This stuff is WORKING! I wish it was pellets and not a powder. But my horses are not scratching their hair off yet! My kid with mud fever doesn’t have it anymore! My kid that has breathing issues, not coughing! My kid that is super itchy, is not itchy! Magic bullet? I think so!

This product seems to really help both my 23 year old cushings mare as cushings causes them to be immunocompromised. And my gelding who 15 and has COPD he is on both this and jaiogulan and the combination has really helped.

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

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!!!

Rarely any more do you get customer service that is polite AND prompt. This company does. As far as the product, I trust what’s in the bag is the true thing and not mixed with unnecessary things. My horse had less allergy reactions throughout the summer. His weight was easier to maintain (a much too easy keeper), and he didn’t reject eating it daily. I will be purchasing this item again. Satisfied customer.

Hi, I emailed about this a couple weeks ago, but no reply yet. I'd like to request a refund. My horses would not eat it, and I had to stop because their mashes were going to waste. They receive other vital medicine and supplements in the mash so I couldn't use the Spirulina. Thank you so much

Appears to be working for my mare with insect bite hypersensitivity.

I’m not ready to make a review yet. I would like to finish feeding this bag first.

Spirulina has ended allergy eyes in my horses. It's also sped up healing from scratches, we've had a wet winter here in Central Virginia. I'm keeping them on it!

I have a very picky mare worh aweet itch. This is the only Spurulina she will eat and believing it will really help her sweet itch. I didnt find Mad Barn till last year well into the season so we are hopeful for relief this summer
