Optimum Digestive Health from Mad Barn has been a huge tool in helping my sensitive mare find a happy gut balance throughout weather changes or stressful events. She has had a few colics over the years but since starting this supplement she has been much more consistent and I fret much less thank goodness! High quality supplement that I highly recommend if your horse has a sensitive digestive system.

My mare is allergic to a few key feed ingredients and this supplement works perfect for her to balance her strict diet while helping to maintaining her coat and body condition as well. I buy the big bag and store it in a garbage can. It keeps extremely well!

all four of my horses feet have shown huge improvement especially through floridas rainy season

Seems to have helped with the bug bites.

So 2nd year using Spirulina and no antihistamines....it is keeping her sweet itch under control along with a fly sheet and mask

Very good service. Tank you

I had a horse that was coughing due to round bale dust. I changed to squares and started feeding Mad Barn Spirulina and Jiaogulan. I have not heard her cough in the 2 months she has been on the supplements. Even started giving to the mini mule when he is out on grass since that seems to give him allergies.

Being able to tonuse one scoop instead of carefully measuring out the correct ratio is very helpful.

My name is Kim. Well, its been a month and a half since I started Buddy on MagneChrome and Spirulina and a month since he started the jiaogulan . Up to date, hes lost weight and feels great. The cresty neck has shrunk! I didnt think it was going to go away so fast. Hes 23 and we started him on an exercise program due to his boredom. Hes just doing great and looking great. Im so glad I came across this MadBarn site. I also have to say that he also had a heavy breathing thing going on and that is nearly gone. Crazy.
