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.

This spirulina calmed my girl’s cough in about 5 days. I’m afraid to take her off it!

My horse ate it well in the beginning but now will not eat so I no longer use it

My horse was diagnosed with "immune mediated keratosis" brought on by allergies (we think). My vet told me about a study involving spirulina and a barn full of TBs in which it it appeared that supplementing with spirulina, environmental allergies were positively affected and symptoms mitigated. So I tried it. On my third bag and we haven't had a flare up. 😁 It's messy though. 😅😂

Horses didn't like it. I stopped giving it to them. It's messy and powdery.

Arrived quickly!

This has helped a bunch with my older rescue mare with itching. She evidently has an abnormal histamine response problem. She has healed all the sores from scratching on trees and appears more comfortable.
