Good product but lacks iron This product was recommended to me by a SmartPak employee. My horse ate it without a problem, and my horse looked good and healthy. I was happy with it until I realized that it has no iron in it. My vet told me to find a multivite that has iron because it's important for giving your horse a healthy amount of energy, and my horse tends to be on the lazy side as it is, so I suspect the lack of iron in his diet was making him even lazier. I switched to Accel - pricier, but has everything in it. May 9, 2013
Very Happy with the Results I've waited a little while to comment on this supplement because I wanted to give it enough time to see how things went. Well, I have to say that I have seen a big change in my horse since starting him on this multi- vitamin/mineral supplement. To give a brief background on my horse, he is only four years old and last year he became very sick and we battled for about 6 months to save him. During that time, my vet advised to change his feed to Equine Senior and only give a small amount; that small amount is only two pounds a day, just enough to mix in his supplements to feed. Needless to say, I knew he wasn't getting his recommended vitamins and minerals with his feed, so I searched for something to supplement for that. Since he was being feed Alfalfa, I opted for the Mega Mag. My guy is solid black and since putting him on this, it looks like he has dapples on his coat; he has really bloomed on this stuff. He has put on the weight since adding this to his smart paks, so I am going to have to cut him back on his hay and grain a little now, but he looks awesome!!! He acts likes he feels great so all in all…… I am pleased with this choice so far! April 22, 2013
Good value, very palatable My horse eats these without any grain. His coat is looking good and I especially like the price. Will continue to use in my horse's smartpaks. April 30, 2012
Mega Mag Have used the product about 45 days and noticed my horse has more energy , great coat and shine. He started shedding in Jan. as our winters are mild here in Calif. Would highly recommend this product February 17, 2012
Love this product! i purchased mega mag when i rescued my, at the time, just turning 1, baby horse. when i bought him he was just 300 pounds and had absolutely no life in him. I bought this in hopes of getting as much in him as safely as i could. within just a couple of weeks he started showing improvements! I was amazed how quickly the stuff worked on him February 2, 2012
Happy Horses, Happy Owner I bought this product hoping to supplement my horses through the winter months when they aren't on good grass and need extra nutrients and vitamins that can't be provided by hay alone. We've only used it for a month but I can't believe how nice their coats look. Normally that long, scruffy winter hair seems a bit dull, but this winter they are shiny and my palomino's wooly coat has even dappled! They all seem happy and healthy and that makes me happy.
