I originally bought this to improve my horse's allergies, as her eyes weep and crust a lot. After about a solid month of using it, her eyes still weep, but there's a lot less irritation around them and her other skin issues have improved greatly. In combination with her other madbarn supplements (jiaogulan, w-3 oil, omneity), her skin, coat, hooves, and inflammation have improved. She is less cresty, her fat deposits have lessened, and she looks very shiny and healthy. She does not like the taste of the spirulina, but I toss her supplements in with soaked teff pellets in place of grain and this masks the taste very well. The w-3 oil also helps!

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. 😅😂

Have not noticed anything yet from this supplement, on 2nd bag and pony doesn’t like the taste and wastes most of it even mixed with molasses.

I love this product, but wish it were pelleted.

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

Horse would not eat it. No idea if it works.

Arrived quickly!

I've been using the Spirulina for 2 months now. I can't say I notice any difference in my horse. The powder is very messy and stains anything it touches. I can't say I'm the biggest fan but I want to give it more time before I make a full decision on if this is worth the money or not.

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.

It works pretty well- fast difference from coughing
