    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.

    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.

    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!

    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!

    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.

    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 5 out of 5 by from Very nice with a hay diet Having switched to a complete hay diet I was looking for a multi-vitamin to go along with it. I choose this for price and for what was in the ingredients. Perfect for a horse that is not being worked hard.
    Date published: 2017-11-24
    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.
