Mega-Cell™ is rated 4.7 out of 5 by 245.
Rated 5 out of 5 by from Great vitamin supplement I've been feeing Mega-Cell for a long time. It's a great vitamin supplement with NO added iron. I have a high level of iron in my well water so I'm careful to watch for any added iron. It even gives my chestnut dapples. :) All my horses, donkeys, and mule eat it just fine. Plus, it's affordable!

Rated 5 out of 5 by from Nice Overall Addition to my Horse’s feed I bought this to ensure that my animals were getting all of the proper nutrients. I have noticed my horses are looking better and have their heads in the game a little more, and yet it has not made them hot at all. Love the price, it makes it easy to continue.
Date published: 2021-07-31
Rated 5 out of 5 by from Great vitamin/mineral supplement, reasonable cost I’ve only been using this for a month but so far so good! My horse gets an infinitely small amount of grain and still eats this readily.
Date published: 2021-03-08
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.

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.

Rated 5 out of 5 by from Great stuff My mare is on a forage only diet (Timothy/orchard) & I’ve always supplemented with a vitamin/mineral product to make sure she gets everything she needs. I’ve tried 2 other “top brands” that were pretty pricey & believe it or not, LACKED certain vitamins/minerals (according to FeedXL). But this one, Mega Cell, is IT! Everything my horse needs & her diet is balanced. Her hooves are great, her coat is dappled out, & she is healthy. I will keep her on this forever. I mix it in with her hay pellets & she eats it right up. Very affordable too!
Date published: 2019-11-07
Rated 5 out of 5 by from Picky eater approved! I've been feeding this to my gelding for almost a year and he's usually picky but will eat this right up. I love that it has everything in it that he needs to balance out his oat diet.
Date published: 2019-10-10
Rated 5 out of 5 by from Great Value The best vitamin/mineral supplement for the price I have found, love that it has probiotics and amino acids
Date published: 2019-07-04
Rated 5 out of 5 by from The look of perfect health. I bought this product a month ago as my horses don't require the recommended amount of feed to maintain a healthy weight, and I wanted to make sure they were getting their vitamins and minerals. Since we stared my mare seems less cold backed and seems to warm up so much faster. My geldings coat went dull, to soft and shiny. And they both have put on an impressive amount of muscle. I've gotten so many compliments about how they look this past week or so and that alone makes it worth it.

Rated 5 out of 5 by from Love the products and my horses do too! Finally a well rounded product. That dose not cost a fortune.
Date published: 2018-11-05
Rated 5 out of 5 by from Vet Approved!! I had my horse on this and she did very well. Unfortunately, she became laminitic, and I took her off so I could add a different supplement. My vet is a very thorough label reader, and told me to take her off the other supplement and put her back on this one, so I did, and could NOT be happier!! This isn't just a supplement - it's a staple now in her diet.
Date published: 2018-08-10
Rated 4 out of 5 by from Great product Love the mega cell. I like that it is very constrated. My only regret is not getting it in smart packs.
Date published: 2018-03-22
Rated 5 out of 5 by from My horses love it! Great supplement to add to my horses diets, they love it and I love the price!
Date published: 2018-01-18
Rated 4 out of 5 by from Great for a picky eater My mare can be a picky eater when it comes to supplements in her grain, but she loves this one and so do I! It is inexpensive and has better vitamin levels then some of the more expensive “top brands”. It smells like sunflower seeds and makes my horse shine even in the winter!
Date published: 2018-01-17
Rated 4 out of 5 by from Horses seem to like it Was looking for a supplement to give my horses who are on hay year round and limited grain. Have tried others but was looking for one that was pelleted. They didn't care for Vita Flex which was a powder. I didn't care for the smell with that one or this one but they seem to eat this supplement well and its seems to be one of the cheaper ones out there. Plus, for what my horses are used for they don't need a vitamin mineral supplement with real high levels of vitamin/minerals. Just something to fill in the gaps. Just wish it had more Biotin in it. But if someone asked if this made a difference in how they look. I see no difference.
Date published: 2018-01-02
Rated 4 out of 5 by from Good Supplement but horse won't touch it This seems like a great supplement and I won't down vote it since my horse won't eat it I can't see it's affects or such.
Date published: 2017-12-17
Rated 5 out of 5 by from Works great for my horse! I have had my horse on this since I got him and he has thrived. I have tried other multi-vitamin supplements and honestly they just don't work as well. I always switch back. What I like is that it is a balanced supplement. There is not too much of one thing which can cause adverse effects in some horses.
Date published: 2017-12-15
Rated 4 out of 5 by from Excellent Supplement I purchased this Supplement a month ago for 2 ponies and a horse to supplement their grass hay diet. I am very happy. The horse and ponies have dappled, shiny coats and I feel it fills any nutritional gaps. All of them eat the Supplement and seem to like the taste.
Date published: 2017-07-25
Rated 5 out of 5 by from Excellent product! I bought this product for my 5 year old mustang mare. She's an easy keeper, so I want to keep her fit but make sure she gets good nutrition. This supplement has a great balance of everything, is low calorie, and is economical. It looks to be complimenting her grass hay well; she's a copper penny chestnut and actually has faint dapples! Everyone who sees her thinks she looks great.
Date published: 2017-07-06
Rated 5 out of 5 by from Great product for the price I have had my 3 horses on this vitamin for over ten years. My 30 year old Hanoverian looks and acts like she is 15. No sway back or loss of muscle tone.The other 2 are 22 and 25 years old. They look and act healthy. Gorgeous coats! Knock on wood, but I haven't had an emergency Vet call in several years.
Date published: 2017-02-22
Rated 5 out of 5 by from Seems to be working! My guys have been eating this for a little over a month now. In the last week or so I've noticed that my draft seems to have more energy than usual...which is a good thing :-))) Now when he sees me and starts walking towards me I can yell "ruunnnn" and here he comes! He looks happy and it makes me feels like he's getting everything he needs to be healthy.
Date published: 2017-02-02
Rated 3 out of 5 by from Good Product I was looking for an all around vitamin supplement to give since I feed oats. It needed to be cost efficient since I feed 16 horses. Mega Cell met those requirements and an added bonus was that they didn't fade nearly as much this past summer as they had being on another supplement.
