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 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

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.

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.

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!!!

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.

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.

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!

The product is good, but very messy. Pellets would be better. One of the reasons I was buying your products was for the customer support, which was good for the first time. The second time I was grilled by the person who answered the phone and then I had left a message and after two weeks of no response, I sent a Facebook message. I was told that her dog had died the day that I called. I certainly felt sorry for her, however she should have had someone as back up. For now, I will not be ordering and looking for another source for my horses and ponies.

I love how the Mad Barn Spirulina helps my gelding with dust sensitivities. He was previously on MVP Airway EQ and that worked great the first year. It seemed to stop being effective and my gelding was coughing terribly. After a couple vet visits for diagnotics, I decided to try Mad Barn Spirulina. I saw a significant improvement! In fact the cough went away completely. I now feed it to both of my horses daily and I recommend it to a lot of people I ride with who also own performance horses. My only request, please start producing it in a pellet form. It is quite messy due to being such a fine powder.
