    Mega-Cell™ is rated 4.8 out of 5 by 232.
    Rated 5 out of 5 by from My donkeys eat it right up! This is my second month of Mega-Cell and I'm so happy that my donkeys are eating it. I had tried other similar products- many of them much more expensive- and very pleased that not only is this affordable, but tasty and it works!! WIN, WIIN, WIN!

    Rated 5 out of 5 by from Picky Horse Approved I bought this product about 6 months ago and have been using it since. My horse is very picky, so it can be difficult to find things he will eat. He'll eat these pellets on their own or with his grain. I can't say that it has made any difference in terms of health, but I think it's good to feed since he does not have much access to grass, especially once winter hits.
    Date published: 2020-10-14
    Rated 5 out of 5 by from noticeable results! I use this for my 2 year old horse that is on a primarily grass diet to round out her nutrition, and wow. Noticed a difference in just over 2 weeks. Coat got shiner, she developed DAPPLES(swoon) and her topline/muscle development appeared to improve. Super palatable, no issues eating it either.
    Date published: 2020-07-21
    Rated 5 out of 5 by from Keeps me coming back! I think my only issue with Mega-cell is that our horse's egos might be getting a little inflated with all the compliments they get. Both horses are incredibly shiny, have gorgeous dappling, non-fading, bold color, healthy feet and ultimately seem to be happy, more balanced animals. Both my picky horse and horse that eats everything are happy to eat it plain, too. We are very pleased with the price and performance of this product. I have tried other products that claim to do more. They only thing they seem to do better is deflate the pocketbook. Nothing else beats Mega-cell, in my opinion.

    Rated 5 out of 5 by from I’ve had my horse in the MVP Mega-Cell for 3 years after adopting him. He has foundered, feet long/ no heel and stretched white line. Within a few months of him being on the vitamin we began seeing improvement. In addition to the improvement to his feet, his coat is healthy & shiny. This vitamin is the perfect balance to his forage based diet without the unnecessary additives seen in many other products; this is especially nice for horses that are IR or have chronic laminitis.
    Date published: 2020-06-30
    Rated 3 out of 5 by from Nice balance of vitamins and minerals I tried this when I could no longer acquire another supplement. My very picky horse ate Mega-Cell without any problem! I had hoped it would help keep his skin in good condition, but no luck there - so my 3-star review is that I wanted a skin&coat helper and bought the wrong product to accomplish this. His bloodwork and weight were good AND he ate it rather than shuffling it to the side and leaving it behind. Good product, just not the result I was hoping to gain.
    Date published: 2020-06-28
    Rated 5 out of 5 by from Does exactly what it says! A great price, and a great result! I noticed a difference in a month. The horses were excited to eat, and they’ve filled out in their coats. Their hooves are growing faster too.
    Date published: 2020-06-26
    Rated 5 out of 5 by from I haven’t had the product a long time but my horse seems to enjoy it and her coat is beautiful this summer.
    Date published: 2020-06-24
    Rated 5 out of 5 by from Great overall vitamin! I’ve noticed a definite difference in my mares overall state of being since starting this. She feels much more balanced and level headed. I was looking for something to add to her diet since she is on a forage first/no grain diet. This was a nice addition to her feeding program!
    Date published: 2020-04-06
    Rated 5 out of 5 by from Great value supplement I use the FeedXL program combined with forage testing to get a better picture of what my horses'diets look like. Mega-cell was a perfect fit to fill in the areas their forage was lacking in. It has a great price and doesn't take much to meet their daily needs. I would recommend to others as a great "balancer" type mineral to round off what a horse may be lacking from forage alone.
