I originally purchased this for my appendix who has lousy feet and EPM. I'm always looking for ways to sneak in more vitamin e. He was noticeably different within about 6 weeks and the farrier is very happy with the results 6 months later. You can actually see when I started feeding it to him in his hooves. It took a little bit, but my fussy TB finally started eating it, too. He's a bay and this is the best coat color he's ever had. I definitely recommend to everyone as it's very well priced (especially in bulk) and the customer service is on point! I also love the feed nutrient calculator on the site.

As a veterinarian who specializes in keeping animals healthy with nutrition, I want to feed my horse as naturally as possible. This supplement is a great balance for my horse's forage based diet. The customer service in this company is excellent, as are the quality of ingredients.

Easy 1 scoop for the average horse doesn't just meet, but exceeds NRC daily guidelines. No issues with palatability.

As far as I can tell, it's working! It's at a great price point, too.

Easy 1 scoop for the average horse provides the full NRC daily guidelines. 20mg of biotin in highly palatable distillers grain and wheat midds. Full dose biotin at a fraction of the cost of the pre-formulated hoof supplements. Great if you are following a low sugar/starch diet formulation for your horse.

Unfortunately I have not seen significant improvement in my horse's itch response and hypersensitivity since starting Spirulina roughly 5 weeks ago. I am continuing on this product in hopes of further improvement. However, MadBarn have been great to work with.

This item was well packaged and just what I needed. It was as described and delivery was extremely fast. I will use Mad Barn again!

Was here in 2 days!!!!

My IR horse is usually fairly well controlled, with a strict diet (in terms of extras), free choice hat and regular work.This winter though, nothing I did could keep the weight off and I was starting to have to look at more specialized interventions.Decided to give mad barn a chance... 8ish weeks later (with no knowledge of his dietary changes), my farrier was shocked at how good my horse’s feet looked! His feet virtually fell apart, around this time last year, but they are great this year, even with a big abscess growing out.His weight is great and dapples are coming in nicely. Over all, very happy with the supplement choice!
