I have been using Mad Barn’s spirulina for some time in my horse’s diet. It helps his immune system, making him less reactive to insect bites, and adds more amino acids to his forage based diet. Additionally, MB’s Spirulina price point works well for my feeding budget.

Horse not a fan of this product but will keep on hand for another horse

I am quite happy with this! My horse loves it! And I feel better about having a way to support him when the air quality from smoke isn’t great. Thank you for the advice and the product!

I love it but ny picky horse stopped eating it :( He was good for the first 2 containers, but when he started eating green pasture, he wouldn't touch the feed with spirulina in it anymore.

I am extremely happy with the product. I have been giving it to my elderly mare who has battled heaves her whole life. She came into spring extremely underweight and I thought I was going to lose her. I started giving her your product in a mixed grain and she gained weight again, shedded out beautifully, and I saw her run the other day. My mare is 30 years old also battling cancer in her eyes. I’ve been suggesting your web site to all my horse friends. Thankyou so so so much!!! I’ve owned this horse for 25 years and am hoping I can love her for a few more.

My 18 yr old Morgan has Heaves and I feel Spirulina is helping him quite a bit.

Love this product!

Spirulina, in combination with a few other Madbarn products, has completely changed my horse's breathing for the better!

Love this , needed to add some maple syrup at first . We have not used any bug spray , our guess is it’s a side effect:) He looks great has not had any allergy symptoms at all and I am saving a lot . Thanks so much

So for me unfortunately I didn’t see a difference in my horse, but I don’t have anything bad to say either, it was really easy to order, came quickly, my horse didn’t object to it, he wasn’t sure about the fact his food was a bright blue green the first day, but after that never blinked at it. The bag lasted a little more than a month, which I appreciated as I feel that is a long enough time to gage if it’s going to be a good fit or repeat purchase.
