It works pretty well- fast difference from coughing

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.

Arrived quickly!

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

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. 😅😂

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

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

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.

My horse absolutely loves this product. I feel good knowing that he is getting the absolute best from Mad Barn. He licks the bottom of his food bowl every time.

Game changer for my horses gut health
