    Wonderful product can’t rate it high enough. It has helped my horse tremendously as he suffers terribly with summer allergies, buttercups, flies, wasp etc and other other insects due to his compromised immune system.

    I can’t lie this supplement stinks horrible – but it works! It does exactly what it says on the package and stops my old 22 year old mare coughing her lungs up when stabled and despite the smell she has no problem gobbling it all up in minutes! Who would’ve thought such a natural and bank friendly supplement would be such a good send?!

    I have fed this to one of our young Arabs now for just over a year. This horse came to us with no mane and tail and bald areas of skin. He now has balanced minerals everyday, forage focused to the grass he eats. He has grown the most amazingly long mane and tail, has a superior shine to his coat and his muscle tone is fantastic! I would certainly recommend this product and this system of feeding and supplementing horses.

    Spirulina is just the most amazing super-food. It helps my hunter build muscle and it also supports the bodies natural anti-histamine processes for my itchy youngster. A great side effect is super-shiny coat too!!!!
