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

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.

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.

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.

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!

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.

Great product! I use it for respiratory support for my 2 geldings. Delivery is quick and product seems quality.

My order was lost in the mail so I contacted Mad Barn. They tried to track it for me me. Next contact from them was to say they had shipped a replacement for me! Great customer service and great products.

Love this way of supplying spirulina, it can get expensive. This is a low cost easy way to get the results we need for allergies! We combined with Jiaogulan it’s been great for my mare!

This product has helped my mare who suffers from IBH during the warmer months here in Texas.
