Mad Barn products are exceptionally good in general. However, I have not been able to assess the effectiveness of the Spirulina product as I was too annoyed at dealing with it's physical components. The dark green powder is extremely messy to work with, and temporarily stains contact items. It's probably a useful supplement based on the research, just awkward to use.

I am sure that it could be a great supplement, but none of m'y horses like the taste.

Mon cheval ne veux pas le manger même si je le mélange avec sa moulée. L'odeur est vraiment forte et désagréable.

My picky Arab horse would not touch his feed if it contained even the smallest amount of this ...sadly
