E-Se-Mag Pellets is rated 4.8 out of 5 by 40.
Rated 5 out of 5 by from Love this product. I have used MVP products before both Vitamin E and Magnesium but I didn't know they made a product with both of them in 1! I was very excited when I found them on Smartpak's website. I feel like any horse with an extensive work load benefits from E-Se-Mag.

Rated 5 out of 5 by from Good Price, seems to be working Affordable and seems to be doing well for our older arthritic horses. Upstate NY we are low on SE so its only a bonus to supplement it.

Rated 5 out of 5 by from Great results ! We started our OTTB on E-Se-ag Pellets as his work load was increased, and I wanted to avoid any soreness or stiffness - we were so pleased with the results, and even his demeanor seemed happier and more relaxed !

Rated 5 out of 5 by from quick results I bought this 3 weeks ago. within a week I noticed both my mares winter coats becoming super soft. 2 weeks they were both gleaming. I live in New England so we are low on Se. Very happy with this product, will continue for sure. Good price too. One of my mares is a very picky eater and eats it no problem.

Rated 3 out of 5 by from Less "touchy" so far None of my horses have access to year round green grass, and summers bring very little grazing on our property in the high desert. Even though they are all on custom mixes of feed and forage, alfalfa, 24/7 grass hay, etc., my mare has always been thin skinned and very sore after workouts (with PEMF, chiro, massage, stretches specifically designed for her, and oh so much more maintenance than we all would like to admit, haha). She has been on this for 2 months and is so far seeming less sore after a work out. I will update the review after the hard riding season gets underway!

Rated 5 out of 5 by from Great for horses increasing work load I've had my mare on this for a couple of months now, and put her on it as she was put into work with a trainer. She went from no work to working 5-6 days per week and didn't have any sore days, even after intense lessons. She is 14 years old, and has no maintenance. I love this product! I have transitioned all of my horses onto it.

Rated 5 out of 5 by from Good for horses on low or no forage My horse does not play well with others, so he has to go out by himself, a situation with which he is very happy, thankfully. However, he doesn't get the nice, lush pasturage the other horses get, as he is in a smaller solo paddock. He gets very high quality hay out there and alfalfa in his stall, but after he'd been without good forage for a while I was worried he wasn't getting enough Vitamin E. My horse is fat, shiny, and bursting with health- he is a jumper and has always felt ready to jump big fences. However, I had noticed he was much more sensitive to being brushed over the past year, when his pasturage changed to very little grazing. The things is that when I added this supplement very quickly he was suddenly back to not caring about being curried. So, I don't know if the Vitamin E and/or Selenium and/or Magnesium helped, but it is the only thing I changed and I am happy to have my mellow dumblood back again! He likes it and eats it up, although if I gave him a cheeseburger he would probably eat that, so his hooves up review may not be worth much, but I'm the one paying for it and it seems to be working, so we will keep him on it!
