My 20 yr. old Lusitano has a very sensitive gut and this is the only product I have found that prevents diarrhea. I have been giving him Spirulina once daily for 6 months and I will continue!

Bought spirulina. Great product just gets everything green. Wish there was a pellet because at times my donkey didn't eat it since it went to the bottom of his feed even when wet. Overall good product.

It helped with coughing. The green color is all over, & every other horse too. From them going & checking out if there is any left overs , when they are done with theirs.

I absolutely LOVE MadBarn and the Spirulina product. My mare eats it up with her pellets and Amino Trace supplements!!! She was so sick when I got her back, but since getting her on MadBarn products, her health is pristine!!! I'm so grateful for your staff and all the help they have offered me every time I've called in!!! I tell everyone I know about MadBarn products!! They are the BEST!!!

I specifically ordered this to aid in my geldings allergies and it has helped tremendously! Even without giving it to him consistently everyday, it has giving him so much relief from the typically itching neck.

Love the product but your bags are horrible!! They don't close at all and the product spills all over, especially the green powder. Please fix your bags.

My horse developed hives on his stomach, neck, under belly, etc within a week of slowly introducing it. A few days after I discontinued it, the hives disappeared

Great product. Handy that it comes in two-pack supply. Picky horse likes it! Not seeing a tremendous improvement in his allergy type issues but overall happy.

My horses didn't like the taste at first, but they liked their pellets enough to eat it. They got used to it after a while. I didn't notice a difference in anything so I chose not to repurchase. I do think it's high quality.

It seems to be helping my pony, who had an allergic skin reaction to something.
