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.

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.

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.
