonus is the horses readily eat the pellets!!
