    Mega-Mag™ is rated 4.7 out of 5 by 52.
    Rated 5 out of 5 by from Perfect Vitamin Supplement This vitamin supplement is great because it has all the vitamin and minerals horses need in appropriate doses. It is a great value and doesn't have any fillers or preservatives. It's great for horses who don't eat powdered vitamins.

    Rated 5 out of 5 by from who is this mare? I had a nervous, shy, and easily spooked horse that I literally do not recognize now. Since I put her on Mega-Mag, she has put on some much needed weight, has a beautiful coat, and can now show off her wonderful disposition.
    Date published: 2008-02-26
    Rated 5 out of 5 by from Great Multi-Purpose! Great product! Provides vitamins, minerals and pro-biotics in one very palatable supplement! I have a growing youngster on Mega-Mag and a mature horse with skin problems and it is doing both of them wonders!
