Helps my horse a lot with respiratory and itching issues, but it is messy, as any spirulina powder is.

I use this year round for my two horses. Helping with immune system, greens they need and respiration issues from allergies

Powder is a little messy lol

I live the quality AND the price-cant find better. But! That's not the main reason I feed my equus. All 4 have health-issues -I already see a difference in each. I will continue to use as supplement

Great products and fast delivery!

Love it. Really helps my older mare with her allergies

My PPID horse with moderate heaves has been on Spirulina for 1 year now…I swear his heaves “attacks” have all but diminished. We have drastically cut down on his Dex injections as a result, which is such a relief! Mad Barn Spirulina is always super consistent in quality too. Highly recommended if your horse has allergies or breathing issues.

I have 3 with copd and one usually has to use 2 inhalers a day thru allergy season and this year we have not used them at all

This is a great product and has helped my OTTB's skin immensely. Shipping is very quick. I really like this company and their products.

I have a pony with seasonal allergies and skin issues. Adding the spirulina to his nutrition has been a clear support to his system. I have confidence in purchasing from Mad Barn.
